Abstract This document contains the minutes from the PHY conference call on Apr. 1, 2010

Notice: This document has been prepared to assist IEEE 802.22. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein.

Release: The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE 802.22.

Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures , including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE 802.22 Working Group. If you have questions, contact the IEEE Patent Committee Administrator at .

4 Notes

 The meeting started at 9:10 pm and ended at 11: 00 pm ET  All attendees were aware of the IEEE patent policy  The agenda was approved.

8.9 Control Mechanisms (V2.1) Zander briefed that the agreement in Orlando meeting was to re-write the sub-clauses 8.10.1 and 8.10.1.1 of V2.0 (i.e 8.9.1 and 8.9.1.1 of version 2.1) phrase. This was assigned to Jason and he had uploaded the suggested change in DCN 58.

During the call, the text change was approved in principle with further refinement. Specifically, - Session 8.9 structure: o 8.9 Control Mechanisms o 8.9.1 Downstream synchronization o 8.9.2 Upstream synchronization o 8.9.3 Opportunistic upstream burst o 8.9.4 Power Control - In 8.9.1 o “The DS synchronization process should be performed using the superframe preamble” -> “Superframe and frame preambles may be used to perform the DS synchronization” o “minimum time” -> “sufficient time” - In 8.9.2 o “… shall maintain …” -> “… shall ensure …” - Subclause title “8.9.2.1.2 initial ranging” -> “8.9.3.1.2 initial ranging transmission”

In addition, Sung Hyun pointed out that the two paragraphs right after Table 248 in page 373 (version 2.1) have yet to be updated according to DCN36 rev3 as in the resolution to comments #378/#933 . Gerald would make the change in the new draft V3.0

8.6 Subcarrier Allocation Zander summarized that the group agreed after long discussions in Orlando meeting to rewrite 8.6 sections, including 8.6.1 through 8.6.5. The sessions 8.6.2 through 8.6.5 will be based largely from DCN 220rev1 that was contributed by Isabelle/John of France Telecom and reviewed/amended by Zander/Gerald. The work was assigned to Jason in Orlando meeting and the text change for the whole subclause 8.6 was captured in DCN220rev2.

Jason went through the whole document and explained the changes suggested. The document was agreed in principle with further amendment below: - Table 1 in 8.6.3 and Table 4 in 8.6.4 in the document will be updated according to the parameter set “32, 2, 3” for block size 1440. - Rephrase 2nd paragraph in 8.6.5 above Table 5 for clarification. (parameter q has been set to 2 for all block sizes)

Jason will update by early next week so that Gerald could update the version 3.0 for Letter Ballot in time.
