Hi Juseong,
Thanks for the contribution.
The best way to protect a R-TWT SP from OBSS occupation is Co-RTWT.
For those that are not protected by Co-RTWT, the AP can get access NPCA PCH prior to non-AP STAs by implementation (see 37.18.2 MU EDCA interaction with NPCA) when the
starting time of a R-TWT SP happens in an NPCA duration.
I’m not sure whether your proposal would help.

Subject: [STDS-802-11-TGBN] Regarding the SP text (Doc. 25/0645r1)
Hi all,
Today, I presented submission 25/0645r1(https://mentor.ieee.org/802.11/dcn/25/11-25-0645-01-00bn-r-twt-operation-with-npca.pptx) in the
TGbn MAC teleconference session, and I decided to defer the straw poll for now.
I plan to run the SP during the September F2F meeting session in Waikoloa.
I would like to hear your thoughts or questions regarding the SP text included in the submission.
The SP text is shown below.
SP #1: Do you support to add the following text to the 11bn SFD?
3.4 NPCA operation
Before starting transmission of any PPDU in the TXOP obtained on the NPCA primary channel, an NPCA STA should complete its frame exchange prior to the start of the R-TWT SP, as defined in subclause 35.8.4.1(TXOP and backoff procedure rules
for R-TWT SPs). If there is not enough time to complete its frame exchange prior to the start of the R-TWT SP, then the NPCA STA should defer transmission.
If you have any questions or comments on the SP text or the submission, please feel free to let me know.
Thank you.
Juseong Moon.
