Abstract
A communication unit comprises a receiver for receiving radio frequency (RF) signals from at least one wireless serving communication unit, and signal processing logic module arranged to decode information within the received RF signals is the at least one wireless serving communication unit. The signal processing logic module is further arranged to decode transmit power information in a received RF signal from the at least one wireless serving communication unit, and determine from the decoded transmit power information whether a transmission from the at least one wireless serving communication unit is suitable for use as a timing reference. If it is determined that the transmission from the at least one wireless serving communication unit is suitable for use as a timing reference, the communication unit synchronizes an operating frequency to the received RF signal of the at least one wireless serving communication unit.
