Re: [STDS-802-11-TGBN] [EXT] Re: [STDS-802-11-TGBN] TGbn PHY Motion Request

Hi Alfred

 

Please add the following to the 11bn PHY motions list:

 

1.

•       Do you support to add the following to the SFD?

–      Both sequential NDP based and joint NDP based sounding options will be supported for COBF in 802.11bn

 

Result: No objection

 

2.

•       Do you support to add the following to the SFD?

–      Two separate capabilities shall be defined for the maximum number of spatial streams supported for reception of a sounding NDP in UHR and the maximum total number of streams (across all users) supported for reception in UHR DL MU-MIMO and CoBF PPDUs

•       The only possible values for each capability are 4 and 8

 

Result: No objection

 

Thanks,

Ron
