Re: [STDS-802-11-TGBE] [STDS-802-11-TGBE] Request feedback for TBD/CR in the Restricted TWT setup subclause

Boyce, Frank,

Thanks for sharing your comments. Please see the attached document with some responses.

There have been some questions/comments on the traffic requirement etc. and questions on TIDs' role here.
We agree that STA may want to share the traffic characteristics and requirements with AP or even wants to change default packet classification (mapping) to TID. Those can be done using existing or extended tool(s) (TSPEC e.g.). I believe Duncan etc. have a contribution on TSPEC variant/lite, and Dibakar etc. have a contribution on SCS change.
In this set up procedure, we focus on the general rTWT set up procedure, and that it operates at TID level inline with that the blockack agreement is established at TID level.
Please note that there is a subclause 35.7.2.2 traffic classification/requirements are discussed.

Thanks.
Chunyu

Hi, Jarkko:

Since restricted TWT is intended to service latency sensitive traffic, we need a mechanism to provide the identification for such traffic streams. TID is the right level rTWT operates at to avoid problem such as head-of-fifo blocking.
So in both DL and UL, the traffic transmitted during rTWT SPs is constrained to the TID(s) that AP/STA agreed on during the rTWT setup.

Thanks.

Hi Chunyu,
the R-TWT proposal has DL TID and UL TID bitmaps. 
I am wondering how these are used? 

- In DL why would AP limit the TIDs it is allowed to transmits to the STA? 
- In UL can STA transmit from other TIDs than signaled here? 

Cheers,
Jarkko
