Abstract
To reduce interference in a communication system (10), a communication unit (42-50) is arranged to initiate establishment of a radio frequency communication with a base station (26-38) by transmitting a system access request on a dedicated, wide area control channel. Upon receipt of the system access request, a base station (32) of the communication system of FIG. 1 responds by forming a narrowbeam control channel to the communication unit and transmitting system control information to the communication unit on the narrowbeam control channel, the system control information transmitted from the array of antenna elements and arranged to identify a narrowbeam communication resource for use in the radio communication. The communication unit (42-50), upon receiving the system control information, then configures itself to utilise the narrowbeam communication resource for the radio communication.
