Agenda Item 1.2: to consider in-band power limits for earth stations operating in the mobile-satellite service, meteorological-satellite service and Earth exploration-satellite service in the frequency bands 401-403 MHz and 399.9-400.05 MHz, in accordance with Resolution 765 (WRC-15).

BACKGROUND

Resolution 765 (WRC-15) calls for the necessary technical, operational and regulatory consideration of the possibility of establishing in-band power limits for earth stations in the EESS and MetSat services in the frequency bands 401-403 MHz and in the MSS frequency band 399.9-400.05 MHz taking into account the results of ITU-R studies.

The frequency bands 401-403 MHz and 399.9-400.5 MHz are used for Earth station uplink transmission by the Data Collection System (DCS) under the Earth exploration-satellite service (EESS) and meteorological-satellite service (MetSat) and the mobile-satellite service (MSS) allocations. DCS Earth stations as knows as data collection platforms (DCP) are deployed worldwide and communicate with GSO and non-GSO satellites.

The Data Collection Platforms (DCP) is a network of sensors measuring and gather information activity related to the Earth, environmental and scientific applications, weather, environment observation: meteorological and oceanographic, seismic observation, volcanology, geodesy and geodynamics, fishing vessel monitoring, wildlife tracking, homeland security, law enforcement, test/evaluation, monitoring shipments of dangerous goods, humanitarian applications, managing water resources or tsunami warning system.

The data collected by DCPs are transmitted to GSO and non-GSO satellite networks using the non-GSO MSS allocation in the band 399.9-400.05 MHz or the meteorological satellite allocation in the band 401-403 MHz. These systems usually operate using moderate to low equivalent isotropically radiated power (e.i.r.p.) levels, resulting in small link margins.

These frequency bands are also used by non-geostationary satellites for telecommand space operations (see RR No 1.23) under the EESS, MetSat services, or under the MSS allocations and a growing number of these satellites are planned. The output power levels of the earth stations at the antenna port peak e.i.r.p. of these telecommand links (Earth-to-space) can be much higher than the moderate to low power levels used for the DCS service links, leading to potential harmful interference to DCS satellite receivers.

Recommendation ITU-R SA.2045 provides information on the performance and interference criteria for relevant geostationary-satellite orbit (GSO) and non-geostationary satellite (non-GSO) DCS in the frequency band 401-403 MHz. Recommendation ITU-R SA.2044 provides information on the current and future usage of non-GSO DCS in the frequency band 401-403 MHz, and the portioning of the frequency band to allow all DCS equal access to the spectrum. Recommendation ITU-R M.2046 provides a description, and the corresponding protection criteria for broadband noise and narrowband interference, of one MSS system that uses the frequency band 399.9-400.05 MHz (Earth-to-space).

ITU-R studies considered in-band power limits for earth stations operating in the frequency ranges 399.9- 400.05 MHz in the MSS and 401-403 MHz in the EESS and MetSat services.

[Reason: ITU-R studies results have shown a need to provide in-band power limits applicable to Earth stations in order to ensure the existing and future operation of DCS in the MSS, EESS, and MetSat service will continue to operate without interference.]

Option 1

Support: Canada, Mexico

ADD DIAP/1.2/2

5.C12 In the frequency band 399.9-400.02 MHz, the maximum e.i.r.p. of earth stations in the mobile- satellite service shall not exceed 5 dBW. Until 22 November 2029, this limit shall not apply to satellite systems for which complete notification information has been received by the Radiocommunication Bureau by 22 November 2019 and that have been brought into use by that date. Administrations are encouraged to make all practicable efforts to comply with the limits in the frequency band 399.9-400.02 MHz prior to 22 November 2029. (WRC-19)]

Reasons: A frequency range of 30 kHz without e.i.r.p. limits would accommodate a typical telecommand link taking account of Doppler shift effects (e.g. typical link bandwidth of 9.6 kHz + Doppler shift of +/- 8 kHz). Existing and planned telecommand functions for satellite systems notified and in service by the end of the conference would continue to operate at their existing power levels for 10 years, which corresponds to the end of life of existing satellite systems.

Until 22 November 2029, this limit shall not apply to systems for which complete Advanced Publication Information has been received by the Radiocommunication Bureau prior to 22 November 2019.

Reasons: The frequency bands identified in this new footnote are intended for operation of non-GSO DCS. Therefore, the long-term deployment of new telecommand earth stations in these frequency bands is to be avoided. Existing and planned telecommand functions for satellite systems notified and in service by the end of the conference would continue to operate at their existing power levels for 10 years, which corresponds to the end of life of existing satellite systems.

ADD CAN/1.2/3

5.B12bis In the frequency band 401.7-402.850 MHz, the maximum e.i.r.p. of earth stations in the meteorological-satellite service and the Earth exploration-satellite service shall not exceed 22 dBW for geostationary systems and non-geostationary systems with an orbit of apogee equal to or greater than 35 786

The maximum e.i.r.p. density of earth stations shall not exceed −17.8 dBW/Hz for non-geostationary systems used for telecommand operations. Until 22 November 2029, this limit shall not apply to systems for which complete Advanced Publication Information has been received by the Radiocommunication Bureau prior to 22 November 2019.

Reasons: A non-GSO system with a telecommand earth station operating with an e.i.r.p. density of −17.8 dBW/Hz would be able to meet the protection criteria of DCS systems using GSO or HEO satellite systems. This value is based on the sharing analysis conducted by the ITU-R taking into account possible mitigation measures that can be used by the telecommand operations to minimize potential interference to DCS systems. Furthermore, an e.i.r.p. limit is proposed for non-GSO DCS with an orbit of apogee lower than 35 786 km for the band 401.7-402.850 MHz even though there are no such operations according to the DCS band plan, since non-GSO DCS stations could nonetheless operate in this band under the METSAT and EESS allocations. Finally, existing and planned telecommand functions for satellite systems notified and in service by the end of the conference would continue to operate at their existing power levels for 10 years, which corresponds to the end of life of existing satellite systems.

9 CCPII-2019-33-4357_i 29.05.19 Agenda Item 1.3: to consider possible upgrading of the secondary allocation to the meteorological-satellite service (space-to-Earth) to primary status and a possible primary allocation to the Earth exploration-satellite service (space-to-Earth) in the frequency band 460-470 MHz, in accordance with Resolution 766 (WRC-15).

Resolution 766 (WRC-15) - Consideration of possible upgrading of the secondary allocation to the meteorological-satellite service (space-to-Earth) to primary status and a primary allocation to the Earth exploration-satellite service (space-to-Earth) in the frequency band 460-470 MHz

BACKGROUND

The purpose of this Item on the Agenda is to determine whether if it is possible to modify the allocation of the meteorological-satellite service (MetSat) (space-to-Earth) from a secondary basis status to a primary basis status, and to make a primary basis status allocation to the Earth Exploration-Satellite Service (EESS) (space- to-Earth) in the 460-470 MHz frequency band.

This should be carried out giving protection and without imposing additional restrictions to the existing primary services to which the frequency band is already allocated and to the services in the adjacent frequency bands, respecting at the same time the conditions stipulated by RR No. 5.289.

Report ITU-R SA.2429 presents the studies and elements that serve as basis for Item 1.3 of the WRC-19 Agenda. This report also includes the initial technical considerations about EESS and MetSat in the 460-470 MHz band and other services with allocations in this band and in the adjacent bands, namely the mobile service, the maritime-mobile service, the mobile-satellite service, the fixed service and the broadcasting service.

The 460-470 MHz frequency band is currently allocated to the fixed and mobile services on a primary basis and it is widely used by them. Resolution 766 (WRC-15) establishes the need to protect fixed and mobile services in the 460-470 MHz frequency band and not to limit their future development.

In addition, RR No. 5.286AA identifies the 450-470 MHz frequency band to be used by administrations wishing to implement International Mobile Telecommunications (IMT).

The 450-470 MHz frequency band, due to its propagation characteristics, offers the possibility to provide adequate coverage in rural and suburban areas with a low density of radio base deployment with respect to the higher frequency bands, allowing access to Internet in areas of low capacity demand through IMT systems.

On another note, according to the CPM Report, some administrations consider that it will be necessary to conduct further studies to be able to determine the PFD limits for GSO satellites and reach a conclusion about a single mask, based on the two options established in Report ITU-R SA.2429, and also that there will be a need for new studies taking into account the mobile service systems that require greater protection, such as PPDR applications, of GSO and non GSO satellites, as established by Recommendation ITU-R M.1808-0.

Likewise, the solution methods proposed in the CPM Report for the present Item on the Agenda recognize as a disadvantage the existence of potential cause of harmful interference into the terrestrial service stations when more than two non GSO and GSO satellites of MetSat/EESS operate simultaneously in the same frequency band within the same service area.

12 CCPII-2019-33-4357_i 29.05.19 Agenda Item 1.7: to study the spectrum needs for telemetry, tracking and command in the space operation service for non-GSO satellites with short duration missions, to assess the suitability of existing allocations to the space operation service and, if necessary, to consider new allocations, in accordance with Resolution 659 (WRC-15);

BACKGROUND The demand for suitable spectrum for NGSO satellites with short duration missions is growing due to the increasing number of these types of satellite missions. The mass and dimensions of these satellites contribute to their success and their use will likely grow. These types of missions provide an affordable means for scientific and commercial space purposes and are increasingly used by new entrants in space. Nevertheless, it is important to ensure that these missions do not cause harmful interference to existing systems and incumbent services. WRC-19 Agenda Item 1.7 invites studies to accommodate spectrum requirements for telemetry, tracking and command (TT&C) in the space operation service, below 1 GHz, for NGSO satellites with short duration missions in existing bands or identify new spectrum supported by sharing studies. The term “short duration mission” used in Resolution 659 (WRC-15) refers to a mission having a limited period of validity of typically not more than 3 years, where the operator does not launch replenishment or replacement spacecraft. With regards to the spectrum requirements for SOS for satellites with short duration mission, studies show that between 0.625 MHz to 2.5 MHz is required for downlinks and between 0.682 MHz and 0.938 MHz is required for uplinks. The frequency ranges described under invites 3 of Resolution 659 (WRC-15) overlap with allocations critical to global maritime distress and safety service (GMDSS) frequencies, identified in Appendix 15, and centered at 156.3 MHz, 156.525 MHz, 156.65 MHz, 156.8 MHz, 161.975 MHz, and 162.025 MHz, as well as frequencies used for the safety of life COSPAS/SARSAT system in the band 406-406.1 MHz. In the frequency band 137-138 MHz, the mobile-satellite service is subject to coordination under No.9.11A as per footnote No.5.208. In the frequency band 137.025-137.175 MHz and 137.825-138 MHz, the space operation service (space-to-Earth) is not subject to coordination under No. 9.11A since the mobile-satellite service has a secondary allocation. Therefore, 0.325 MHz of spectrum is currently suitable for satellite with short duration missions. This only partially addresses the spectrum requirement identified for short duration missions in the space-to-Earth direction.

The World Radiocommunication Conference (Sharm el-Sheikh, 2019), considering a) that the term “short duration mission,” as used in this Resolution, refers to a mission having a limited validity period of no more than 3 years; b) that the tracking, telemetry and command links for NGSO satellites with short duration missions pertain to the space operation service; c) that these satellites have restrictions in terms of reduced on-board power and antenna gain; d) that No. 5.C17 identifies the bands 137-138 MHz (space-to-Earth) and 148-149.9 MHz (Earth-to-space) for such applications; e) that the studies conducted by the ITU-R show that other frequency bands, aside from those indicated in considering d), allocated to the space operation service under 1 GHz, are not suitable for the aforementioned applications, resolves 1 that administrations wishing to implement tracking, telemetry and command links for NGSO satellites with short duration missions are to use the bands indicated in considering d) above;

2 that the 137-138 MHz band requires the coordination of a space station in the space operation service (SOS) (space-to-Earth) with respect to terrestrial services (except for aeronautical mobile (OR) service networks operating in the administrations listed in No. 5.204 and 5.206) only when the pfd produced by the space station exceeds -125 dB (W/(m²  4 kHz)) on the Earth’s surface;

3 that the 137-138 MHz band requires the coordination of an SOS space station (space-to-Earth) with respect to the aeronautical mobile (OR) service only when the pfd produced by the space station on the Earth’s surface exceeds -140 dB (W/(m²  4 kHz)) in the administrations referred to in resolves 2, resolves further that use of the bands indicated in considering d) by NGSO satellites of the space operation service with short duration missions does not establish any priority in the Radio Regulations or prevent the use of this frequency band by any application of the services to which it is allocated.

NOTES: 1 It will be necessary to include resolves 1 in the relevant notes. 2 Suitable mechanisms are required to implement resolves 2 and 3.

Reasons: To provide coordination between space station in the SOS (space-to-Earth) with respect to terrestrial services and the aeronautical mobile (OR) service.

Document 4931 Resolution 359 (Rev.WRC-15) - Consideration of regulatory provisions for updating and modernization of the Global Maritime Distress and Safety System

Introduction Document 4891 Resolution 359, resolves to conduct studies, taking into consideration the activities of IMO, as well as information and requirements provided by IMO, in order to determine the regulatory provisions to support GMDSS modernization. The GMDSS modernization being considered under this agenda item focus on MF NAVDAT and HF NAVDAT.

Document 4841 WRC-19 agenda item 1.8 encompasses two separate items. The first is global maritime distress and safety system (GMDSS) modernization addressed under resolves to invite ITU-R 1 of Resolution 359 (Rev.WRC-15). In this Resolution, GMDSS modernization is referred to as “Issue A” and is addressed in this proposal The second is the introduction of additional satellite systems into the GMDSS, covered under resolves to invite ITU- R 2 of Resolution 359 (Rev.WRC-15). The introduction of an additional satellite system into the GMDSS is referred to as “Issue B” but is addressed separately.

The GMDSS was adopted as part of the 1988 amendments to the International Convention for the Safety of Life at Sea, 1974 (SOLAS). It was fully implemented in 1999. It has served the mariner and the maritime industry well since its inception, but some of the GMDSS technologies used have not reached their full potential, and some GMDSS functions could be performed by more modern technologies. The International Maritime Organization (IMO) has adopted a modernization plan for the GMDSS containing a high-level review and a detailed review. The detailed review and the plan show that the use of some existing analog services is declining while other new digital technologies are being introduced such as VHF data exchange system (VDES) and the NAVDAT system. The terrestrial component of VDES was previously addressed by WRC-15 and WRC-19 will consider the satellite component of VDES seperately under agenda item 1.9.2.

The used of navigational text (NAVTEX) was incorporated into the regulations for the GMDSS under Chapter V of the SOLAS regulations for disseminating maritime safety information. The ITU-R performed studies which resulted in the adoption of Recommendation ITU-R M.2010 “Characteristics of a digital system, named Navigational Data for broadcasting maritime safety and security related information from shore-to-ship in the 500 kHz band” and Recommendation ITU-R M.2058 “Characteristics of a digital system, named navigational data for broadcasting maritime safety and security related information from shore-to-ship in the maritime HF frequency band”. NAVDAT is considered as an enhancement of existing NAVTEX and could be considered as a potential replacement of NAVTEX as part of the continued modernization of the GMDSS.

Taking into account the studies performed during this study period under the resolves 1 of Resolution 359 (Rev.WRC-15) and noting the information and requirements provided by IMO, in order to determine the regulatory provisions to support GMDSS modernization, this proposal contains some regulatory provisions to facilitate the introduction of NAVDAT and progress the modernization of the GMDSS which will be further addressed at WRC-23 under Resolution 361 (Rev.WRC-15).

BACKGROUND Document 4891

19 CCPII-2019-33-4357_i 29.05.19

The CPM text contains three methods to address this agenda item. Method A1 proposes no change to the Radio Regulations (RR). Method A2 proposes to use frequency band 495-505 kHz for international MF NAVDAT, as well as modification to RR Appendix 17 to allow the use of HF NAVDAT. Method A3 is similar to Method A2 except that it adds the need for coordination and agreement to be obtained from affected administrations. Modification of RR Appendix 17 is required to allow the frequency bands described in the most recent version of Recommendation ITU-R M.2058 to be used for the HF NAVDAT system.

Document 4931

WRC-19 Agenda Item 1.8 encompasses two separate items. The first is global maritime distress and safety system (GMDSS) modernization addressed under resolves to invite ITU-R 1 of Resolution 359 (Rev.WRC-15), referred to as “Issue A” in the CPM report. The second is the introduction of an additional satellite system into the GMDSS. This is covered under resolves to invite ITU-R 2 of Resolution 359 (Rev.WRC-15), referred to as “Issue B” in the CPM report.

As regards Issue A, among the possible improvements of the GMDSS, frequency allocation to the data navigation system (NAVDAT) in the in HF and MF is currently under consideration.

IMO has adopted a modernization plan for the GMDSS containing a high-level review and a detailed review. The detailed review and the plan show that the use of some existing services is declining. Meanwhile, some new technologies are considered to be possibly introduced in the modernized GMDSS, such as VHF data exchange system (VDES) and the NAVDAT system.

Navigational text (NAVTEX) was incorporated into the regulations for the GMDSS for disseminating maritime safety information, which was introduced in a transitional phase from 1992 to 1999, after which it became mandatory under Chapter V of the SOLAS regulations.

NAVDAT is regarded as an improvement of the current NAVTEX and could be among the elements included in the next generation GMDSS.

WRC-12 addressed the allocation of the 495-505 kHz frequency band for the maritime mobile service. This band is regarded as the most suitable for MF NAVDAT application. However, regulatory provisions are still needed for both MF and HF NAVDAT applications.

NAVDAT may operate both in MF and HF. Since the 500 kHz frequency band provides good coverage as shown in Recommendation ITU-R P.368-9, the frequency band 415-526.5 kHz of the maritime mobile service would be used for MF NAVDAT as described in Recommendation ITU-R M.2010.

DISCUSSION Document 4891

Some administrations are of the view that MF NAVDAT may not be required due to the future implementation of VDES which will provide sufficient means to communicate the required navigational information in place of MF NAVDAT. However, the implementation of HF NAVDAT would complement data information in the Arctic region which would allow the distribution of detailed charts and maps for MSI in these areas

The following proposal is in line with Method A2 (no coordination is required). However, only the Appendix 17 implementation of the HF portion of the existing method is proposed.

20 CCPII-2019-33-4357_i 29.05.19

It is expected that by IMO will have completed its work on the modernization of GMDSS by 2023. An agenda item for WRC-23 is therefore being considered to address potential changes to Appendix 15.

Resolution 360 (Rev.WRC-15) – Consideration of regulatory provisions and spectrum allocations to the maritime mobile-satellite service to enable the satellite component of the VHF Data Exchange System and enhanced maritime radiocommunication

BACKGROUND

RESOLUTION 360 (REV. WRC-15) “Consideration of regulatory provisions and spectrum allocations to the maritime mobile-satellite service to enable the satellite component of the VHF Data Exchange System (VDES) and enhanced maritime radiocommunications”, invites ITU-R to conduct, as a matter of urgency, and in time for WRC-19, sharing and compatibility studies between VDES satellite components and incumbent services in the same and adjacent frequency bands specified in recognizing d) and e) to determine potential regulatory actions, including spectrum allocations to the MMSS (Earth-to-space and space-to-Earth) for VDES applications. To this end, the ITU-R has initiated sharing studies between the proposed VDES satellite (VDE- SAT) frequencies and the incumbent services in the same and adjacent bands so that this component does not impose any additional constraints on existing services in these and adjacent frequency bands as stated in recognizing d) and e) of Resolution 360 (Rev. WRC-15). The satellite component of the VDES could be beneficial towards enhancing maritime navigation and safety related applications on a global basis.

Traditional maritime communication methods (i.e. voice) have been used for the transfer of the information required to improve the safety of navigation particularly in adverse conditions. More information (such as weather, ice charts, status of aids to navigation, water levels and rapid changes of port status) is required in real- time to improve operational decisions on land and on ship that will lead to safer and more efficient voyages. Shore authorities have also demonstrated interest in increasing the quantity of information retrieved from ships in real-time (such as voyage information, passenger manifest and pre-arrival reports) in a more efficient way to transmit and process this information as digital information.

As a result of these additional requirements on maritime communications, WRC-15 made regulatory changes to Appendix 18 to facilitate the use of the terrestrial component of VHF Data Exchange system (VDES). These channels may be used by maritime authorities across the world to respond to increased data transfer and improve maritime safety and efficiency in the growing maritime environment. VDES is an extension of the very successful Automatic Identification System (AIS) used by the maritime community, while protecting the original function of AIS identification, position reporting and tracking.

AIS, designed primarily as a collision avoidance system, and application specific messages (ASM) will continue to operate along with the new VDES channels. VDES is based on robust and efficient digital transmission rates through the aggregation of several 25 kHz channels for increased throughput capacity. Once vessels have travelled outside the area of terrestrial coverage from shore stations, satellite networks could provide VDES capability to support and enhance safety and navigation. The satellite component of VDES is being further studied for WRC-19 to take into account existing services within and adjacent to the frequency band under consideration.

Under 5.225A, the adjacent frequency band 154-156 MHz includes a primary allocation to the radiolocation service in some countries.

Preliminary studies within ITU-R Working party 5B (WP 5B) concluded that compatibility between the radiolocation service and the maritime mobile satellite service (Earth-to-space) is feasible without imposing any

27 CCPII-2019-33-4357_i 29.05.19 additional constraints on the radiolocation service. Application of the radiolocation service in the frequency band 154-156 MHz is limited to the space surveillance radars.

Studies in WP 5B during the preparation for WRC-15, proposed a pfd mask for the maritime mobile satellite service to protect the incumbent fixed and mobile services.

Furthermore, the following three frequency plans have been studied in Report ITU-R M.2435-0. Note that only frequency plan alternatives 2 and 3 are used in the methods.

Frequency plan alternative 1 Frequency plan alternative 1 allow for utilization of the channels 24, 84, 25, 85, 26 and 86 of RR Appendix 18 in a shared manner between VDE-TER and VDE-SAT. - Four channels, 1024, 1084, 1025 and 1085, are shared between ship-to-shore and ship-to-satellite (VDE-SAT uplink) communications. - Two channels, 1026 and 1086, are exclusively reserved for ship-to-satellite (VDE-SAT uplink) services. - Four channels, 2024, 2084, 2025 and 2085, are shared among shore-to-ship, ship-to-ship and satellite- to-ship (VDE-SAT downlink) communications. - Two channels, 2026 and 2086, are exclusively reserved for satellite-to-ship (VDE-SAT downlink) communications and are not used for VDE-TER.

Frequency plan alternative 2 Frequency plan alternative 2 allows for utilization of channels 24, 84, 25 and 85 for VDE-TER, while channels 26 and 86 are identified for VDE-SAT uplink, and are not used for VDE-TER. VDE-SAT uplink is also possible in channels 24, 84, 25 and 85, but the VDE-SAT uplink on these channels should not impose constraints on VDE-TER. Frequencies are identified for VDE-SAT downlink within the frequency range 160.9625 MHz to 161.4875 MHz, which is not channelized in RR Appendix 18. - Four channels, 1024, 1084, 1025 and 1085, are identified for ship-to-shore communications, but ship- to-satellite (VDE-SAT uplink) may be possible without imposing constraints on ship-to-shore communications. - Four channels, 2024, 2084, 2025 and 2085, are identified for shore-to-ship and ship-to-ship communications, but ship-to-satellite (VDE-SAT uplink) may be possible without imposing constraints on shore-to-ship and ship-to-ship communications. - Two channels, 1026 and 2086, are exclusively reserved for ship-to-satellite (VDE-SAT uplink) services. - Frequencies are identified for satellite-to-ship (VDE-SAT downlink) services within the frequency range 160.9625 MHz to 161.4875 MHz, which is not channelized in RR Appendix 18.

Frequency plan alternative 3 Frequency plan alternative 3 allows for utilization of channels 24, 25 and 84, 85 in a shared manner between VDE-TER and VDE-SAT, while channels 26 and 86 are identified for VDE-SAT. - Four channels, 1024, 1084, 1025 and 1085, are shared between ship-to-shore, ship-to-ship, shore-to- ship and ship-to-satellite (VDE-SAT uplink) communications. - Two channels, 1026 and 2086, are identified for ship-to-satellite (VDE-SAT uplink) communications and are not used for VDE-TER. - Four channels, 2024, 2084, 2025 and 2085, are identified for satellite-to-ship (VDE-SAT downlink) communications, while the shore-to-ship communications may be possible without imposing constraints on satellite-to-ship communications. - The two channels 2026 and 2086, are identified for satellite-to-ship (VDE-SAT downlink) communications, and are not used for VDE-TER communications.

RESOLUTION 360 (REV. WRC-15) “Consideration of regulatory provisions and spectrum allocations to the maritime mobile-satellite service to enable the satellite component of the VHF Data Exchange System and enhanced maritime radiocommunications”, invites ITU-R to conduct, as a matter of urgency, and in time for WRC-19, sharing and compatibility studies between VDES satellite components and incumbent services in the same and adjacent frequency bands specified in recognizing d) and e) to determine potential regulatory actions, including spectrum allocations to the MMSS (Earth-to-space and space-to-Earth) for VDES applications.

WRC-15). The satellite component of the VDES could be beneficial towards enhancing maritime navigation and safety related applications on a global basis.

Under 5.225A, the adjacent frequency band 154-156 MHz includes a primary allocation to the radiolocation service in some countries.

Studies within ITU-R Working party 5B (WP 5B) concluded that compatibility between the radiolocation service and the maritime mobile satellite service (Earth-to-space) is feasible without imposing any additional constraints on the radiolocation service. Application of the radiolocation service in the frequency band 154-156 MHz is limited to the space surveillance radars.

Furthermore, WP5B completed a report, now published, Report ITU-R M.2435-2018 “Technical studies on the satellite component of the VHF data exchange system”, on the technical characteristics and feasibility assessment of the VDES satellite component.

EXECUTIVE SUMMARY

In accordance with Resolution 360 (Rev.WRC-15), the ITU-R has undertaken studies for possible new allocations to the maritime mobile-satellite service (MMSS) (Earth-to-space) and (space-to-Earth), preferably within the frequency bands 156.0125-157.4375 MHz and 160.6125-162.0375 MHz of RR Appendix 18, to support the digital evolution of maritime radio communications.

The results of the sharing and compatibility studies are contained in Recommendation ITU-R M.2092-0 which was developed in the WRC-15 study cycle, and Report ITU-R M.2435-0, which has been developed in this study cycle.

Based on the results of these studies, six methods have been developed to satisfy WRC-19 agenda item 1.9.2. The main differences between the methods are the frequency plan and pfd-mask to be imposed on the MMSS (space-to-Earth) emissions, which are further described in Report ITU-R M.2435-0.

THIS PROPOSAL

This proposal entails new primary allocations to the maritime mobile-satellite service (MMSS) (Earth-to-space) and (space-to-Earth), based on alternative frequency plan 2, with provisions for the optional use of the Appendix 18 duplex channels in simplex mode (in accordance with alternative frequency plan 3), as described in Report ITU-R M.2435-0. The coordination mechanism with respect to terrestrial services under RR No. 9.14 is proposed, with the pdf mask, for the satellite downlink.

[x] that, when deploying outdoor IMT base stations in the frequency bands 24.65-25.25 GHz and 27- 27.5 GHz , it shall be ensured that each antenna normally1 transmits only with the main beam pointing below the horizon and the antenna shall have mechanical pointing below the horizon except when the base station is only receiving. In addition, IMT base stations operating in these frequency bands shall comply with the e.i.r.p. density limits given in Table 1:

CCPII-2019-33-4357_i 29.05.19 60

Reasons: In spectrum shared with FSS (E-s), restrictions should be applied so that IMT BS antenna beams are ‘normally’ kept below the horizon in order to ensure protection of FSS space station receivers as the situation where BS antenna beams go above the horizon was not studied and this situation could increase the risk of interference. In addition, the maximum e.i.r.p. density of IMT BS operating in the same bands as FSS uplink should be limited to a level consistent with studies undertaken in TG 5/1 (i.e. greater than the input assumptions provided by ITU-R WP 5D by a number of dB based on the margin of protection found in the sharing studies performed by ITU-R TG 5/1) that provides maximum flexibility to IMT while still providing sufficient protection to space station receivers.

BACKGROUND

Mobile broadband plays a crucial and fundamental role in providing access to information for businesses and consumers worldwide. According to ITU statistics, mobile-broadband subscriptions have grown at more than 20 percent per year over the past five years, and it is expected that they will reach 4.3 billion worldwide by end 2017.1

Mobile broadband users are also demanding higher data rates and are using mobile devices to access audio-visual contents. The mobile industry continues to drive technological innovations in order to meet these evolving user demands. Research and development efforts from both industry as well as academia are facilitating the use of spectrum in bands above 6 GHz for mobile broadband. These efforts span the globe. Some countries and regions have also begun making spectrum available for mobile broadband applications in higher frequency bands in order to provide the benefits of these innovations to businesses and consumers worldwide.

The evolution of International Mobile Telecommunications (IMT), which provides wireless telecommunication services on a worldwide scale, has contributed to global economic and social development. IMT systems are now being evolved to provide applications such as enhanced mobile broadband, massive machine-type communications, and ultra-reliable and low-latency communications. Many of these applications will require larger contiguous blocks of spectrum than those available in the frequency bands currently identified for IMT. This has resulted in the need to address higher frequency bands to find these larger blocks of spectrum in the bands indicated in Resolution 238 (WRC-15).

In early 2012, ITU-R embarked on a program to develop “IMT for 2020 and beyond.” In November 2015, ITU-R approved Recommendation ITU-R M.2083 “IMT Vision – Framework and overall objectives of the future development of IMT for 2020 and beyond,” which highlights three trends in future IMT-2020 systems: communications at very high data speeds, numerous connected devices, and ultra-reliable and low-latency communications.

The success of these trends, in both developed and developing countries, will rely on both spectrum availability for the terrestrial IMT-2020 systems and the support of high-capacity backhaul capabilities (including fiber, wireless, satellite, and microwave solutions). Recognizing the need to consider the spectrum in the range 24.25 to 86 GHz to support the terrestrial component of IMT in higher frequency

CCPII-2019-33-4357_i 29.05.19 61 bands, while protecting existing services, World Radiocommunication Conference (WRC) 2015 approved WRC-19 agenda item 1.13.

The central topic is the need to conceive, from the outset, high frequency bands that are harmonized enough to foster economies of scale and meet the short-, medium- and long-term spectrum requirements, and to incorporate the use of new technologies that can benefit from the physical features of various frequency ranges, whose bandwidths would enable lower latencies and higher transmission rates for the transmission and exchange of mobile data.

Beyond the results of the last WRC-15, the challenge for the future is now to focus efforts on the 24.25 GHz to 86 GHz frequency range. This is a great opportunity to meet the technical and spectral needs for the future development of IMT-2020 systems, better known as 5G.

WRC-19 agenda item 1.13 (Resolution 238 (WRC-15)) decided to study candidate frequency bands in portion(s) of the frequency range between 24.25 and 86 GHz so as the assess the viability of their identification for the development of next-generation IMT systems. In order to better understand the situation in the Americas region with respect to this agenda item, a “Questionnaire on Usage and Future Plan of Frequency Bands Under Study in Agenda Item 1.13 of WRC-19, in Americas Region” (Decision CCP.II/DEC. 183 (XXVII-16) was proposed. By and at the 29 Meeting of PCC.II, responses from eight administrations were received and the answers were compiled in document (CCP.II- RADIO/doc.4310/17).

The main issue is the need to conceive, from the start, high frequency bands with sufficient harmonization to encourage economies of scale and meet the spectrum needs in the short, medium and long term, and to mainstream the use of new technologies that benefit from physical characteristics in different frequency ranges, whose bandwidths would allow lower latencies and higher rates for mobile data transmission and exchange.

CCPII-2019-33-4357_i 29.05.19 74 Agenda Item 1.13: to consider identification of frequency bands for the future development of International Mobile Telecommunications (IMT), including possible additional allocations to the mobile service on a primary basis, in accordance with Resolution 238 (WRC-15);

BACKGROUND

The evolution of International Mobile Telecommunications (IMT), which provides wireless telecommunications services on a global scale, has contributed to global economic and social development. IMT systems are now evolving to offer applications such as enhanced mobile broadband communications, mass machine communications and ultra-reliable, low-latency communications. Many of these applications will require contiguous blocks of spectrum greater than those available in the frequency bands that are currently identified for IMT. As a result, higher frequency bands must be considered in order to identify such higher spectrum blocks in the bands indicated via Resolution 238 (WRC-15).

In early 2012, the ITU-R undertook a program to develop “IMT for 2020 and beyond.” In November 2015, ITU-R adopted Recommendation ITU-R M.2083 with the “IMT Vision – Framework and overall objectives of the future development of IMT for 2020 and beyond," which highlights three trends for future IMT-2020 systems: communications at very high data rates, numerous connected devices with low latency applications, and high reliability.

The success of these trends, both in developed and developing countries, will depend both on the availability of spectrum for IMT-2020 terrestrial systems and on the support of high capacity back haul capabilities (including fiber optics, wireless, satellite, and microwave). Recognizing the need to consider the spectrum between 24.25 and 86 GHz to support the terrestrial component of IMT in higher frequency bands while protecting existing services, point 1.13 of WRC-19 was adopted by the 2015 World Radio Communication (WRC) Conference.

The main issue is the need to conceive, from the start, high frequency bands with a sufficient harmonization to encourage economies of scale and meet the spectrum needs in the short, medium and long term, and to mainstream the use of new technologies that benefit from physical characteristics in different frequency ranges, whose bandwidths would allow lower latencies and higher rates for mobile data transmission and exchange.

CCPII-2019-33-4357_i 29.05.19 75 Beyond the results obtained in the last WRC-15, the challenge for the future is to focus efforts in the 24.25-86 GHz frequency band, which poses a magnificent opportunity to meet the technical and spectral requirements for the future development of IMT-2020 systems, better known as 5G.

WRC-19 agenda item 1.13 (Resolution 238 (WRC-15)) decided to study candidate frequency bands in one or more parts of the frequency range 24.25-86 GHz to assess the feasibility of identifying them for developing next-generation IMT systems. In order to better understand the situation in the region of the Americas with respect to this agenda item, a questionnaire on the use of and future plans for the frequency bands under study per WRC-19 agenda item 1.13 - Americas Region was proposed (decision PCC.II/DEC. 183 (XXVII-16)). Before and during the 29th CCP.II meeting, responses were received from eight administrations and compiled in document CCP.II-RADIO/doc.4310t/17).

BACKGROUND

The aim of 5G is to create a more ‘hyper connected’ society by more comprehensively, and intelligently, integrating LTE, Wi-Fi and cellular IoT technologies, together with at least one new 5G radio interface. This will allow mobile networks to dynamically allocate resources to support the varying needs of a hugely diverse set of connections – ranging from industrial machinery in factories, to automated vehicles as well as smartphones. The significant extra capacity of the 5G radio network will need to be supported with higher bandwidth backhaul, including fibre and microwave networks. Satellite networks should also be considered for 5G backhaul while noting their limited ability to satisfy 5G’s expected latency and bandwidth requirements

A central component in the evolution of all mobile technology generations has been the use of increasingly wide frequency bands to support higher speeds and larger amounts of traffic. 5G is no different, ultra-fast 5G services will require large amounts of spectrum including above 24 GHz where wide bandwidths are more readily available. Without making these higher frequency bands available for 5G, it may not be possible to deliver a step-change in mobile broadband speeds and support rapidly growing mobile data traffic, especially in busy urban areas.

Spectrum above 24 GHz is well recognized worldwide as being the key component for the fastest 5G services. Without them, 5G won’t be able to deliver significantly faster data speeds or support projected extensive mobile traffic growth.

BACKGROUND

Agenda Item 1.14 was adopted by WRC-15 to consider, in accordance with Resolution 160 (WRC-15), regulatory actions that can facilitate deployment of HAPS for broadband applications. Resolution 160 resolves to invite ITU-R to study additional spectrum needs of HAPS, examining the suitability of existing HAPS designations and conducting sharing and compatibility studies for additional designations in existing fixed allocations in the 38-39.5 GHz band on a global basis and in 21.4-22 GHz and 24.25- 27.5 GHz bands in Region 2.

Currently, there are 3 spectrum bands identified for HAPS in the fixed services. These are: - 47.2–47.5 GHz and 47.9 48.2 GHz, - 27.9-28.2 GHz (HAPS-ground) and 31.0-31.3 GHz (ground-HAPS) - 6 440–6 520 MHz (HAPS-ground) and 6 560-6 640 MHz (ground-HAPS).

While the use of the bands 6 440–6 520 MHz (HAPS-ground) and 6 560-6 640 MHz (ground-HAPS) are permitted in a number of countries via footnote 5.457, none of these countries are within Region 2.

BACKGROUND

No. 1.66A of the ITU Radio Regulations defines a high-altitude platform station (HAPS) as "a station on an object at an altitude of 20 to 50 km and at a specified, nominal, fixed point relative to the Earth". Agenda Item 1.14 was adopted by WRC-15 to consider, in accordance with Resolution 160 (WRC-15), regulatory actions that can facilitate deployment of HAPS for broadband applications. Resolution 160 resolves to invite ITU-R to study additional spectrum needs of HAPS, examining the suitability of existing HAPS designations and conducting sharing and compatibility studies for additional designations in existing fixed allocations in the 38-39.5 GHz band on a global basis and in 21.4-22 GHz and 24.25- 27.5 GHz bands in Region 2 exclusively.

Advances in aeronautics and transmission technologies have significantly improved the capabilities of HAPS to provide effective connectivity solutions and meet the growing demand for high capacity broadband networks, particularly in currently underserved areas. Recently conducted full-scale test flights have shown that solar-powered platforms in the upper-atmosphere can now be used to carry payloads that offer reliable and cost-effective connectivity, and a growing number of applications for the new generation of HAPS are being developed. The technology appears particularly well suited to complementing terrestrial networks by providing backhaul. A number of advantages of the new generation of HAPS are foreseen:

 Geographical reach: HAPS that use the architecture of solar platforms can also provide connectivity where it is impossible to deploy terrestrial infrastructure: remote sites on land or sea.  Wide-area coverage: Depending on the operational scenario, a single platform is capable of providing footprints on the order of up to100 km in diameter, and recent technological advances in the development of optical inter-HAPS links now support the deployment of multiple linked HAPS, in fleets that can provide greater coverage within a country as needed.  Low cost and Environmental aspects: The cost of operating stratospheric platforms is projected to be lower than other connectivity solutions depending on geographical area, while mass production of the aircraft will significantly lower upfront capital expenditure for deployment. HAPS can run exclusively on solar power for long periods, connecting people with almost no environmental impact.

 Rapid deployment and flexibility: It may be possible to deploy HAPS services without long lead times and it is relatively simple to return solar platforms to the ground for maintenance or payload reconfiguration.

ITU members have conducted compatibility studies to assess coexistence between HAPS and incumbent FS, EESS and RAS services. Associated regulatory provisions are proposed below based on the results of sharing studies. In addition, the limitation of the use of HAPS to the HAPS-to-ground direction is to ensure the protection of EESS passive services.

CCPII-2019-33-4357_i 29.05.19 89 Agenda Item 1.14: to consider, on the basis of ITU-R studies in accordance with Resolution 160 (WRC- 15), appropriate regulatory actions for high-altitude platform stations (HAPS), within existing fixed- service allocations

BACKGROUND

No. 1.66A of the ITU Radio Regulations defines a high-altitude platform station (HAPS) as "a station on an object at an altitude of 20 to 50 km and at a specified, nominal, fixed point relative to the Earth". Agenda Item 1.14 was adopted by WRC-15 to consider, in accordance with Resolution 160 (WRC-15), regulatory actions that can facilitate deployment of HAPS for broadband applications. Resolution 160 (WRC-15) resolves to invite ITU-R to study additional spectrum needs of HAPS, examining the suitability of existing HAPS designations and conducting sharing and compatibility studies for additional designations in existing fixed allocations in the 38-39.5 GHz band on a global basis and in 21.4-22 GHz and 24.25-27.5 GHz bands in Region 2 exclusively.

The ITU-R is conducting compatibility studies to assess coexistence between HAPS and incumbent and proposed systems and services (including issues of overlap with WRC-19 Agenda Items 1.6 and 1.13). Associated regulatory provisions are proposed below based on the results of sharing studies. The limitation of the use of HAPS in the ground-to-HAPS direction in the FSS (E-s) allocated frequency bands 27-27.5 GHz is to ensure the protection of FSS (E-s) services. In addition, the reason for the

CCPII-2019-33-4357_i 29.05.19 90 limitation of the use of HAPS in the ground-to-HAPS direction in the 25.5-27 GHz band is to ensure the protection of EESS/SRS services operating in this band.

The band 24.25 – 25.25 is proposed as “no change” as Resolution 160 (WRC-15) calls for identifications for HAPS in frequency bands already allocated to the fixed service on a primary basis. In Region 2, these bands are not allocated to the fixed service.

BACKGROUND No. 1.66A of the ITU Radio Regulations defines a high-altitude platform station (HAPS) as "a station on an object at an altitude of 20 to 50 km and at a specified, nominal, fixed point relative to the Earth". Agenda Item 1.14 was adopted by WRC-15 to consider, in accordance with Resolution 160 (WRC-15), regulatory actions that can facilitate deployment of HAPS for broadband applications. Resolution 160 (WRC-15) resolves to invite ITU-R to study additional spectrum needs of HAPS, examining the suitability of existing HAPS designations and conducting sharing and compatibility studies for additional designations in existing fixed allocations in the 38-39.5 GHz band on a global basis and in 21.4-22 GHz and 24.25-27.5 GHz bands only in Region 2. Resolution 160 (WRC-15) also states that existing services and their applications shall be protected from HAPS applications, and no undue constraints shall be imposed on the future development of existing services by HAPS. Spectrum harmonization and utilization is facilitated by common worldwide designations. International regulatory flexibility can enable improvements in global connectivity by encouraging national regulators to permit operation of higher-speed Internet access services over new, complementary platforms, while ensuring protection of existing services. Additionally, harmonization of spectrum promotes economies of scale and commonality of equipment.

BROADBAND HAPS APPLICATIONS Advances in aeronautics and transmission technologies have significantly improved the capabilities of HAPS to provide effective connectivity solutions and meet the growing demand for high capacity broadband networks, particularly in currently underserved areas. Recently conducted full-scale test flights have shown that solar-powered platforms in the upper-atmosphere can now be used to carry payloads that offer connectivity over large areas in a reliable and cost-effective way, and a growing number of applications for the new generation of HAPS are being developed. The technology appears particularly well suited to complementing terrestrial networks by providing backhaul. A number of advantages of the new generation of HAPS are foreseen:  Reach: HAPS platforms may operate at around 20 km above ground, which reduces their vulnerability to weather conditions that may affect service, provides large coverage areas and helps mitigate interference caused by physical obstacles.

CCPII-2019-33-4357_i 29.05.19 103  Rapid deployment and flexibility: It may be possible to deploy HAPS services without long lead times and it is relatively simple to return solar platforms to the ground for maintenance or payload reconfiguration.

Broadband HAPS can also be used for response to natural disasters, fire detection, monitoring, and firefighting, law enforcement, and resource exploration missions. ITU-R STUDIES The ITU-R developed a preliminary draft new Recommendation (PDNR) assessing spectrum needs for broadband HAPS, which concludes “These assumed system characteristics show that the spectrum needs for HAPS are in the range from 396 MHz to 2 969 MHz for the uplink and 324 MHz to 1 505 MHz for downlink, for both GW and CPE links, which would need to be considered within existing and/or new HAPS designations. These ranges include the spectrum needs to cover those of specific applications (e.g., disaster relief missions) plus that for connectivity applications (e.g., commercial broadband).” A number of ITU-R sharing and compatibility studies have been conducted to assess coexistence between HAPS and incumbent and proposed systems and services (including WRC-19 Agenda Items 1.6 and 1.13). To facilitate sharing in cross-border areas with other concerned countries, Power-flux density (PFD) masks are proposed to ensure the protection of the fixed and mobile services from downlink emissions by HAPS platforms (HAPS-to-ground), which if exceeded would require explicit agreement from affected administrations. However, these studies have not yet concluded.

These proposals provide appropriate RR footnotes and associated resolutions to facilitate the use of HAPS links on a global level, limited to the currently identified frequency bands taking into account the requisite protections for those incumbent services in the band.

CCPII-2019-33-4357_i 29.05.19 108 Agenda Item 1.14: to consider, on the basis of ITU-R studies in accordance with Resolution 160 (WRC- 15), appropriate regulatory actions for high-altitude platform stations (HAPS), within existing fixed- service allocations

BACKGROUND

No. 1.66A of the ITU Radio Regulations defines a high-altitude platform station (HAPS) as "a station on an object at an altitude of 20 to 50 km and at a specified, nominal, fixed point relative to the Earth". Agenda Item 1.14 was adopted by WRC-15 to consider, in accordance with Resolution 160 (WRC-15), regulatory actions that can facilitate deployment of HAPS for broadband applications. Resolution 160 (WRC-15) resolves to invite ITU-R to study additional spectrum needs of HAPS, examining the suitability of existing HAPS designations and conducting sharing and compatibility studies for additional designations in existing fixed allocations in the 38-39.5 GHz band on a global basis and in 21.4-22 GHz and 24.25-27.5 GHz bands in Region 2 exclusively.

The following frequency bands have been designated for HAPS in the fixed services: - 47.2–47.5 GHz and 47.9 48.2 GHz, - 27.9-28.2 GHz (HAPS-ground) and 31.0-31.3 GHz (ground-HAPS) - 6 440–6 520 MHz (HAPS-ground) and 6 560-6 640 MHz (ground-HAPS).

Advances in aeronautics and transmission technologies have significantly improved the capabilities of HAPS to provide effective connectivity solutions and meet the growing demand for high capacity broadband networks, particularly in currently underserved areas. Recently conducted full-scale test flights have shown that solar-powered platforms in the upper-atmosphere can now be used to carry payloads that offer connectivity over large areas in a reliable and cost-effective way, and a growing number of applications for the new generation of HAPS are being developed. The technology appears particularly well suited to complementing terrestrial networks by providing backhaul. A number of advantages of the new generation of HAPS are foreseen:

 Reach: HAPS platforms may operate at around 20 km above ground, which reduces their vulnerability to weather conditions that may affect service, provides large coverage areas and helps mitigate interference caused by physical obstacles.  Geographical reach: HAPS that use the architecture of solar platforms can also provide connectivity where it is impossible to deploy terrestrial infrastructure: remote sites on land or sea.  Wide-area coverage: Depending on the operational scenario, a single platform is capable of providing footprints on the order of up to100 km in diameter, and recent technological advances in the development of optical inter-HAPS links now support the deployment of multiple linked HAPS, in fleets that can provide greater coverage within a country as needed.  Low cost and Environmental aspects: The cost of operating stratospheric platforms is projected to be lower than other connectivity solutions depending on geographical area, while mass production of the aircraft will significantly lower upfront capital expenditure for deployment. HAPS can run exclusively on solar power for long periods, connecting people with almost no environmental impact.  Rapid deployment and flexibility: It may be possible to deploy HAPS services without long lead times and it is relatively simple to return solar platforms to the ground for maintenance or payload reconfiguration.

ITU members have conducted compatibility studies to assess coexistence between HAPS and incumbent services. Associated regulatory provisions were originally established in Resolution 122 (Rev.WRC-07)

CCPII-2019-33-4357_i 29.05.19 109 but did not include protections for the mobile service. These changes are proposed below based on the results of sharing studies.

Brazil

BACKGROUND

The band 5 150-5 250 MHz is allocated to different co-primary services in the RR Table of Allocations, including Fixed Satellite Service (FSS - uplink), Aeronautical Radionavigation Service (ARNS) and Mobile. Therefore, potential WAS/RLAN use in 5 150-5 250 MHz cannot impose constraints on other services to which the band is allocated.

In Brazil, the frequency band 5 150 - 5 250 MHz is essential for future aeronautical telemetry transmissions, flight tests safety, and evaluation and aeronautical industry development; and, in this context the aeronautical mobile service for telemetry should have priority over other uses by another services. Moreover, it is important to consider Aeronautical Radionavigation service in this band; that there is a provision for using this band for military purposes, including information download, whose transmission characteristics are similar to those from aeronautical telemetry.

One study carried out in the ITU-R WP 5A indicated that outdoor usage with the e.i.r.p. values recognized in Resolution 229 (Rev.WRC-12) cannot ensure the coexistence of outdoor RLANs and the aeronautical mobile telemetry (AMT). This study also showed that AMT systems can have the same level of protection established by Resolution 229 (Rev.WRC-12), when combining a low e.i.r.p. (up to 40 mW) with in-vehicle use. However, without development and implementation of such measures for reducing the interference the decision of possible outdoor WAS/RLAN systems usage in the considered frequency band cannot be made. Therefore, this solution is considered as an extremely difficult mitigation technique to allow sharing between WAS/RLAN and AMT.

Related to ARNS, one study carried out in the ITU-R WP 5A indicated that the effective measures for reducing interference for airborne sense and avoid systems operation are to be developed to enable the usage of outdoor WAS/RLAN in the 5 150 - 5 250 MHz frequency band. Another study is showed that if the number of outdoor RLANs is limited, and the distance between RLANs and ARNS systems is larger than a specific protection distance, the total interference level from RLANs is lower than the threshold for ARNS systems. However, this solution is considered as an difficult mitigation technique to allow sharing between WAS/RLAN and ARNS. Another (MCL) coexistence study, showed that an outdoor RLAN relaxation without any mitigation technique would cause harmful interference to the ARNS, but it was shown that the same level of protection offered by the indoor usage is achieved when combining a low e.i.r.p. of 40 mW and a restricted in-vehicle use for the outdoor case. Once more, without development and implementation of such measures for reducing the interference the decision of possible outdoor WAS/RLAN systems usage in the considered frequency band cannot be made.

As such, NOC is indicated by Brazilian Administration for this frequency band in agenda item 1.16, since there will be extremely difficult to find mitigation techniques to facilitate sharing between outdoor RLAN and aeronautical telemetry transmission, which is used for safety and military purposes in Brazil.

BACKGROUND

Radio Local Area Networks (RLANs) have proven to be a tremendous success in providing affordable and ubiquitous broadband connectivity. Introduced by some administrations in limited spectrum in the 2.4 GHz band and subsequently expanded into the 5 GHz band, RLANs, specifically Wi-Fi devices, now are an integral component of the world’s connectivity infrastructure. According to the latest statistics, more than 50% of all global IP traffic will be delivered over Wi-Fi4, and forecasts suggest that with the introduction of 5G and gigabit wireless technologies, the demand will continue to grow rapidly in the coming years. In spite of the growing demand, however, the spectrum available globally for RLAN access has remained unchanged since World Radiocommunication Conference 2003 (WRC-03). This lack of adequate spectrum threatens to degrade RLAN performance and limit connectivity for consumers worldwide. This problem is particularly acute for RLAN outdoor deployments.

The 5 150 – 5 250 MHz band offers unique advantages in addressing the growing need for RLAN outdoor access. In 2017, Canada authorized the use of higher power RLAN devices, both indoor and outdoor, in the 5 150-5 250 MHz frequency band under a licensed regime. In particular, these regulations have promoted RLAN use of this band in co-existence with mobile-satellite-service (MSS) operations through

CCPII-2019-33-4357_i 29.05.19 117 E.I.R.P. limitations at higher antenna elevation angles. These rules generally permit indoor and outdoor RLAN operations in the 5 150 – 5 250 MHz band at up to 1 Watt conducted or 4 Watt E.I.R.P., except that operations with antenna elevation angles in excess of 30 degrees from the horizon must not exceed 5,6 125 mW E.I.R.P. These rules are intended to prevent harmful interference to MSS Earth-to-space communications by limiting the aggregate noise received by the satellite.

In addition, rules were put in place to ensure that any unwanted emissions from the 5 150-5 250 MHz frequency band that fall into the 5 250-5 350 MHz band shall be attenuated below the channel power by at least 26 dB; this is to provide clarity and promote coexistence with operations of incumbent services, in particular the EESS allocation, in the 5 250-5 350 MHz band.

The proposal below establishes an international regulatory framework that will enable much-needed RLAN outdoor deployments while ensuring protection of other operations in the 5 150-5 250 MHz band and clarity on out-of-band emissions into the 5 250-5 350 MHz band.

Administrations are requested to take appropriate measures that will result in the predominant number of stations in the mobile service being operated in an indoor environment. Furthermore, stations in the mobile service that are permitted to be used either indoors or outdoors may operate up to a maximum mean e.i.r.p. of 1 W and a maximum mean e.i.r.p. density of 50 mW/MHz in any 1 MHz band, and, when operating above a mean e.i.r.p. of 200 mW, these stations shall comply with the following e.i.r.p. elevation angle mask where  is the angle above the local horizontal plane (of the Earth): −13 dB(W/MHz) for 0° ≤  < 8 −13 − 0.716( − 8) dB(W/MHz) for 8° ≤  < 40 −35.9 − 1.22( − 40) dB(W/MHz) for 40° ≤  ≤ 45 −42 dB(W/MHz) for 45° < ; 54 that administrations may exercise some flexibility in adopting other mitigation techniques, provided that they develop national regulations to meet their obligations to achieve an equivalent level of protection to the EESS (active) and the SRS (active) based on their system characteristics and interference criteria as stated in Recommendation ITU-R RS.1632; 65 that in the band 5 470-5 725 MHz, stations in the mobile service shall be restricted to a maximum transmitter power of 250 mW32 with a maximum mean e.i.r.p. of 1 W and a maximum mean e.i.r.p. density of 50 mW/MHz in any 1 MHz band; 76 that in the bands 5 250-5 350 MHz and 5 470-5 725 MHz, systems in the mobile service shall either employ transmitter power control to provide, on average, a mitigation factor of at least 3 dB on the maximum average output power of the systems, or, if transmitter power control is not in use, then the maximum mean e.i.r.p. shall be reduced by 3 dB; 87 that, in the bands 5 250-5 350 MHz and 5 470-5 725 MHz, the mitigation measures found in Annex 1 to Recommendation ITU-R M.1652-1 shall be implemented by systems in the mobile service to ensure compatible operation with radiodetermination systems, invites administrations to adoptconsider appropriate regulation if they intend to permitmeasures when allowing the operation of stations in the mobile service using the e.i.r.p. elevation angle mask referred in resolves 43 above, to ensure the equipment is operated in compliance with this mask, invites ITU-R 1 to continue work on regulatory mechanisms and further mitigation techniques to avoid incompatibilities which may result from aggregate interference into the FSS in the band 5 150-5 250 MHz from a possible prolific growth in the number of WAS, including RLANs;

CCPII-2019-33-4357_i 29.05.19 121 21 to continue studies on mitigation techniques to provide protection of EESS from stations in the mobile service,; 32 to continue studies on suitable test methods and procedures for the implementation of dynamic frequency selection, taking into account practical experience.

Reasons: The band 5 150-5 250 MHz is the only worldwide harmonized spectrum for RLANs in the 5 GHz range that is not subject to the dynamic frequency selection constraint. Some studies confirm that RLAN operations outdoors in the band 5 150-5 250 MHz will not cause harmful interference to other operations in the band. The results of these studies are further confirmed by the real-world operational experience with some countries allowing RLAN operations outdoors in the 5 150-5 250 MHz with appropriate constraints, e.g. maximum number of outdoor RLANs. Allowing RLAN access to outdoor use in the band 5 150-5 250 MHz with appropriate technical rules would address the growing demand for continuous and ubiquitous connectivity.

Agenda Item Vice-Rapporteur: TBD

CCPII-2019-33-4357_i 29.05.19 123 Agenda Item 1.16: to consider issues related to wireless access systems, including radio local area networks (WAS/RLAN), in the frequency bands between 5 150 MHz and 5 925 MHz, and take the appropriate regulatory actions, including additional spectrum allocations to the mobile service, in accordance with Resolution 239 (WRC-15).

BACKGROUND

Since WRC-03, the demand for mobile broadband applications especially for WAS/RLANs has been growing rapidly. Resolution 239 (WRC-15) states “that the results of ITU-R studies indicate that the minimum spectrum need for WAS/RLAN in the 5 GHz frequency range in the year 2018 is estimated at 880 MHz; this figure includes 455-580 MHz already utilized by non-IMT mobile broadband applications operating within the 5 GHz range resulting in 300-425 MHz additional spectrum being required.” In particular, Resolution 239 (WRC-15) looks at studying possible RLAN operations in the frequency bands from 5 150-5 925 MHz.

Reasons: There is a footnote (5.453) with the additional attribution on a primary basis for the mobile service, so some countries have deployed applications using WAS/RLAN technologies operating at various power levels using various mitigation techniques for coexistence between services involved in this band. In other countries, the allocation to the mobile service on a secondary basis has been adopted.

CCPII-2019-33-4357_i 29.05.19 126 Agenda Item 2: to examine the revised ITU-R Recommendations incorporated by reference in the Radio Regulations communicated by the Radiocommunication Assembly, in accordance with Resolution 28 (Rev.WRC-15), and to decide whether or not to update the corresponding references in the Radio Regulations, in accordance with the principles contained in Annex 1 to Resolution 27 (Rev.WRC-12);

INTRODUCTION Resolution 27 instructs the Director of the Radiocommunication Bureau to identify the provisions and footnotes of the Radio Regulations (RR) containing references to ITU-R Recommendations, as well as the provisions and footnotes of the RR containing references to WRC Resolutions that contain references to ITU-R Recommendations, and make suggestions on any further action to the second session of the Conference Preparatory Meeting (CPM) for its consideration. Furthermore, the Resolution 28 (Rev.WRC- 15) “Revision of references to the text of ITU-R Recommendations incorporated by reference in the Radio Regulations” instructs the Director of the Radiocommunication Bureau to provide the CPM immediately preceding each WRC with a list, for inclusion in the CPM Report, of those ITU-R Recommendations containing texts incorporated by reference that have been revised or approved since the previous WRC, or that may be revised in time for the following WRC.

Based on the above, in CPM 19-2 a proposal was made to combine Resolutions 27 and 28, considering that there are cross references in both Resolutions and that the paragraphs under the headings «instructs the Radiocommunication Director» are presented in the Resolutions separately. The proposal was included in Chapter 6 of the CPM Report 19-2.

The combination proposal would make it possible to streamline the work of the Radiocommunication Bureau and the Administrations.

PROPOSAL

Mexico presents in ANNEX 1 a Preliminary Proposal related to Agenda Item 2 of WRC-19 for consideration by the Administrations during the process the preparing for the WRC-19.

NOTE: Document not translated by the Secretariat of CITEL.

CCPII-2019-33-4357_i 29.05.19 127 The Preliminary Proposal consists in supporting the combination of Resolutions 27 and 28, modifying Resolution 27 so that it becomes the combination of Resolutions 27 and 28, taking into account that its necessary to have two separate paragraphs, respectively, under the epigraphs “resolves” and “further resolves”. The foregoing, derived from the 2018 Plenipotentiary Conference (PP-18), invited the Member States, Conferences and Assemblies to support the principle of streamlining resolutions to avoid repetition. In view of the above, the examination of the Administrations is facilitated to evaluate the incorporation of the ITU-R Recommendations in the RR that meet the established criteria.

RESOLUTION 27 (REV.WRC-1219)

Use of incorporation by reference in the Radio Regulations

The World Radiocommunication Conference (GenevaSharm el-Sheikh, 20122019), considering a) that the Voluntary Group of Experts (VGE) on simplification of the Radio Regulations proposed the transfer of certain texts of the Radio Regulations to other documents, especially to ITU-R Recommendations, using the incorporation by reference procedure; ab) that the principles of incorporation by reference were adopted by WRC-95 and revised by subsequent conferences (see Annexes 1 and 2 to this Resolution); bc) that, in some cases, there are provisions in the Radio Regulations containing references which fail to distinguish adequately whether the status of the referenced text is mandatory or non-mandatory; ed) that all texts of ITU-R Recommendations incorporated by reference are published in a volume of the Radio Regulations;

fe) that, taking into account the rapid evolution of technology, ITU-R may revise the ITU-R Recommendations containing text incorporated by reference at short intervals;

gf) that, following revision of an ITU-R Recommendation containing text incorporated by reference, the reference in the Radio Regulations shall continue to apply to the earlier version until such time as a competent world radiocommunication conference (WRC) agrees to incorporate the new version hg) that it would be desirable that texts incorporated by reference reflect the most recent technical developments, noting a) that references to Resolutions or Recommendations of a world radiocommunication conference (WRC) require no special procedures, and are acceptable for consideration, since such texts will have been agreed by a WRC,; b) that administrations need sufficient time to examine the potential consequences of changes to ITU-R Recommendations containing text incorporated by reference and would therefore benefit greatly

5 that texts which are of a non-mandatory nature or which refer to other texts of a non-mandatory nature shall not be considered for incorporation by reference;

26 that when considering the introduction of new cases of incorporation by reference, such incorporation shall be kept to a minimum and made by applying the following criteria: 6.1 only texts which are relevant to a specific WRC agenda item may be considered; – the correct method of reference shall be determined on the basis of the principles set out in Annex 1 to this Resolution; 6.2 where the relevant texts are brief, the referenced material should be placed in the body of the Radio Regulations rather than using incorporation by reference; 6.3 the guidance contained in Annex 21 to this Resolution shall be applied in order to ensure that the correct method of reference for the intended purpose is employed; 37 that the text of the incorporation by reference must be submitted for adoption by a competent WRC and the procedure described in Annex 32 to this Resolution shall be applied for approving the incorporation by reference of ITU-R Recommendations or parts thereof;

48 that existing references to ITU-R Recommendations shall be reviewed to clarify whether the reference is mandatory or non-mandatory in accordance with Annex 21 to this Resolution;

59 that ITU-R Recommendations, or parts thereof, incorporated by reference at the conclusion of each WRC, and a cross-reference list of the regulatory provisions, including footnotes and Resolutions, incorporating such ITU-R Recommendations by reference, shall be collated and published in a volume of the Radio Regulations (see Annex 32 to this Resolution),;

10 that if, between WRCs, a text incorporated by reference (e.g. an ITU-R Recommendation) is updated, the reference in the Radio Regulations shall continue to apply to the earlier version incorporated by reference until such time as a competent WRC agrees to incorporate the new version; the mechanism for considering such a step is given in further resolves part of this Resolution, further resolves

CCPII-2019-33-4357_i 29.05.19 130 . ANNEX 1 TO RESOLUTION 27 (Rev.WRC-12)

Principles of incorporation by reference

1 For the purposes of the Radio Regulations, the term “incorporation by reference” shall apply only to those references intended to be mandatory. 2 Where the relevant texts are brief, the referenced material should be placed in the body of the Radio Regulations rather than using incorporation by reference. 3 Where a mandatory reference to an ITU-R Recommendation, or parts thereof, is included in the resolves of a WRC Resolution, which is itself cited in a provision or footnote of the Radio Regulations using mandatory language (i.e. “shall”), that ITU-R Recommendation or parts thereof shall also be considered as incorporated by reference. 4 Texts which are of a non-mandatory nature or which refer to other texts of a non-mandatory nature shall not be considered for incorporation by reference. 5 If, on a case-by-case basis, it is decided to incorporate material by reference on a mandatory basis, then the following provisions shall apply: 5.1 the text incorporated by reference shall have the same treaty status as the Radio Regulations themselves; 5.2 the reference must be explicit, specifying the specific part of the text (if appropriate) and the version or issue number; 5.3 the text incorporated by reference must be submitted for adoption by a competent WRC in accordance with resolves 3; 5.4 all texts incorporated by reference shall be published following a WRC, in accordance with resolves 5. 6 If, between WRCs, a text incorporated by reference (e.g. an ITU-R Recommendation) is updated, the reference in the Radio Regulations shall continue to apply to the earlier version incorporated by reference until such time as a competent WRC agrees to incorporate the new version. The mechanism for considering such a step is given in Resolution 28 (Rev.WRC-03)*.

ANNEX 21 TO RESOLUTION 27 (REV.WRC-1219)

Application of incorporation by reference

When introducing new cases of incorporation by reference in the provisions of the Radio Regulations or reviewing existing cases of incorporation by reference, administrations and ITU-R should address the following factors in order to ensure that the correct method of reference is employed for the intended purpose, according to whether each reference is mandatory (i.e. incorporated by reference), or non-mandatory: Mandatory references 1 mandatory references shall use clear linking language, i.e. “shall”; 2 mandatory references shall be explicitly and specifically identified, e.g. “Recommendation ITU-R M.541-8”; 3 if the intended reference material is, as a whole, unsuitable as treaty-status text, the reference shall be limited to just those portions of the material in question which are of a suitable nature, e.g. “Annex A to Recommendation ITU-R Z.123-4”. Non-mandatory references

* Note by the Secretariat: This Resolution was revised by WRC-15.

CCPII-2019-33-4357_i 29.05.19 131 4 Non-mandatory references or ambiguous references that are determined to be of a non-mandatory character (i.e. not incorporated by reference) shall use appropriate language, such as “should” or “may”. This appropriate language may refer to “the most recent version” of a Recommendation. Any appropriate language may be changed at any future WRC.

. ANNEX 32 TO RESOLUTION 27 (REV.WRC-1219)

Procedures applicable by WRC for approving the incorporation by reference of ITU-R Recommendations or parts thereof

The referenced texts shall be made available to delegations in sufficient time for all administrations to consult them in the ITU languages. A single copy of the texts shall be made available to each administration as a conference document. During the course of each WRC, a list of the texts ITU-R Recommendation incorporated by reference, and a cross-reference list of the regulatory provisions, including footnotes and Resolutions, incorporating such ITU-R Recommendations by reference, shall be developed and maintained by the committees. These lists shall be published as a conference document in line with developments during the conference. Following the end of each WRC, the Bureau and General Secretariat will update the volume of the Radio Regulations which serves as the repository of texts ITU-R Recommendations incorporated by reference in line with developments at the conference as recorded in the above-mentioned document.

Agenda item 7: to consider possible changes, and other options, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference: “Advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07) to facilitate rational, efficient, and economical use of radio frequencies and any associated orbits, including the geostationary-satellite orbit;

Issue F – Measures to facilitate entering new assignments into the RR Appendix 30B List

BACKGROUND

Article 44 of the ITU Constitution stipulates that for countries to have equitable access to spectrum/orbit resources, administrations shall limit their use to the minimum required to provide services in a satisfactory manner and to endeavour to apply the latest technical advances.

An administration which wants to convert its national allotment of RR Appendix 30B into assignments in an economically viable manner very often needs to modify the initial characteristics of its national allotments, taking into account the latest available development and advancement in technology. For this purpose, the administration will make a submission and follow the procedures of Article 6 of RR Appendix 30B.

In so doing: a) when the submission is examined and published by the Bureau, the submission would need to coordinate with affected networks with higher priority; b) due to the conservative criteria used in RR Appendix 30B, a large number of coordination requirements will be identified; c) networks can be designed with combinations of characteristics, possibly unrealistic, to obtain a high sensitivity to interference from later submissions of other administrations.

As a result, it may be difficult for an administration to successfully complete the coordination within the regulatory period.

Methods to satisfy Issue F

Method F1. To facilitate coordination of submissions of new networks and ease access of administrations to the frequency bands of RR Appendix 30B, a possible method has been identified to update the coordination triggers to take into account technological advances and avoid some unnecessary coordination while assuring adequate protection of other satellite networks. The proposed changes include:  Bringing the size of the coordination arc in line with that used for the unplanned frequency bands, i.e. 7° for C-band and 6° for Ku-band and consequently align the Annex 3 limits to newly established coordination arcs.   Introducing pfd masks and levels like in RR Appendices 30 and 30A as well as in portions of the unplanned frequency bands to remove unnecessary coordination and prevent combinations of technical parameters leading to unrealistic links from hindering introduction of new networks. Proposed values for pfd masks and levels are those developed in preparation for WRC-15, based

CCPI-33-4357-9-1-7/19 29.05.19 138 on a level of protection corresponding to ΔT/T = 6% for C-band antennas with a diameter between 1.2 and 18 m and Ku-band antennas with a diameter between 45 cm and 11 m).

Method F2 This method would be the same as Method F1 except that to allow new submissions of administrations to benefit from already agreed single entry C/I values, the provisions as contained in the current RR Appendix 30B to this effect would be retained.

Method F3 This method would be based on either Methods F1 or F2, but in addition, protection of the existing and operational additional systems recorded in the List prior to a specified date will be provided by applying criteria specified in Annex 4 (Rev.WRC-07) of Appendix 30B to the Radio Regulations.

Method F4. This method proposes no changes to the Radio Regulations. The principle of the RR Appendix 30B is to provide equitable access to the frequency bands. It is important to ensure protection of the assignments in the List and allotments in the Plan of RR Appendix 30B. However, facilitation to enter new assignments into the RR Appendix 30B List through revising the current protection criteria may reduce the protection of assignments in the List and allotments in the Plan of RR Appendix 30B.

ITU-R 64 (RA-15)).

BACKGROUND

Resolution 958 (WRC-15) identifies topics requiring urgent study for inclusion in the Report of the ITU Radiocommunication Bureau Director for WRC-19. In the Annex to this resolution, Section 2 raises the issue of unauthorized operation of uplink terminals. a) whether there is a need for possible additional measures in order to limit uplink transmissions of terminals to those authorized terminals in accordance with No. 18.1; and b) the possible methods that will assist administrations in managing the unauthorized operation of earth station terminals deployed within its territory, as a tool to guide their national spectrum management program, in accordance with Resolution ITU-R 64 (RA-15).

Furthermore, subparagraph 18.1 of Article 18 of the Radio Regulations (RR) establishes that no transmitting station may be established or operated by a private person or by any enterprise without a license issued in an appropriate form and in conformity with the provisions of these Regulations by or on behalf of the government of the country to which the station in question is subject.

Although it is true that both the authorization for earth transmission stations and their operating conditions and the relevant actions to manage earth stations operating without any authorization are the subject of national regulations in every country without detriment to the provisions of the Radio Regulations (RR) and applicable regional agreements, regarding WRC-19 Agenda Item 9.1, Issue 9.1.7, subparagraph 2 a), the Delegation of Mexico supports option 1, which consists of not changing the RR. It also proposes modifying the Annex to Resolution 958 (WRC-15), in order to eliminate subparagraph 2 a). As for subparagraph 2 b) of the same Annex, which focuses on gathering information that will assist administrations in managing the unauthorized operation of the earth station terminals deployed within their territories, the Delegation of Mexico supports all those guidelines that ITU-R deems necessary on the development of capabilities to manage and monitor the radio spectrum in order to identify and geographically locate unauthorized emissions from earth transmission stations.

On the basis of the above, the following Preliminary Proposal for Agenda Item 9.1, Issue 9.1.7 for WRC- 19 is described, as indicated below:

CCPII-2019-33-4357_i 29.05.19 145 To assist administrations in managing (that is, detecting and geographically locating) the unauthorized operation of the earth station terminals deployed within their territories, the ITU-R needs to provide the necessary guidelines in terms of capabilities for technical testing of satellites, along with the possible review and subsequent development of ITU-R reports or manuals on that subject. The latter can provide orientation to administrations and assist them in managing the unauthorized operation of the earth station terminals deployed with their territories, as a tool to guide their national spectrum management programs.

Reasons: Although the authorization for earth transmission stations pertains to each administration and Article 18 of the RR adequately addresses the regulatory measures required internationally, it is useful, in some cases more than in others, for administrations to benefit from information that would assist them in managing the unauthorized operation of the earth station terminals deployed within their territories.

Agenda Item 9.1, Issue 9.1.9: Studies relating to spectrum needs and possible allocation of the frequency band 51.4-52.4 GHz to the fixed-satellite service (Earth-to-space)

BACKGROUND:

Resolution 162 (WRC-15) resolves to invite ITU-R to conduct studies considering additional spectrum needs for development of the fixed-satellite service (FSS) and conduct sharing and compatibility studies with existing services to determine the suitability of new primary allocations to the FSS in the frequency band 51.4-52.4 GHz (Earth-to-space) limited to FSS gateway links for geostationary orbit use, and the possible associated regulatory actions.

ITU-R has conducted studies required by Resolution 162 (WRC-15). The results of analysis of additional spectrum needs are contained in DN Report ITU-R S.[SPECTRUM_NEEDS]. The results of sharing and compatibility studies with incumbent services including the fixed service (FS), mobile service (MS), Earth exploration-satellite service (EESS) (passive), radio astronomy service (RAS), and sharing with potential IMT-2020 applications are contained in PDN Report ITU-R S.[SPECTRUM_SHARING].

Based on the results of studies, no change is proposed to Article 5 of the Radio Regulations unless adequate protection to the passive services operating in the frequency band 52.6 – 54.25GHz can be protected.

BACKGROUND:

The Agenda Item 10 is a standing item on every World Radiocommunication Conference (WRC) agenda and its purpose is to recommend items to the Council for inclusion in the next WRC, as well as possible agenda items for future WRCs.

The agenda for the 2023 World Radiocommunication Conference (WRC-23) will be based on the preliminary agenda items contained in the Resolution 810 (WRC-19), resolves 2, which request appropriate actions in respect of GMDSS, EESS, Space Weather Sensors, FSS, and MS/BS in conformity of the issues 2.1, 2.2, 2.3, 2.4 and 2.5 of this resolution. Additionally other WRC-23 agenda items will be proposed by the ITU Administrations during this study cycle to the WRC-19 discussions and decisions.

Also, in order to orientate the Administrations for the WRC works, the principles which give guidance to the development of the WRC agenda items are exposed at Annex 1 of Resolution 804 (Rev. WRC-12).

In conformity of the past WRCs actions, normally the resolution containing the preliminary agenda for the following conference, i.e. Resolution 810 (WRC-19), will be suppressed and the WRC-19 will approve a new resolution containing the agenda for WRC-23 for consideration by the Council.

PROPOSAL

In order to start the works of SWG-4 (General regulatory, future work & other) and to facilitate the development of future agenda items for WRC-23, Brazil proposes for consideration by the WRC Working Group of PCC-II as follow: 1. to suppress Resolution 810 (WRC-19), Attachment 1 to this proposal; 2. to develop a new Resolution [WRC-23 AGENDA], Attachment 2 to this proposal.

Proceeding as CCP.II work methods at the last WRC, the new Resolution [WRC-23 AGENDA] is proposed to be carried forward as a working document of SWG-4, whereby administrations may add specific agenda item contributions and/or indicate their support for preliminary proposals.

Additionally for reference, Resolution 804 (Rev.WRC-12) which contains the “Principles for establishing agendas for world radiocommunication conferences” is in Attachment 3 to this proposal.

Principles for establishing agendas for world radiocommunication conferences

The World Radiocommunication Conference (Geneva, 2012), considering a) that, in accordance with No. 118 of the ITU Convention, the general scope of the agendas for world radiocommunication conferences (WRCs) should be established four to six years in advance; b) Article 13 of the ITU Constitution relating to the competence and scheduling of WRCs and Article 7 of the Convention relating to their agendas; c) that No. 92 of the Constitution and Nos. 488 and 489 of the Convention require conferences to be fiscally responsible; d) that in Resolution 71 (Rev. Marrakesh, 2002), concerning the strategic plan of the Union, the Plenipotentiary Conference noted the increasingly complex and lengthy agendas for world radiocommunication conferences; e) that Resolution 80 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference and Resolution 72 (Rev.WRC-07) recognize the positive contribution of regional and informal groups and the need for improved efficiency and fiscal prudence; f) the relevant Resolutions of previous WRCs, noting a) that the number of issues addressed in agendas for WRCs has been growing, and that some issues could not be resolved adequately in the time allotted to the Conference, including conference preparations; b) that some agenda items may have a greater impact on the future of radiocommunications than others; c) that the human and financial resources of ITU are limited; d) that there is a need to limit the agenda of conferences, taking account of the needs of developing countries, in a manner that allows the major issues to be dealt with equitably and efficiently; e) that, in accordance with No. 90 of the Constitution, the interval between WRCs should normally be three to four years, to ensure that changes in technology and requirements of Member States are adequately reflected in conference agendas, resolves that the principles in Annex 1 should be used when developing future WRC agendas, resolves to invite administrations 1 to use the template in Annex 2 in proposing agenda items for WRCs; 2 to participate in regional activities for the preparation of future WRC agendas.

CCPII-2019-33-4357_i 29.05.19 158 ANNEX 1 TO RESOLUTION 804 (Rev.WRC-12) Principles for establishing agendas for WRCs A conference agenda shall include: 1) items assigned to it by the ITU Plenipotentiary Conference; 2) items on which the Director of the Radiocommunication Bureau has been requested to report; 3) items concerning instructions to the Radio Regulations Board and the Radiocommunication Bureau regarding their activities, and concerning the review of those activities.

In general, a conference may include on a future conference agenda an item proposed by a group of administrations or an administration, if all the following conditions are met: 1) it addresses issues of a worldwide or regional character; 2) it is expected that changes in the Radio Regulations, including WRC Resolutions and Recommendations, may be necessary; 3) it is expected that required studies can be completed (e.g. that appropriate ITU-R Recommendations will be approved) prior to that conference; 4) resources associated with the subject are kept within a range which is manageable for Member States and Sector Members, the Radiocommunication Bureau and ITU-R Study Groups, Conference Preparatory Meeting (CPM) and the Special Committee.

To the extent possible, agenda items arising from previous conferences, normally reflected in Resolutions, and which have been considered by two successive conferences, should not be considered, unless justified.

In addition, there may be issues that could be addressed through actions undertaken by a Radiocommunication Assembly, particularly those not involving amendments to the Radio Regulations. In developing the conference agenda, efforts should be made to: a) encourage regional and interregional coordination on the subjects to be considered in the preparatory process for the WRC, in accordance with Resolution 72 (Rev.WRC-07) and Resolution 80 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, with a view to addressing potentially difficult issues well before a WRC; b) include, to the extent possible, agenda items that are prepared within regional groups, taking into account the equal right of individual administrations to submit proposals for agenda items; c) ensure that proposals are submitted with an indication of priority; d) include in proposals an assessment of their financial and other resource implications (with the assistance of the Radiocommunication Bureau) to ensure that they are within the agreed budgetary limits for ITU-R; e) ensure that the objectives and scope of proposed agenda items are complete and unambiguous; f) take into account the status of the ITU-R studies related to the potential agenda items before considering them as possible candidates for future agendas; g) distinguish between items intended to result in changes to the Radio Regulations and those dealing solely with the progress of studies; h) arrange items on the agenda by subject to the extent possible.

This document contains an attachment including a Brazilian Preliminary Proposal on WRC-19 Agenda Item 10 for consideration in CITEL’s preparation to WRC-19 Agenda Item 10the upcoming WRC-19.

Agenda Item 10: to recommend to the Council, items for inclusion in the agenda for the next WRC, and to give its views on the preliminary agenda for the subsequent conference and on possible agenda items for future conferences, in accordance with Article 7 of the Convention;

A. BAND 17.3-17.7 GHz

Background:

Demand for Fixed Satellite Service (FSS) in Ka band for GSO broadband applications is ever increasing, with the arrival of High and Very High Throughput Satellites (HTS and VHTS). These systems, based on more efficient use of spectrum thanks to frequency reuse among other techniques, are providing connectivity in remote areas and contributinge to close the digital divide.

The 17.3-17.7 GHz band is allocated in Region 2 on a primary basis to the Broadcasting Satellite Service (BSS) in the space-to-Earth direction, and to the Fixed Satellite Service (FSS) in the Earth-to-space direction limited to feeder links for the broadcasting-satellite service, subject to the application of Appendix 30A procedures (fFootnote 5.5.16 applies). The band is also allocated on a secondary basis to the Radiolocation Service. (Notes 5.514 and 5.515 also apply).

Although in Region 2 the frequency band in the space-to-Earth direction is only allocated to Broadcasting Satellite Service, other Regions already consider the Fixed Satellite Service in this sense direction of transmission. It is further relevant to no note that all primary services in the band, globally considered, are designed for satellite applications (BSS or FSS in different senses of transmission).

The consideration of this band in the space-to-Earth direction for FSS in addition to BSS in Region 2, would meet this increasing demand for connectivity in Ka band for broadband applications, which may not be available under a BSS allocation. This would also provide more flexibility in the design of new satellite systems and a more efficient use of spectrum.

Primary allocation to the fixed satellite service in the space-to-Earth direction in the 17.3-17.7 GHz band in Region 2

The World Radiocommunication Conference (Sharm el Sheik, 2019),

considering a) the need to encourage the development and implementation of new technologies in the fixed- satellite service (FSS) for broadband applications; b) that FSS systems based on the use of new technologies associated with geostationary (GSO) satellite sytem is capable of providing high-capacity and low-cost means of broadband communication even to the most isolated regions of the world; c) that the Radio Regulations should enable the introduction of new applications of radiocommunication technology to ensure the operation of as many systems as possible in order to ensure efficient use of the spectrum;

recognizing a) the need to preserve and protect frequencies subject to the application of Appendix 30A;

noting a) that technology has been developed to provide more efficient use of the spectrum;

CCPII-2019-33-4357_i 29.05.19 163 b) that the frequency band 17.3-17.7 GHz is allocated in Region 2 on a primary basis to the Broadcasting Satellite Service (space-to-Earth) and Fixed Satellite Service (Earth-to-space), subject to the application of footnote 5.516; c) that sharing of Fixed Satellite Service (Earth-to-space) and Fixed Satellite Service (space-to- Earth), is already considered in Region 1 for the band 17.3-17.7 GHz. d) that there is no other primary service in the 17.3-17.7 GHz band apart from the Fixed Satellite Service and the Broadcasting Satellite Service.

resolves that taking into account the results of ITU-R studies, WRC-23 consider a new primary allocation to the Fixed Satellite Service (space-to-Earth) in the 17.3-17.7 GHz for Region 2 without imposing any additional constraints on existing allocations to the Broadcasting Satellite service (space-to-Earth) and Fixed Satellite Service (Earth-to-space).

AGENDA ITEM 10 (C) “NGSO FSS IN THE 71-76 GHz AND 81-86 GHz BANDS” (Item on the Agenda: 3.1 (SGT-4)) (Document submitted by CITEL Member States)

Agenda Item Rapporteur: Martha SUAREZ– CLM – [email protected]

CCPII-2019-33-4357_i 29.05.19 166 Introduction

This contribution proposes a new agenda item to address the gateway needs of NGSO FSS in the 71-76 GHz and 81-86 GHz bands.

Discussion

WRC-97 adopted 5.523A whereby the use of certain frequency bands by geostationary and non- geostationary fixed satellite service networks is subject to the application of the provisions of No. 9.11A and No. 22.2 does not apply. This WRC action allows non-GSO satellite systems to operate in the bands referred to in 5.523A subject to coordination on a first come first served basis with respect to GSO satellite networks.

WRC-97 also adopted provisional equivalent pfd (epfd) and aggregate epfd limits to be met by NGSO satellite systems operating in certain frequency bands. WRC-2000 adopted definitive epfd limits and expanded the ranges of frequency where they would apply. A NGSO satellite system meeting the epfd limits in the relevant frequency bands is deemed to be compliant with Article 22.2 with respect to any GSO satellite network regardless of priority date.

WRC-19 will review the results of the studies and will consider taking appropriate regulatory actions for non-GSO satellite systems in the 37-51.4 GHz frequency range by adopting aggregate criteria not to be exceeded by non-GSO FSS systems in order to protect GSO FSS and GSO BSS networks against interference.

Extremely-High Frequency (EHF) mm-wave bands such as 71-76 and 81-86 GHz are particularly suitable for use as ultra-high capacity gateway links for large constellation non-GSO FSS systems using broadband service links in lower frequency bands, such as the Ku-band and Ka-band. In addition, the EHF frequency bands are potentially suitable for broadband links for certain applications that are not sensitive to deep propagation fading that occurs in EHF bands. As a result, system trials of EHF mm- wave bands are progressing and technology prototypes are maturing.

However, there are currently no mechanisms in the RR establishing coordination procedures applicable between non-GSO systems, nor methods of ensuring satisfactory co-existence with GSO networks, operating in the frequency bands currently allocated to the FSS in the frequency bands from 71-76 GHz (space-to-Earth) and 81-86 GHz (Earth-to-space). Furthermore, Article 21 does not have power-flux density limits in the 71-76 GHz band to ensure protection of terrestrial services.

Lack of regulatory provisions in the 71/81 GHz bands for use under the FSS co-primary allocations contributes to uncertainty in adopting high mm-wave gateway technology among potential operators of non-GSO satellite systems in these bands. This should be addressed by WRC-23.

Proposal

Canada proposes the highlighted text in Annex 1 for consideration under agenda item 10 and addition on the agenda of WRC-23.

Studies of technical, operational issues and regulatory provisions for non-geostationary fixed- satellite services satellite systems in the frequency bands 71-76 GHz (space-to-Earth) and 81-86 GHz (Earth-to-space) and possible new allocation to the FSS in the 71-76 GHz (Earth-to-space)

The World Radiocommunication Conference (Sharm-el-Sheikh, 2019), considering

a) that there is a need for greater broadband connectivity and telecommunication services; b) that satellite systems are increasingly being used to deliver broadband services and are part of the solutions to enable universal broadband access;

CCPII-2019-33-4357_i 29.05.19 168 c) that next-generation fixed-satellite service technologies are required to deliver multi-terabit speeds to support real-time demanding applications, which can be delivered by large constellation non-GSO FSS systems; d) that technological developments such as advances in spot-beam technologies and frequency reuse are used by the fixed-satellite service in the 12 to 30 GHz range to increase the efficient use of spectrum to achieve the targets in the considering above; e) that the high mm-wave bands are particularly suitable for use as ultra-high capacity gateway links for large constellation non-GSO FSS systems using broadband service links in lower frequency bands already allocated to FSS; f) that the particular characteristics of such ultra-high capacity gateway links for large constellation non-GSO FSS systems involve highly directional antennas on both the satellites and the earth stations and, as such, may be conducive to novel frequency sharing arrangements including, but not limited to, consideration of reverse band operation in certain situations; g) that FSS technologies are being developed to support broadband applications in the mm-waves; h) the need to support the development and implementation of new technologies in the fixed-satellite service (FSS) at mm-wave; i) that FSS systems based on the use of new technologies in the EHF mm-wave bands and associated with both geostationary (GSO) and non-geostationary (non-GSO) satellite constellations are capable of providing high-capacity and low-cost means of communication even to the most isolated regions of the world; j) that system trials of high mm-wave bands are progressing; k) that GSO networks and non-GSO systems are at early conceptual phases, thus providing an opportunity to investigate equitable sharing conditions; l) that the Radio Regulations should enable the introduction of new applications of radiocommunication technology to ensure the operation of as many systems as possible in order to ensure efficient use of the spectrum; m) that, unacceptable interference as per No. 22.2 is subject to interpretation and the performance and interference criteria of GSO and non-GSO links have not been established in these bands; n) that technical studies are required in order to ascertain the feasibility of, and conditions for, non- GSO FSS satellite systems sharing the frequency bands 71-76 GHz (space-to-Earth) and 81- 86 GHz (Earth-to-space) for gateway links, with GSO links and with other non-GSO FSS satellite systems; o) that due to early development phase of GSO and non-GSO systems the above studies can be conducted to establish mutually equitable regulations for both types of systems; p) that there are already many stations deployed in some countries in terrestrial services; q) that fixed-satellite applications in spectrum above 60 GHz, such as gateway links with a restricted number of Earth stations, should be easier to share with terrestrial radiocommunication services than high-density fixed-satellite service (HDFSS) applications,

ATTACHMENT

AGENDA ITEM 10: to recommend to the Council items for inclusion in the agenda for the next WRC, and to give its views on the preliminary agenda for the subsequent conference and on possible agenda items for future conferences, in accordance with Article 7 of the Convention;

BACKGROUND INFORMATION:

WRC-15 decided to include on the preliminary agenda for WRC-23 a future conference agenda item to study the additional spectrum needs, sharing and compatibility with existing services, including adjacent services, and the suitability of new primary allocations to the FSS in the frequency band 37.5-39.5 GHz (Earth-to-space) for GSO and non-GSO use. Given the extensive use of this frequency band by fixed service stations globally, the consideration of this band under WRC-19 Agenda Item 1.13 for IMT, and the need to ensure passive service protection in the 36-37 GHz band, it is no longer appropriate to consider the band 37.5-39.5 GHz for this type of “reverse band” operation for FSS.

INTRODUCTION:

A new Agenda item 10 is proposed for WRC-23 to study and develop the technical and regulatory conditions for non-geostationary systems in the fixed-satellite service operating with an orbit whose apogee is equal to or less than 20,000 km, coexisting with geostationary systems in the Fixed Satellite Service and with Stations of the Fixed Service, the Mobile Service, the Earth Exploration Satellite Service (passive) and the Space Research Service (passive) in Region 2 in the frequency band 18.6-18.8 GHz.

Agenda Item 10: To recommend to the ITU Council items for inclusion in the agenda for the WRC of 2023, in accordance with Article 7 of the Convention.

BACKGROUND:

The studies carried out under Agenda Item 1.17 of WRC-2000 that led to the adoption of RR Footnote No. 5.522B were not framed to review all types of non-geostationary systems of the fixed satellite service that could operate in the frequency band 18.6-18.8 GHz. These studies were limited to systems in the fixed-satellite service in high elliptical orbit and low earth orbit. In addition, at that time, a single non-geostationary satellite system was scheduled to operate in that frequency band with an orbit whose apogee was greater than 20,000 km. Today, given the increased global demand for broadband services by low earth orbit and medium earth orbit systems and the progress seen in space-related technologies in recent years, it is deemed necessary to revisit the studies carried out almost 20 years ago in the frequency band 18.6-18.8 GHz, so as to contemplate orbits with apogees equal to or less than 20,000 km. The evidently growing demand for services using the frequency bands 27.5-30 GHz (Earth-space) and 17.7-20.2 GHz (space-Earth) for non- geostationary systems is illustrated by such examples such as the medium Earth orbit O3b constellation, which successfully operates worldwide in parts of these bands, as well as other systems recently launched or in the process of being operational in the near future. Consequently, it is appropriate to facilitate accessing by non-geostationary low Earth orbit and medium Earth orbit systems to spectrum in the space-to-Earth direction in the band 18.6-18.8 GHz, thereby enabling their contiguous use in the range 17.7-20.2 GHz, for which it is essential to consider coexistence with other services that could potentially be affected.

OBJECTIVE:

We propose studying and developing the technical and regulatory conditions under which non- geostationary satellites with an orbit whose apogee is equal to or less than 20,000 km can operate without causing unacceptable interferences to the stations of other services having primary attributions in the frequency band 18.6-18.8 GHZ.

Study of the technical and regulatory provisions for non-geostationary systems in the fixed-satellite service operating in the frequency band 18.6-18.8 GHz with an orbit whose apogee is less than 20,000 km

The World Radiocommunication Conference (Sharm-El-Sheikh, 2019), considering a) that in Region 2, the frequency band 18.3-19.3 GHz is one of those identified in Footnote No. 5.516B of the Radio Regulations for use by high density applications of the Fixed Satellite Service in the space-Earth direction; b) that several non-geostationary satellite systems of the Fixed Satellite Service are deployed with orbits whose apogees are less than 20,000 km and operate in bands adjacent to the frequency segment 18.6- 18.8 GHz; c) that, in accordance with Article 22, non-geostationary systems shall not cause unacceptable interference to the geostationary satellite networks of the Fixed Satellite Service and the Broadcasting Satellite Service, operating in accordance with the provisions of the RR and, unless otherwise stated in the Regulations, they should not claim protection against them; d) that the 18.6-18.8 GHz band is also allocated on a primary basis to the Earth Exploration Satellite Service (passive) and the Space Research Service (passive), given that Article 21, Table 21-4 establishes a maximum power flux-density limit for systems in the fixed-satellite service in order to make coexistence viable. The studies that showed the need to establish the above limit were based on a non-geostationary system of the fixed satellite service with an orbit whose apogee was greater than 20,000 km; observing that, at present, there are numerous geostationary satellite networks in the fixed-satellite service operating in the frequency band 18.6-18.8 GHz in accordance with the provisions of the RR, recognizing a) that the frequency band 18.6-18.8 GHz is allocated worldwide to Fixed, Mobile, Fixed by Satellite (space-to-Earth), Earth-Satellite Exploration (passive) and, in Region 2, to the Space Research Service (passive);

CCPII-2019-33-4357_i 29.05.19 177

b) that the emissions of the Fixed Service and the Fixed Satellite Service in the band 18.6-18.8 GHz are limited to the figures given in No. 21.5A and 21.16.2, respectively, pursuant to Footnote No. 5.522A; c) that emissions from the Mobile Service in the band 18.6-18.8 GHz are limited to the figures given in No. 21.5; d) that the limits referred to in paragraphs b) and c) above apply to the Fixed Service, the Mobile Service and the Fixed Satellite Service stations operating at an apogee of 20,000 km, which should remain unchanged to protect the current and future Earth Exploration Satellite Service (passive) and the Space Research Service (passive) in the frequency band 18.6-18.8 GHz; e) that in the frequency band 18.6-18.8 GHz, the networks of the geostationary and non-geostationary systems of the Fixed Satellite Service operate in accordance with the provisions of No. 5.522B; f) that No. 21.16 establishes the power flux density limits applicable to the Fixed-Satellite Service systems to protect the Fixed and Mobile Services allocated in the frequency band 18.6-18.8 GHz; h) that No. 21.17 does not apply to the frequency band 18.6-18.8 GHz, resolves to invite the ITU-R 1. to conduct compatibility studies between non-geostationary systems of the Fixed Satellite Service (space-to-Earth) operating with an apogee of less than or equal to 20,000 km and the Earth Exploration Satellite Services (passive) and Space Research Services (passive) in the frequency band 18.6-18.8 GHz; 2. to study the possibility of applying the equivalent power flux-density (epfd) limits specified in Table 22-1B to the frequency segment 18.6-18.8 GHz to ensure that non-geostationary systems in the fixed- satellite service (space-to-Earth) do not cause unacceptable interference to networks of geostationary systems in the fixed-satellite service when operating in the frequency band 18.6-18.8 GHz; 3. to develop technical and regulatory provisions for non-geostationary stations operating in the Fixed Satellite Service (space-to-Earth) with an apogee less than or equal to 20,000 km in the frequency band 18.6-18.8 GHz, while ensuring the power flux-density limits of Article 21, Table 21-4, intended to protect the Fixed Service and Mobile Service in that frequency band; resolves further 1. that compliance with the equivalent power flux-density limits in Table 22-1B should ensure protection of geostationary system networks in the fixed-satellite service operating in the frequency band 18.6- 18.8 GHz from any unacceptable interference; 2. that the technical and regulatory provisions to be developed must guarantee that, in the band 18.6-18.8 GHz, there will be no change to the limits referred to in No. 21.5, 21.5A and 21.16.2, applicable to the Fixed Service and the Mobile Service, and to the stations of the geostationary and non-geostationary satellite systems operating in the Fixed Satellite Service with an orbit whose apogee is greater than 20,000 km, invites the 2023 World Radiocommunication Conference to consider the findings of the proposed studies and to take the pertinent actions, invites the administrations to participate actively in the studies and to help provide the technical and operational features of the systems involved by submitting their contributions to the ITU-R.
