Abstract
Methods and systems are described for efficient medium access in wake-up radios. In an exemplary embodiment, a wake up frame (WUF) includes fields indicating a wake-up purpose, wake-up scheduling, and a wake-up TX/RX parameter. The wake-up purpose field identifies one of a plurality of predetermined purposes. A STA receives the wake-up frame and determines whether the frame is intended for that STA. If so, the STA responsively performs an action in accordance with the purpose indicated in the purpose field. Purposes that may be indicated in the WIF purpose field may include Listen to Beacon, Uplink Data Transmission, Downlink Data Transmission, and (Re)Association, among others.
