Hi Ross and all,

I checked the 11ax cases in the table with Youhan. (Thank you, Youhan)

And it turned out some parts need to be updated.

First of all, puncturing signaling is now decoupled from bandwidth information in 11be (differently from 11ax). Since it is not necessary to consider EHT-CBW-PUNC80/160/320, all related description is removed from the table.
In case of EHT TB PPDU, its transmit bandwidth is still 20/40/80/160 MHz regardless of assigned RUs, delete “except for EHT TB PPDU” in the initial draft.

If there are additional comments, please let me know.

Regards,

Yujin

Hi Yujin,

Thanks for preparing the PDTs.

You have several parts mentioning SST operation is in TBD. I suggest to remove the sentence to reduce the number of TBDs. Later if we define specific operation in 11be, we can add the specific description for SST operation.

è I will remove it from the table.

Also there are serval parts mentioning TBD in EHT TB PPDU for EHT-CBW-PUNC80/160/320. I think in 11ax, it only applied to HE MU PPDU format. Are you assuming for MRU case of EHT TB PPDU, it should be categorized to punctured CH_BANDWIDTH?

è We might need clarification. As you mentioned, MRU is indicated in RU Allocation subfield in Trigger frame for each STA. Not to support punctured channel indication like EHT MU PPDU. However it does not mean not to support punctured CH_BANDWIDTH. So I left it as TBD. If I missed anything the group decided, let me know. If it is clear, then I will delete it.

To Edward,

Please include me as a TTT. Thanks.

regards
