Original Abstract Submitted
A station (STA) receives from an access point (AP) a frame indicating a start time and a wake duration of a restricted target wake time (r-TWT) service period (SP) of an r-TWT setup for the STA. The STA transitions to an awake state at or before the start time of the r-TWT SP. The STA receives, from the AP, during the r-TWT SP: a first frame comprising a traffic identifier (TID) associated with the r-TWT and having an end of service period (EOSP) field set to 0; or a trigger frame indicating an identifier of the STA. The STA transitions to a doze state, after expiration of the wake duration of the r-TWT SP, on condition of receiving, from the AP, after expiration of the wake duration of the r-TWT SP, a second frame comprising a TID associated with the r-TWT and having an EOSP field set to 1.
