Abstract
The aspects include a method or system that identifies, by an access point (AP), an idle window in a fast locate scan interval. The AP can schedule a Block Acknowledgement Request (BAR) for an idle Station (STA) in the idle window. The AP may then transmit the BAR in the idle window to the idle STA. In response to the BAR, the AP can receive a Block Acknowledgement (BA). The AP may then determine a characteristic about the BA, and, based at least on the characteristic, determine a location of the idle STA.
