摘要： A method of power saving for a wireless transceiver (FIGS. 1 and 2) is disclosed. The transceiver has an active power mode (504) and a reduced power mode (510). The transceiver is operated in the reduced power mode (510) and monitors transmissions from a remote wireless transmitter while in the reduced power mode. The transceiver identifies a transmission from the remote wireless transmitter by a transceiver identity included in the transmission (FIG. 6. UE identification). The transceiver transitions to the active power mode (512) in response to identifying the transmission.
