Re: [STDS-802-11-TGBE] PDT-PHY-Pilots

Hi, Ron

Thank you for your comments.

I’ve modified the slides. Please see the attached (r1) and my reply as below.

 

  1. Sub-clause xx.3.10.10:
    1. Usage of single-stream pilot for partial BW UL MU-MIMO missing (only mode supported in 11ax). èMotion124 says that DL and UL MU-MIMO support at least for full BW. RU/M-RU support TBD. So I think it’s better to keep the words now. How about you?
    2. R matrix for EHT not yet defined (Already noted in the document) è I changed the words simply. (REHT-LTF is TBD). 
  1. Sub-clause xx.3.11.13: è I corrected most of all except 160/320MHz because in 11ax 160MHz, {pilot subcarrier indices in 80 MHz - 512, pilot subcarrier indices in 80 MHz +512} is used. So I think we use that _expression_ in 160/320MHz. Or do you want to be listed all?
    1. Table xx-1: Pilot indices for 26/52/106/242/484 RU in 80/160/320 MHz PPDU not explicitly listed (SFD motion text is reproduced verbatim). Suggest explicitly listing pilot indices for all PPDU BW
    2. Pilot sequence mapping: Referring to "Equation (27-101) to Equation (27-105) in 27.3.12.13" seems a bit imprecise. Suggest explicitly stating which equation in 11ax applies to which RU size
    3. Table xx-2: Pilot indices for 996 RU in 80M are correctly listed, however not explicit for 160M/320M PPDU BW. Suggest explicitly listing pilot indices for all PPDU BW.
    4. Table xx-3: Pilot indices for 2x996 RU in 160M are correctly listed, however not explicit for 320M PPDU BW. Suggest explicitly listing pilot indices for all PPDU BW
    5. "Noncontiguous 160+160 MHz transmission" - wording seems a bit different than 80+80 in 11ax. Suggest following 11ax wording, limited to 2x996 RU.

 

Best regards

Jinyoung

Hi TTT members and all,

I’ve uploaded the draft text for pilot. (https://mentor.ieee.org/802.11/dcn/20/11-20-1351-00-00be-pdt-phy-pilot.docx)

Please review it and give me some opinion.

 

 

 

Alfred,

Please add it in PHY agenda.

 

Best regards,

Jinyoung Chun

Hi TTT members and all,

This is for PHY-Pilot.

Actually there is no many texts for pilot. So I’d like to draft this section first and then discuss it with TTT members. I’ll share it soon.

If you have any suggestion, please let us know.

 

Best regards,

Jinyoung Chun
