Re: [STDS-802-11-TGBE] Discussion on 11-21/1224 CC 36 CR for Restricted TWT Setup

Hi Kumail,

 

Thanks so much for sharing the document.

 

For the peer-to-peer part, some clarification would be helpful. Current text seems to be open for interpretation. For instance, when you say once peer-to-peer bit is set to 1, it would mean that AP ‘allows’ the rTWT schedule for peer-to-peer communication. A few cases can happen here—

 

1.      Interpretation 1: The same rTWT schedule is used for both UL/DL communication and  peer-to-peer communication.

-        Now, there is some control for UL/DL communication through TID (latency-sensitive) negotiation using existing spec. But the concern is that there is no such control for peer-to-peer communication. When you mix UL/DL and peer-to-peer for the same schedule, the peer-to-peer STAs can transmit any kind of traffic (latency-tolerant) while the STAs involved in UL/DL transmission are latency-sensitive traffic-only within the same rTWT SP, which is not fair for the latter group of STAs, right?

-        Some other questions—

o   How to do the setup for peer-to-peer? Does only one of the peer-to-peer STAs need to establish rTWT  membership with the associated rTWT scheduling AP or both peer-to-peer STAs need to establish rTWT membership in order to utilize the rTWT schedule for peer-to-peer communication?

2.      Interpretation 2: Separate rTWT schedules are used for UL/DL transmission and for peer-to-peer transmission

-        How to control the TIDs so that only latency sensitive TIDs are allowed for transmission over the peer-to-peer link?

 

If you could clarify overall peer-to-peer operation, that would be great.

 

Best

Rubayet
