1. A method for wireless communication by a wireless communication device, comprising:
transmitting a frame over a wireless medium to an access point (AP), the frame including a medium access control (MAC) header and carrying a request for the AP to allocate part of a contention-based transmission opportunity (TXOP) obtained by the AP for peer-to-peer (P2P) communications between the wireless communication device and a client device;
receiving, from the AP over the wireless medium, a response frame that includes a MAC header carrying an acknowledgement of the request for the AP to allocate part of the contention-based TXOP obtained by the AP for P2P communications;
receiving, based at least in part on receiving the response frame, a trigger frame over the wireless medium from the AP, the trigger frame allocating a portion of the contention-based TXOP to the wireless communication device for the P2P communications; and
transmitting or receiving P2P data to or from the client device over the wireless medium during the allocated portion of the contention-based TXOP.
