Re: [STDS-802-11-TGBE] 答复: [STDS-802-11-TGBE] TGbe Teleconferences [03/22/2021 and 03/24/2021]: Agendas Posted

Hi Ross,

We have the same feeling about the clarity of the SR fields in the 11ax spec. We are looking into this and hopefully in the process of CR of 11be spec, we may also improve the clarity of the 11ax spec. 

Thanks,
Alice

Hi Alice and all,

 

I have got same question as Eunsung. I understand Alice copied from 11ax. Whilst it seems unclear for 11ax spec itself.

Hi Alice,

 

If we consider the case where 20 MHz and 80 MHz operating STAs participate in 80 MHz TB PPDU transmission, 20 MHz operating STA has SR1=SR2 whereas 80 MHz operating STA has SR1=!SR2. Is it correct? If so, it can cause different U-SIG content in the 80 MHz TB PPDU. I’m not sure why we need to set SR1=SR2 for 20 MHz operating STAs in a wider bandwidth transmission.

 

Best regards,

Eunsung

Hi Eunsung,

 

Yes. You are correct. We got the exact wording from the SR fields in HE-SIG-A in HE TB PPDU. And that was the way how it was being set back in 11ax, if we're correct.

 

Best regards,

Alice

Hi Alice,

 

Thanks for preparing the resolutions.

I have a question for clarification. Regarding the resolutions for CID 1618 and 2634, you added the sentences in orange into the Spatial Reuse 2 field as below. Could you clarify what the sentence “If the STA operating channel width is 20 MHz or 40 MHz ~” means? That means a 20 or 40 MHz operating STA sets the Spatial Reuse 2 field to the same value as the Spatial Reuse 1 field?

 

 

Best regards,

Eunsung

Hi Alfred,

 

Please add the comment resolutions on U-SIG part 4 (495r0) to the PHY queue.

 

Thanks,
