Abstract: A coordinated form of R-TWT SP scheduling taking into account the needs of non-AP STAs in adjacent BSS. A flag in the BSSID field is used to indicate if the AP is represented by the BSSID is a UHR AP. Mechanisms are described to support coordinated R-TWTs and the operation of UHR devices supporting these coordinated R-TWT. The protocol for UHR AP and UHR non-AP STAs allows for identifying possible interference with the OBSS, directly rescheduling, or performing negotiation with the UHR AP of the OBSS for scheduling the R-TWT SP.

Abstract: Providing conflict resolution between beacon transmission and Restricted-Target Wake Time (R-TWT) Service Periods (SPs) to enhance IEEE 802.11 protocols, especially for Extra High Throughput (EHT) Access Points (APs). After determining if a beacon will overlap the start of a TXOP and whether the beacon or R-TWT SP transmission has higher priority; the AP resolves the conflict such as to start or continue the R-TWT TID and embed the beacon frame within the transmitted frame, or to limit the TXOP to provide for transmitting the beacon frame at the proper timing.
