Implementing wake-up radio (WUR) device communications

Abstract:

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for establishing communications with one or more devices. In one aspect, a first device generates a wake-up radio (WUR) frame, the WUR frame including a media access control (MAC) header and a frame check sequence (FCS) having a cyclic redundancy check (CRC) or a message integrity check (MIC). The first device may determine the FCS based, at least in part, on the MAC header and basic service set identifier (BSSID) information associated with the first device. The first device may output the WUR frame for transmission to one or more devices. A second device may receive the WUR frame from the first device and determine whether the WUR frame is directed to the second device based, at least in part, on comparing the FCS of the WUR frame with a calculated FCS.
