Re: [STDS-802-11-TGBN] Co-BF SPs Request



Hi Sherief,

 

Regarding 942, I have following comments:

  1. Need to ensure that the CBF transmission sequence only happens with non-AP UHR STAs that support CBF procedure and not every UHR non-AP STA associated to a sharing/shared AP.
  2. Need to ensure that the ICF containing extended timeout period is not sent to associated non-AP UHR STAs that support EMLSR/DPS but don’t support CBF procedure or has disabled it.

 

Regards,

Dibakar

Hi Alfred,

 

Would you kindly add the following list of SPs to the queue?

 

  • Do you agree that an AP shall use the BSRP GI3 Trigger frame variant for the Sounding Invite frame
    • The Sounding Response frame shall be M-BA
    • TBD whether there’s another frame variant allowed for the Sounding Invite/Response frame

 

  • Do you agree that an AP shall use the BSRP GI3 Trigger frame variant for the CoBF Invite frame
    • The CoBF Response frame shall be M-BA
    • TBD whether there’s another frame variant allowed for the CoBF Invite/Response frame

 

  • Do you support that if a CoBF sounding sequence within a TxOP includes Cross-BSS and In-BSS sounding, then the Cross-BSS sounding portion shall come first?
    • If In-BSS sounding fails, it can be redone using legacy sounding without any involvement of the other AP.

 

 

Regards,

Sherief
