<p>A wireless client device (108,110,112,200) associated with an access point (102) records (310) at which time T after a transmission time of a most recent beacon frame it gained access to the wireless medium (114) for transmission of an uplink packet to the access point. The wireless client device self-schedules target transmission times for future uplink packets, where each target transmission time is T after a respective expected transmission time of a beacon frame. Rather than immediately attempting to gain access to the wireless medium when it determines that another uplink packet is ready for transmission (314), the wireless client device waits (316) until shortly before its next upcoming target transmission time to make the attempt. Implementation in devices that are attempting to transmit uplink packets to the same access point may prolong the amount of time they can remain in a doze state, potentially reducing their power consumption.</p> |
