Abstract
A communication unit is capable of communicating in a wireless communication network. The communication unit comprises a receiver for receiving timing signals from a plurality of serving wireless communication units; a frequency synchronizing circuit operably coupled to the receiver for synchronizing an operating frequency of the communication unit to a serving wireless communication unit of the plurality of serving wireless communication units Control logic is capable of controlling the frequency synchronizing circuit to adjust an operating frequency of the communication unit. The control logic is arranged to distinguish between macro cell transmissions and femto cell transmissions and in response thereto selectively use or reject timing signals from the plurality of serving wireless communication units in adjusting the operating frequency of the wireless communication unit.
