Embodiment Construction

[0020] refer to figure 1 , a block diagram of a communication system 10 according to a preferred embodiment of the present invention is defined by a plurality of adjacent cells 12-24 (conventionally represented by hexagons). Each cell 12-24 includes centrally located base station means 26-38 to optimize the communication coverage area of ​​each cell and includes an adaptive array of antenna elements. In this description, the general term "base station device" will be used to refer to a base station controller, base station transceiver or a suitable combination, and to denote a voice or data communication device (usually A communications unit of control logic arranged to operate on radio frequencies and to route calls between them.

[0021] Communication units 42 - 50 , such as mobile telephones and mobile data units 42 - 44 , are dispersed throughout the geographic area of ​​communication system 10 . The mobile communication units 42-44 are able to move across the boundaries...

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 Figure 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.

Description

technical field [0001] The present invention generally relates to a communication system with a beamforming control channel, and more particularly to a system control method in a communication system with an adaptive antenna array. Background technique [0002] A cellular communication system is usually composed of a number of adjacent "cells", each cell being managed by a base station controller. Typically, each base station controller will control a number of base transceiver stations, with each transceiver responsible for managing a single sector within each cell. A mobile unit attached to a particular system (perhaps a time-division or frequency-division system) is free to move between cells and in either case primarily only one base transceiver station controls its communications in time so that when the mobile unit crosses adjacent Nominal boundaries between sectors or cells, each mobile unit is subject to an override between base transceiver stations (and occasionall...
