[STDS-802-11-TGBN] TGbn PHY Motions Request

Hi Alfred,

 

Please add the following SPs (all passed without objections in doc 11-24/1822r3) to the TGbn motions list:

 

  1. Move to add the following to the SFD:
    • The pre-UHR portion (the portion up-to and including UHR-SIG) of the COBF PPDU shall be transmitted in a non-beamformed (omni) manner.
  2. Move to add the following to the SFD:
    • The pre-UHR portion of a COBF PPDU shall have identical content across two APs.
  3. Move to add the following to the SFD:
    • COBF data transmission shall be indicated in the U-SIG for 802.11bn.
  4. Move to add the following to the SFD:
    • In a COBF transmission, the maximum number of spatial streams given to one user will be 2.

 

Thanks,

Sameer

Hi Alfred,

 

Can you please add the following six PHY motions to the queue (all based on SPs from document 11-24/1542r5) ?

 

Thanks,

Sameer

 

 

 

Motion 1:

 

  • Move to add the following to the SFD:
    • The Coordinated beamforming (COBF) transmission phase in 802.11bn shall be limited to 2 APs

 

Motion 2:

 

  • Move to add the following to the SFD:
    • The sequential NDP based sounding protocol will be as shown below for COBF
      • Sounding happens one BSS at a time
      • NDPA only addresses the in-BSS STAs
      • MAC related additional frames are TBD

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 


Motion 3:

 

  • Move to add the following to the SFD:
    • The joint NDP based sounding protocol will be as shown below for COBF
      • Sounding happens for one BSS’s STAs at a time
      • NDPA only addresses the in-BSS STAs
      • MAC related additional frames are TBD
      • Joint NDP based feedback will be based on large V-based feedback where the eigen-vectors span the antennas across both Aps

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 


Motion 4:

 

  • Move to add the following to the SFD:
    • For joint NDP based sounding, one AP will frequency synchronize to the other for both of its NDP transmissions
      • For both the NDPs, the AP doing the correction brings its frequency within a certain TBD range of the reference AP

 

 

Motion 5:

 

  • Move to add the following to the SFD:
    • For joint NDP based sounding, one AP will frequency synchronize to the other for both of its NDP transmissions
      • For both the NDPs, the AP doing the correction brings its frequency within a certain TBD range of the reference AP

 

Motion 6:

 

  • Move to add the following to the SFD:
    • In the UHR sounding process for COBF, for the joint sounding case as well as for the sequential sounding case, the NDP shall always carry the BSS color of the AP which transmitted the NDPA
