Re: [STDS-802-11-TGBN] Co-BF/Co-SR Trigger frame format discussion

Hi Jason,

Reply to your responses to my comments:
1. Prefer to use "MU PPDU" instead of "PPDU" for two reasons. Firstly, CoBF and CoSR use MU PPDU. Secondly, the U-SIG field structure (and the fields mentioned in U-SIG) and the existence of UHR-SIG or EHT-SIG relies on the PPDU being an MU PPDU. Understand that there are too many instances of "PPDU". If time allows, you can address this, otherwise leave to future CR.

2. I remembered wrong. You're right. MCS is not in the CoBF Invite frame. And it should not be in the Invite frame.

Regards,
Alice

Hi Jason,

 

Attached please see my comments. The baseline 11-26/23r1 document was downloaded from server, not the one from your first email.

 

Could you please add me as a contributor and keep me in the loop? Also add me to the Co-BF and Co-SR Invite and Response frame documents and discussion threads.

 

Regards,

Alice
