Hi Rubayet I made some response to your comment. And it seems you did not go through my comment from p25 onwards. Please check those. BR. Atsushi. From: Rubayet Shafin <r.shafin@xxxxxxxxxxx>

Hi Rubayet Thank you for sharing PDT. I added some comment in attached file, please find it. BR. Atsushi. From: Pei Zhou <zhoupei36@xxxxxxxxx>
Hi
Rubayet, Thanks for your clarification. I understand that the allocated TXOP duration can be protected by MU-RTS TXS TF and CTS. Current text in your PDT is
“After sending the CTS …, the TXSPG non-AP STA… shall set the Duration/ID field of its following frames(s) to indicate a NAV end time that is no later than
….” I suppose it means that the TXSPG non-AP STA sets NAV to protect the allocated TXOP duration.
But before the TXSPG non-AP STA transmits its following frame(s), it may
“initiate an EDCA backoff procedure” as stated in the previous email.
My suggestion is that we may add description about the Duration/ID field setting of MU-RTS TXS TF. Because it is not clear whether the EDCA backoff procedure
is already protected. Best regards, Pei Zhou TCL 发件人: Rubayet
Shafin <r.shafin@xxxxxxxxxxx> Hi Pei, Thank you very much for reviewing the document. Appreciate it. A brief answer to your question is that TXSPG follows the baseline (11be) TXS procedure (35.2.1.2). Therefore, the entire duration of the TXOP allocated to the P2P group is protected by the NAV set
by other users, derived from the MU-RTS TXS trigger frame sent by the AP. So the other STAs won’t be able to jump in, according to the baseline rules. Elaborating a bit more-- when the Access Point (AP) transmits the MU-RTS TXS Trigger frame to the P2P group, this frame carries duration information. All STAs within the BSS that correctly receive
this Trigger frame are required to update their intra-BSS NAV based on this duration. This prevents other STAs from attempting to transmit during this period, thereby protecting the allocated TXOP from external contention. Furthermore, a non-AP STA that is
a member of the P2P addressed by the MU-RTS TXS Trigger frame shall transmit a Clear-to-Send (CTS) frame in response. This CTS frame, following the MU-RTS, further reinforces the NAV setting for any STAs that might not have heard the initial Trigger frame,
thereby further extending the protection of the TXOP across the BSS. Hope this clarifies. Please do not hesitate if you have any further comments or questions. Best Rubayet From: Pei Zhou <zhoupei36@xxxxxxxxx>
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 TCL 发件人: Jonghoe
Koo <jh89.koo@xxxxxxxxxxx> 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 Dear all, As shared by Rubayet and as described in the revision history of this document, we have made efforts to reflect as many technical comments
as possible that we have received after the first version of the P2P PDT document was shared. As part of these effort, numerous parts have been modified or removed. We kindly request that members actively share your feedbacks on the revised contents as well, so that the document can undergo sufficient
offline discussions and revisions before it is discussed. Any editorial and/or technical comments would be greatly appreciated.

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--
Co-CR:
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 To unsubscribe from the STDS-802-11-TGBN list, click the following link:
