[STDS-802-11-TGBF] clarification on TF sounding

["Sahoo, Anirudha (Fed)" <00001823ca88828f-dmarc-request@xxxxxxxxxxxxxxxxx>]

Hi all,

  In the D0.01 draft, in 11.21.18.6.3 TF sounding phase it says:

“The Sensing Sounding Trigger frame shall allocate uplink resources for one or more STA’s R2I NDP transmission covering the full bandwidth.”

 

1. So, these uplink resources are RUs, right?
2. If yes:  if there are multiple STAs involved, then each RU allocated to a STA will be less than the full bandwidth. Then, does the above mean that “all RUs together will add up to full bandwidth”?
3. If R2I NDPs are sent in RUs, and there are quite a few STAs acting as sensing transmitter, then the RUs may have very few subcarriers and the CSI information on those few subcarriers may not be good enough for the application. Is this a problem? Or maybe the AP will not involve so many STAs in the TB polling phase (will do it in multiple TB polling phases)?

 

 

thanks and regards
