Re: [STDS-802-11-TGBB] Comments on Relayed CCA

Hi Volker,

Thanks for the points. We can talk about point 1 today, when I hope we will get to it.

 

I’ll also add the timeline discussion for the end of the week.

Kind regards,

Nikola

Subject: AW: Comments on Relayed CCA

 

Dear Nikola,

 

I have two further points for the agenda.

 

  1. discussion of my comments against 11-21/0280r1 (10 minuts).
  2. discussion on the ammendment ordering and update doc. 11-18/1290r7 (10 minutes). The decision in the Editors meeting has been postponed until May. The relevant time stamp is the time to go to REVCOM. I suggest to update our timeline so that this time stamp is included, taking the typical duration of WG and SA ballot for a short ammendment into account. Nearest to TGbb would be TGba which has 189 pages currently. The TGba has started  in July 2016, it had D1.0 in Nov. 2017 and their D8.0 is planned to go to REVCOM out of March 2021.

 

Best regards - Volker

Betreff: Comments on Relayed CCA

 

Dear Nikola, Chong,

 

I have some remarks regarding the relayed CCA scheme proposed in doc. 11-21/0280r1. My two main problems are

  1. it ends in a desaster if it is occassionally also used in non-AP STAs.
  2. it needs full-duplex support at APs which increases complexity

My personal view is it should be optional and if used, in no way activated at non-AP STAs.

 

I hope these comments are helpful for you.

 

Best regards - Volker
