Hi Jonghoe and Rubayet,
Thanks for sharing this P2P PDT. I have one comment regarding the 37.16.1.3 Non-AP STA behavior.
In the last paragraph of page 9, “the non-AP STA … may initiate an EDCA backoff procedure for the transmission of one or more non-TB PPDUs …”.
If non-AP STA use EDCA backoff procedure here, which means the channel may be idle for a while, so how to make sure that the current TXOP not be contended by other STAs?
Best regards,
Pei Zhou

Hi Alfred,
Could you please indicate in the agenda that this document (P2P PDT doc 11-25/764) resolves 14 CIDs when adding it to the agenda?
The Abstract text box in the cover sheet of the uploaded document seems to be positioned in a way that obscures the list of CIDs that the document aims to address.
As attached, this document proposes resolutions for following 14 CIDs as part of CC50 comments:
229, 230, 849, 875 876, 1997, 2078, 2167, 2521, 2573, 3113, 3129, 3130, 3621

Subject: [STDS-802-11-TGBN] Updated P2P PDT
Hi Alfred,
Could you please add P2P PDT doc 11-25/764 to the MAC queue for SP?
Dear P2P TTTs,
Hope you all are doing well. I wanted to share some updates on the P2P PDT. Based on extensive discussions and feedback received from numerous members, either offline, online, or F2F (thanks to you all!), I have made significant changes to address the comments. One major change is that provisioning-related procedures have been entirely removed from the TXSPG for simplicity and ease of implementation. On the other hand, the Co-CR is now harmonized with the MAPC framework PDT. A summary of the changes is as follows—
TXSPG--
- Removed the Provisioning part and all provisioning-related procedures/frames/elements
- Added the MIB variable for TXSPG
- Added an entry for the definition of TXSPG in clause 3.2
- Removed Mode-3 based TXOP allocation procedure. Added text to reuse mode TXS Mode-2
- Added that only AP can assign the Group ID.
- Removed the new Direction field value (3—P2P group) in the QoS characteristics element; re-using value 2 (Direct Link)
- Added that only the TXSPG requesting STA can send the SCS request for the P2P group;
- Added that only the TXSPG requesting STA can return the TXOP
- Added that TXSPG shall follow the TXS fairness rules introduced in 11bn for CTDMA
- Changed the AID12 addressee to be the generic P2P group (AID12 = 2047);
Co-CR:
- Harmonized the text with the MAPC framework PDT (11-25/599r16--Giovanni).
- Moved to the subclause 37.13.2 (Procedures for specific multi-AP coordination schemes) the content of the detailed Co-CR operation between Co-CR requesting AP and Co-CR responding AP described in the subclause (Coordinated channel recommendation (Co-CR)) proposed by this document
- As a part of Co-CR profile, specified the format of MAPC Per-Scheme Info field and the format of the Co-CR Parameter Set field that is contained in the MAPC Request Parameter Set field
The revised PDT can be found here and is also attached. I would appreciate it if you could review the document and let me know whether you have any comments on the revised PDT.
Best
Rubayet
