ABSTRACT:
A method including the steps of performing a synchronization measurement of a received signal (102), and performing a handoff (110) between a first communication channel and a second communication channel in response to the synchronization measurement. An apparatus including a receiver (50) detecting a received signal over a first communication channel, a receive signal processor (44) responsive to the receiver (50), and a handover controller (40) responsive to the receive signal processor (44). The receive signal processor performs a synchronization measurement of the received signal. The handover controller (40) initiates a handoff between the first communication channel and a second communication channel in response to the synchronization measurement.
