Hi Alfred,

On behalf of my co-worker Sameer Vermani, we have some SP requests.

1. We would like to rerun the following failed SP. Logically, it may be run before the deferred SP mentioned in You-Wei's previous email, in the TGbn Joint session.

SP1 – Sameer Vermani – CBF

Do you agree to add the following to the 11bn SFD:

· For the COBF case, the information in the NDPA for the responding AP has a unified design for joint-NDP based sounding as well as cross-BSS section of sequential sounding.

Supporting documents: [24/1822r4]

Result: 28Y, 17N, 8A

2. There is a deferred SP from teleconference, to be run in PHY.

SP5 – Shengquan Hu – CBF

Do you agree to include the following text to the 11bn SFD?

· 1-bit indication in the per-user SIG field to resolve the BSS color for COBF transmissions.

o The coding bit is re-purposed for this indication

Supporting doc: [11-24/1829r1, 11-24/1822r4]

Result: Deferred

3. A new PHY SP request.

SP: Do you agree to include the following to the 11bn SFD?

2 BSS colors are indicated in the preamble of a COBF PPDU.
One BSS color for the sharing AP and another BSS color for the shared AP

Supporting doc: [11-24/1822r4]

Regards,

Alice Chen
