Re: [STDS-802-11-TGBE] [EXT] [STDS-802-11-TGBE] 答复: [STDS-802-11-TGBE] 22/552r2 Individual TWT

With the Target TWT Wake Time referring to the TSF time of the link where the TWT Setup frame is transmitted, the frame content of frame needs to be changed if the retransmission of the frame is in a different link. Is it possible to refer the start time to a fixed link?

 

Best Regards,

Liwen

Hi Ming,

 

If I understand correctly, what you want is to derive the TWT times of the other links from the TWT time indicated in the TWT element transmitted on one of the links so that the TWT start times across multiple links are aligned. Maybe better to spell that out as follows?

 

"• If multiple links are indicated in the Link ID Bitmap subfield of the TWT element, then multiple TWT agreements are requested to be setup; A TWT agreement is requested on behalf of each of the STAs affiliated with the same MLD and that is operating on each of the indicated links.

• The same TWT parameters are requested for all the links.
• The target wake time (TWT_r) of the Target Wake Time field of the TWT element shall be in reference to the TSF time (TSF_r) of the link the TWT element is sent.
• The target wake time of i-th link indicated in the Link ID Bitmap subfield (TWT_i) is derived from the Target Wake Time field of the TWT element as follows: TWT_i = TWT_r + TSF_offset, where TSF_offset = (TSF_i - TSF_r) and TSF_i is the TSF time of the i-th link.
(CID#6240 6241)"

Regards,

Minyoung
