Re: [STDS-802-11-TGBE] Discussion on HE or EHT variant differentiation of a trigger frame

Hi Ross, all,

Before we discuss on the call, I’d like to point out two things here:

  1. We agreed A-PPDU is an R2 topic and there was almost no discussion in R1 on the feasibility of supporting mixing HE and EHT STA and how to mixing them. Given that, the hypothesis of R1 STA is transparent to A-PPDU is very unsafe. I highly recommend to not design a protocol based on the presumably “transparency”.
  2. We just passed the SP of using B55 to indicate the presence of “special user field” a week ago and now this contribution is trying to revert the consensus. I don’t see a strong justification to go back and force.

 

BRs,

Xiaogang.

Subject: [STDS-802-11-TGBE] Discussion on HE or EHT variant differentiation of a trigger frame

 

Hi all,

 

I have updated the following contribution to r2 for people’s better understanding. This proposal talks about how a R1 EHT STA differentiates HE or EHT variant, or we can say, how to decide whether to transmit HE TB PPDU or EHT TB PPDU, when receiving a trigger frame. The proposed method 3 enables a R1 EHT STA to transmit either HE TB or EHT TB PPDU depending on a R2 AP’s schedule, with no additional bits needed. Just relies on the existing bits in the trigger frame.

Please review and we can discuss in the next joint call. All comments are welcome.

Hi Alfred,

 

Please add the following contribution to the joint queue, this is related with the trigger frame PDT (11/21-0259r3). Hence I want to discuss this together with the trigger frame PDT. Thanks.
