1. A method performed by a wireless communication device, comprising:
performing a channel sensing operation that indicates whether a wireless channel is busy or idle; and
transmitting, at a first time, a first packet over a wireless channel associated with a restricted target wake time (TWT) service period (SP) responsive to the channel sensing operation indicating that the wireless channel is idle for a threshold duration relative to a start of the restricted TWT SP, the first packet including a duration field indicating a duration that the wireless channel is reserved, wherein the duration corresponds to a first portion of the restricted TWT SP, wherein a second portion of the restricted TWT SP following the first portion is available for contention by any of one or more first devices that are members of the restricted TWT SP and one or more second devices that are non-members of the restricted TWT SP.
