1. A method for wireless communication by an access point (AP), comprising:
receiving a request frame from a wireless station (STA) associated with the AP and also associated with a client device via a peer-to-peer (P2P) link, the request frame indicating that the STA intends to exchange P2P communications with the client device during a restricted target wake time (r-TWT) service period (SP) scheduled on a wireless medium, the request frame identifying the client device;
transmitting a response frame, responsive to receiving the request frame, on the wireless medium to the STA;
obtaining a transmission opportunity (TXOP) on the wireless medium during the r-TWT SP; and
transmitting a trigger frame on the wireless medium responsive to obtaining the TXOP, the trigger frame allocating a portion of the obtained TXOP for P2P communications between the STA and the client device, wherein at least one of the response frame or the trigger frame indicates a Network Allocation Vector (NAV) exception for the client device.
