1. A method for wireless communication by a wireless communication device operating as an access point (AP), comprising:
establishing a restricted target wake time (TWT) session on a wireless channel, the restricted TWT session including at least one restricted TWT service period (SP) for peer-to-peer (P2P) communications;
admitting a group of wireless stations (STAs) associated with P2P communications as members of the restricted TWT session;
obtaining a transmission opportunity (TXOP) on the wireless channel during the at least one restricted TWT SP; and
transmitting, on the wireless channel, a protection frame identifying one or more STAs of the group of STAs belonging to the restricted TWT session that are permitted to transmit or receive P2P communications on the wireless channel during the TXOP, the protection frame indicating to devices other than the one or more identified STAs that the wireless channel is unavailable for at least a portion of the TXOP.
