Abstract: Some embodiments include an apparatus and method for a mobile access point (AP) station that operates in an always-on soft AP mode where a station is associated with the mobile AP station, and switch back to operate as a station in an infrastructure mode with an AP. For example, in an always-on soft AP mode, the mobile AP station may implement a target wake time (TWT) responder power save mode feature. The mobile AP station may maintain a wake window after a beacon to enable unassociated devices to associate; establish a broadcast TWT schedule for unassociated TWT-capable devices to associate; schedule TWT for associated devices; go to sleep outside of the scheduled TWT of the associated devices; and switch back to infrastructure mode to perform as a station and maintain a connection with an AP.

Abstract: Some embodiments include an apparatus and method for enabling concurrent peer-to-peer (P2P) communications via a scheduled resource unit (RU) allocated by an access point (AP). For example, the AP may use a trigger frame to schedule uplink (UL) multi-user (MU) access for a first station of a plurality of stations by allocating an RU to the first station. Instead of using the allocated RU for UL infrastructure communications with the AP, the first station may utilize the allocated RU for a P2P communications with a second station. In some embodiments the AP facilitates RU utilization for P2P communications between stations. In some embodiments, the first station uses the allocated RU and the AP may be unaware of the P2P communications.
