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.

Abstract: Methods and apparatus for an electronic device to perform a dynamic frequency selection (DFS) proxy function are described. An interface circuit of the electronic device receives, from an access point associated with the electronic device, a frame with DFS information that indicates a presence of interference associated with a higher priority user in a shared band of radio frequencies. The frame can include an action frame with a channel switch announcement (CSA) or a beacon with a CSA. In response to receiving the DFS information, the electronic device forwards, to a third electronic device, the DFS information, where the third electronic device is not associated with and does not have a connection to the access point. In this way, the electronic device functions as a DFS proxy for the third electronic device with respect to the shared band of radio frequencies used by the access point.
