Background

Coordinated R‑TWT (Co‑R‑TWT) seeks to provide reliability by sharing restricted service periods across overlapping BSSs so that neighboring APs can mutually protect time‑sensitive transmissions.

Although the operation concept is outlined, the concrete negotiation and advertisement mechanisms between APs are explicitly stated as not yet defined.

References

To enable Co-R-TWT, the two APs must negotiate an RTWT schedule by exchanging frames, either existing or newly defined management frames (to this date, the specific negotiation and advertisement of RTWT schedules between APs has not been defined).
