Abstract
An access point device comprising a transceiver configured to receive and send messages on a communication channel, and a controller configured to cause the transceiver to transmit beacon messages regularly on the communication channel is disclosed. The beacon messages include a first indication that data, for one or more stations arranged to communicate with the access point device over the communication channel, is buffered in a buffer associated with the access point device when data is buffered in the buffer. The transceiver is arranged to transmit at least one utility message, transmitted over the communication channel between transmissions of the beacon messages, wherein the at least one utility message comprises a second indication for at least one of the one or more stations as to whether an upcoming beacon message comprises the first indication that data for the at least one of the one or more stations is buffered in the buffer. The station is arranged to communicate over the communication channel with the access point device, and arranged to apply a power save mode including a Doze state and an Awake state, wherein, when the station is in the Doze state, the station occas…
