Hi Yanjun,

I agree that the PS160 subfield is set to 1 for 320 MHz indication. My point is that the way of processing the PS160 subfield for 320 MHz indication by an EHT non-AP STA should be similar to the way of processing B0 of the RU Allocation subfield for 160/80+80 MHz indication by a HE non-AP STA. According to the current text, a HE non-AP STA ignores B0 of the RU Allocation subfield for 160/80+80 MHz indication. Similarly, an EHT non-AP STA can ignore the PS160 subfield for 320 MHz indication.

Best regards,

Lei

Hi Lei,

Thank you for the prompt review and fixing the typo!

It’s a good question on whether to require the PS160 subfield set to 1 when decoding the 320 MHz RU. It looks better to keep the current PDT text (i.e., require PS160=1) from the following 3 aspects and please let me know if you have additional concerns/suggestions:

The existing EHT RU table in D1.0 (snapshot below) requires the PS160 subfield set to 1 when decoding the 320 MHz RU, so the current PDT is more aligned with D1.0.
The current PDT avoids multiple ways of indicating the 320 MHz RU, which simplifies and avoids ambiguity in transmitter/receiver design.
By requiring the PS160 subfield set to 1, the 2^nd row in the existing EHT RU table below can be saved as a reserved combination for future use as in D1.0.

Thanks,

Yanjun

Hi Lei and all,

Thank you for the constructive inputs and I’ve adopted most of them.

All the changes are tagged with “R1” in the attached based on Lei’s suggestions and offline inputs: added description on the PS160 subfield; added text to disallow MU-RTS in an EHT MU PPDU; revised text and illustration.

Please let me know if you have any additional comments/suggestions. I’m going to upload this as r1 if no further input is received by tomorrow’s meeting.

Thanks,

Yanjun

Hi Alfred,

Could you help add the document 21/0991r0 on MU-RTS to the queue for joint calls?

I’ll upload the document once it’s ready.

Thanks,

Yanjun
