TGba Editor: Instruction: change subclause 11.2.3.1 as the following:

11.2.3 Power management in a non-DMG infrastructure network 11.2.3.1 General

(…existing texts…)

A STA operating in PS mode that is neither in WNM sleep mode nor in WUR Mode shall periodically listen for Beacon frames, as determined by the ListenInterval parameter of the MLME-ASSOCIATE.request or MLMEREASSOCIATE.request primitive and the ReceiveDTIMs parameter of the MLME-POWERMGT.request primitive.

(…existing texts…)

TGba Editor: Instruction: Insert subclause 31.5 Power management with WUR as the following:

* Power management with WUR mode

WUR is a service that may be provided by a WUR AP to its associated WUR non-AP STAs.

A WUR non-AP STA can be in WUR Mode or WUR Mode Suspend while using WUR service provided by a WUR AP.

To use the WUR service, a WUR non-AP STA exchanges WUR Mode Setup frame with a WUR AP within the same infrastructure BSS, and the detail is defined in Table 31-xxx (WUR Mode setup frame exchange).

Table 31-xxx - WUR Mode setup frame exchange

Request frame: Action Response frame: Action Response frame: WUR Type field within a WUR Type field within a WUR Mode Response Status Status after the Mode Setup frame Mode Setup frame field within a WUR Mode completion of the transmitted from a WUR transmitted from a WUR Setup frame transmitted exchange non-AP STA to a WUR AP STA to a WUR non- from a WUR AP STA to a AP STA AP STA WUR non-AP STA

After a WUR non-AP STA negotiates WUR service with a WUR AP, the WUR non-AP STA may switch from WUR Mode to WUR Mode Suspend or switch from WUR Mode Suspend to WUR Mode by initiating and completing a successful frame

Submission page 12 Po-Kai Huang, Intel Jan 2018 LB2050 exchange, which includes a WUR Mode Setup frame with Action Type field of the carrying WUR Mode element set to “Enter WUR Mode Suspend” or “Enter WUR Mode” from the WUR non-AP STA and an Ack frame from the WUR AP.

The Action Type field in the WUR Mode element of the WUR Mode setup frame sent by the WUR non-AP STA in this frame exchange indicates the status that the STA shall adopt upon successful completion of the frame exchange.

After a WUR non-AP STA negotiates WUR service with a WUR AP, the WUR non-AP STA may teardown WUR service by initiating and completing a successful frame exchange, which includes a WUR Mode Teardown frame from the WUR non- AP STA and an Ack frame from the WUR AP.

3 1. 5. 1 non-AP STA operation

The WURx of a WUR STA can be in one of two states: — WURx Awake: the WURx of the WUR non-AP STA is fully powered. — WURx Doze: the WURx of the WUR non-AP STA is not able to receive WUR frame.

A WUR non-AP STA enters WUR Mode to enable its PCR to sleep for extended periods and enable its WURx to receive WUR frame from the WUR AP.

If a WUR non-AP STA is in WUR Mode, then:

 the WUR non-AP STA shall be in WURx awake state during the ON Duration of the duty cycle schedule agreed between WUR AP and WUR non-AP STA if the WUR non-AP STA is in the doze state

 T he WUR non-AP ST A ma ybe in WUR doze x s ta te afte r a successf ul f rame e xchange w it hthe WUR AP ,w hich inform the s WUR AP that the WUR non-A PST A is the aw ake s ta te  the WUR non-AP STA may not listen for Beacon frame if the WUR non-AP STA is in PS mode (see 11.2.3.1 (General)

 the WUR non-AP STA may not be in the awake state during the negotiated service period of PCR schedule between the WUR AP and the WUR non-AP STA

 The parameters of the negotiated service period for the WUR non-AP STA’s PCR schedule between the WUR AP and the WUR non-AP STA are maintainedby the WUR non-AP STA

NOTE 1 – The WURx duty cycle schedule agreed between WUR AP and WUR non-AP STA may be that WUR non-AP STA is always in WURx awake state.

NOTE 2 – Examples of the negitated service period between WUR AP and WUR non-AP STA for the WUR non-AP STA’s PCR schedule include TWT and schedule for WNM sleep mode.

A WUR non-AP STA enters WUR Mode Suspend to utilize PCR operation while maintaining negotiated WUR parameters.

If a WUR non-AP STA is in WUR Mode Suspend, then:

 W UR non-AP STA m ay be i n WUR doze x s ta te

 t he negotia te d WUR parame te rs betw een t he W UR A Pa nd t he W UR non-AP STA a re m ai ntai ned by the W UR non-AP ST A

NOTE – If a WUR non-AP STA is in WUR Mode Suspend, the existing negotiated service period between WUR AP and WUR non-AP STA for the WUR non-AP STA’s PCR schedule is active and is not suspended.

3 1. 5. 2 AP STA operation

A WUR AP shall maintain for each associated WUR non-AP STA that requests WUR service a WUR status that indicates whether the WUR STA is in WUR Mode or WUR Mode Suspend.

When a WUR non-AP STA is in WUR Mode, then:

 T he WUR AP ma ys end a wa ke-up f rame to the WUR non-A PST A if the WUR non-AP STA is in the doze state, and the WURx duty cycle schedule agreed between WUR AP and WUR non-AP STA indicates that the WUR non-AP STA is in WURx awake state.

 The parameters of the negotiated service period for the WUR non-AP STA’s PCR schedule between the WUR AP and the WUR non-AP STA are maintained by the WUR AP

When a WUR non-AP STA is in WUR Mode Suspend, then:

 t he negotia te d WUR parame te rs betw een t he W UR A Pa nd t he W UR non-AP STA a re m ai ntai ned by the W UR AP
