Abstract
Beacon-poll frames are transmitted from a station (STA) to a wireless AP in an opportunistic manner. In response to receiving a beacon-poll frame, the wireless AP transmits a unicast beacon frame to the STA, thereby eliminating the need for the STA to periodically wake up to receive broadcast beacon frames from the AP. The wireless AP may transmit the unicast beacon frame at a higher speed than a conventional broadcast beacon frame. As a result, the time that the STA must be awake to receive the unicast beacon frame is significantly less than the time that the STA must be awake to receive a conventional broadcast beacon frame, thereby resulting in significant power savings within the STA. The wireless AP may aggregate downlink (DL) data packets to be transmitted to the STA with the unicast beacon frame, resulting in further power savings within the STA.
