Hi, Jay.

Thank you for comment.

The SP 4 is not regarded between APs, but regarded between AP and the associated STA.

That is, the intention of SP4 is that the OBSS R-TWT is announced through the Beacon frame from AP to the associated STA.

Regards

SunHee Baek.

Hi SunHee,

Regarding to your SP4, if one AP share the OBSS info to another AP via Beacon frame, the two APs should share their BIGTK to each other to verify the received Beacon frame first.

Seems we don't have BIGTK sharing procedure between two APs. From security perspective, it's better to defer it now.

Thanks

Best Regards
