Abstract
A network element (230) for communicating with a wireless communication unit (214) in a communication cell (200) of a communication system (200) comprises a receiver arranged to perform a frequency sweep across a plurality of operational frequencies. Signal processing logic (255), operably coupled to the receiver, processes the received signals from the frequency sweep and providing an estimate of a level of interference at a number of frequency carriers of the swept frequencies. The signal processing logic (255) is capable of determining whether a transmit power level at a frequency selected from the processed frequency sweep satisfies at least one predetermined quality criterion of the communication system (200). A transmitter (270) is arranged, upon initial activation of the network element (230), to transmit to a wireless communication unit at the determined transmit power level.
