Re: [STDS-802-11-TGBE] Modified text of PDT-PHY-Packet-Extension



Hi Yan,

 

Thanks for following up on this.

 

Just a small comment , In “PE duration should be described in HE PHY capabilities subfield “Nominal Packet Padding”,”,

I think you mean EHT PHY capabilities.

 

Regards,

Hi all,

 

   Based on the comments raised regarding the allowed transmission modes with 20us PE duration. My modifications are highlighted in yellow.

 

A PE field of duration 20 µs is only allowed in an EHT PPDU with at least one participating STA being modulated with 4096-QAM, or in an EHT PPDU with more than 8 spatial streams transmitted on at least one RU/MRU, or in a 320 MHz EHT MU PPDU if the size of the one of the allocated RU or MRU is greater than 2x996, or in a 320MHz (TBD) EHT TB PPDU.

 

  I don’t think we need to talk about non-AP STA support of 20us transmit/receive in this section. Non-AP STA support of transmit/receive 20us PE duration should be described in HE PHY capabilities subfield “Nominal Packet Padding”, and PPE Thresholds field section, as in 11ax. Besides, I don’t think the statement above indicates every non-AP STA has to support 20us PE duration since AP can schedule the non-AP STAs in EHT MU PPDU or EHT TB PPDU according to their PE support indications.

 

  In this section, we just clarify what the specific properties are required for an EHT PPDU to be allowed to transmit with 20us PE duration.

 

  The statement an EHT PPDU with at least one participating STA being modulated with 4096-QAM, or in an EHT PPDU with more than 8 spatial streams transmitted on at least one RU/MRU covers EHT MU PPDU with OFDMA, or MU-MIMO, and EHT TB PPDU with OFDMA, or MU-MIMO, and EHT MU PPDU with only one STA.

 

  Please let me know if you have other concerns.

 

Thanks

Yan
