Re: [STDS-802-11-TGBN] [EXT] Discussion on CID15027 in 11-26/1765

Hi Yajun,

 

What you mentioned is not what I said. What I said in the meeting is that the TWT, TXOP without NPCA being enabled also define the end time after which the frame exchange can not be performed. The optimization per the end time instead of the transitioning to LC mode rule is not necessary.

 

Best Regards,

Hi, Liwen

 

For CID 15027, I agree with your point mentioned in the last meeting that when a DPS non-AP STA is on the NPCA primary channel, there might be an R-TWT SP, in which case the DPS non-AP STA may not switch back to LC mode even if the NPCA timer has expired.

 

However, in other cases, the DPS non-AP STA should switch back to LC mode when the NPCA_Timer expires. It makes no sense to keep the non-AP STA in HC mode when the NPCA_Timer expires, except wasting energy.

 

Therefore, I suggest modifying the resolution as follows: adding the following sentence in P422L35 of draft 2.1:

“when a DPS non-AP STA switches to the NPCA primary channel and transitions/is triggered to HC mode for transmission, it shall switch back to LC mode upon expiration of the NPCA_Timer, except that the expiration of the NPCA_Timer occurs during an R-TWT SP of which the non-AP STA is a member.”

 

Please let me know your thoughts on this, and I look forward to your reply.

 

BRs，

Yajun
