Abstract: An apparatus determines a wireless traffic load; generates at least one timer value based at least in part on the determined traffic load; and initiates a wireless transmission at a time based at least in part on the at least one timer value. The at least one timer value indicates a time for initiating a transmission after changing from a lower power state to a higher power state. In an exemplary embodiment the wireless traffic load is determined via continuous monitoring and initiating the transmission includes obtaining a transmission opportunity for sending a trigger frame or a power save poll frame. Various exemplary techniques are detailed as to how to determine the traffic load. The generated at least one timer value is a maximum time, which may be truncated for example after the apparatus receives a data unit by which to obtain a network allocation vector.
