Abstract:
Methods, systems, and devices for wireless communication are described. An access point (AP) may identify a jitter pattern for a wakeup message. A station may listen using a wakeup radio for a wakeup message during wakeup listening periods according to the identified jitter pattern. A station may receive a preamble having a first bandwidth and a wakeup message having a second bandwidth. An AP may transmit an identifier key to a station, and the station may determine a rotating identifier associated with the AP based on the received identifier key. The station may receive a wakeup message from the AP, compare a sender identifier with the rotating identifier, and power on a second radio. A station may also receive a wakeup message that includes an indication of which station are to be activated.
