Abstract

See full text

A device for communicating in a wireless network, such as, for example, a non-AP STA, is adapted to send a trigger frame to an AP for group-addressed frames. In addition, an AP may be adapted to be triggered for group-addressed frames to deliver the group-addressed frame to a non-AP STA. The group-addressed frames could include data frames or management frames or both. Such a device or non-AP STA can advantageously stay in a power save mode until it is ready to wake up to send a trigger frame to the AP, and does not need to wake up at regular intervals, such as at every DTIM time interval, to listen for beacons from the AP and to receive any group-addressed frames destined for it and buffered at the AP. In this way, the battery life of the device may be extended.
