Abstract

Disclosed herein are exemplary techniques for managing power in a direct wireless link between two wireless devices. The present invention provides at least three direct link power management techniques: Fast Resumption Mode (FRM) wherein the direct link is resumed automatically at a specified timing synchronization function (TSF); Slow Resumption Mode (SRM) wherein the direct link may be resumed by sending a Resume-Request via the access point; and Reverse Polling (RP), wherein one peer station of the direct link is continually awake and the other peer station uses reverse polling to start a service period. Thus, a method for power management of a direct wireless link between two wireless devices is disclosed. The method comprising the steps of establishing a direct wireless link between the first wireless device and the second wireless device; transmitting, from a first wireless device, a frame having a time value; receiving, at the second wireless device, the frame from the first wireless device; suspending the direct wireless link a duration determined based on the time value; and resuming the direct wireless link at a time determined based on the time value.
