Abstract: Methods and apparatuses for facilitating extension of the duration of a target wake time (TWT) service period (SP) for TWT operation of wireless devices in a wireless local area network (WLAN). A station (STA) device comprises a transceiver and a processor operably coupled to the transceiver. The transceiver is configured to establish a TWT schedule with an access point (AP), the TWT schedule having a TWT SP with a duration that ends at a nominal SP end time, and to remain in an awake state for the duration of the TWT SP. The processor is configured to determine to extend the duration of the TWT SP to a new SP end time that is after the nominal SP end time.

Abstract: Methods and apparatuses for facilitating restricted target wake time (TWT) operation on peer-to-peer (P2P) links in a wireless local area network. A wireless station (STA) apparatus comprises a transceiver and a processor operably coupled to the transceiver. The transceiver is configured to receive, from an access point (AP), a restricted TWT schedule and an indication of whether the restricted TWT schedule can be used for P2P communication. The processor is configured to establish a P2P link with a peer STA, and use the restricted TWT schedule for communication over the P2P link based on a determination, from the indication, that the restricted TWT schedule can be used for P2P communication.
