US 2019/0357143 A1 · METHODS FOR EFFICIENT MEDIUM ACCESS FOR WAKE UP RADIOS

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.

Dependent claims

A method performed by a station (STA) equipped with a wake-up radio (WUR) and a primary connectivity radio (PCR), the method comprising:

while the STA is in a sleep state, receiving on the WUR a wake-up frame (WUF) from an access point (AP), where the wake-up packet includes a WUF purpose field including a purpose indicator identifying one of a plurality of predetermined WUF purposes;
and
in response to the WUF, waking up the PCR and operating the PCR to communicate with the AP according to the purpose identified by the purpose indicator.

Dependencies are inferred from the claim text.
