Abstract: A station, a method performed by a station and a corresponding method performed by an access point (AP) of a network to allow the station to operate a wireless local area network (WLAN) radio in a sleep state until the WLAN radio is ready to receive a beacon from the AP. The station includes a low power (LP) radio configured to receive a wake up signal from an AP of a network to which the station is connected. The station further includes a WLAN radio configured to operate in a sleep state until the WLAN radio receives an indication from the LP radio that the wakeup signal has been received, wherein WLAN radio is further configured to operate in a fully awake state after receipt of the indication to receive a beacon from the AP indicating a data transmission is pending for the station.
