Abstract
A communication unit comprises receiver circuitry for receiving radio frequency (RF) signals from at least one wireless serving communication unit, and a signal processing logic module. The signal processing logic module is arranged to decode system information within received RF signals transmitted by the at least one wireless serving communication unit, determine whether the wireless serving communication unit supports a restricted access communication cell based on the decoded system information, and decide whether RF signals received from that at least one wireless serving communication unit are suitable as a timing signal source when synchronizing an operating frequency of the communication unit based at least partly on the determination.
