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 Transmit, to a station, a preamble of a wakeup signal, the preamble having a first bandwidth and including a wakeup — = message indicator indicating a transmission of a wakeup message of the wakeup signal identifier key to a station, and the station may determine a rotating identi- - \ , i 1905 fier associated with the AP based on the received identifier key. The sta- tion may receive a wakeup message from the AP, compare a sender iden- tifier with the rotating identifier, and power on a second radio. A station — _ = = \"V = Transmit the wakeup message of the wakeup signal to a wakeup radio of the station, the wakeup message having a may also receive a wakeup message that includes an indication of which station are to be activated. = second bandwidth narrower than the first bandwidth 1910 11 C:7 IN IN C C:7 © C \ ....
