[STDS-802-11-TGBE] CID 15103 in document 317



Hi Xiaogang, all,

 

Following up from the discussion, I wanted to clarify that the Rejection reason I mentioned during the call was as follows. Note that CID 14115 was discussed in the previous round and it was rejected after some discussion within the group.

 

14115

Li-Hsiang Sun

35.3.17

464.30

"The STA affiliated with the non-AP MLD that received the initial Control frame does not
respond to the most recently received frame from the AP affiliated with the AP MLD that
requires immediate response after a SIFS"

This should not be applicable to sounding because EMLSR STA may not be the first group of STAs triggered by the first BFRP trigger

For sounding sequence, the end of frame exchange does not occur until the EMLSR receives a BFRP trigger or until intra-BSS NAV expires

22/1848r2

J

REJECTED
The EMLSR switch back rules are quite clear - an AP knows that if it does not schedule all the STAs affiliated with non-AP MLDs in EMLSR mode (that it has triggered via BSRP/MU-RTS and included in the NDP Announcement frame) in the first BFRP Trigger frame, the non-AP MLDs that aren’t included in the first BFRP Trigger frame will switch back to listening operation.

 

If we are to go with a NOTE, the note should reflect what is mentioned in the above rejection reason.

 

Also, to clarify to Rakesh, I was not suggesting that the normative rules be converted a NOTE.  The normative rules were to specify AP behavior. The NOTE is to clarify non-AP behavior if AP does not include the non-AP in the first BFRP trigger frame.

 

Thanks,

Gaurang
