ABSTRACT:
Each of a plurality of base stations in a mobile radio communication system has a plurality of sectoral zones each having a directional antenna of horizontal directivity pattern. Radio channels are divided into as many groups as the number of sectoral zones per base station. The channel groups are assigned to the sectoral zones as the preferential allocation channel groups in such a manner that the same channel groups are assigned to the sectoral zones which have substantially the same directions determined by antenna directivity. When a request for communication occurs within a sectoral zone, channels are selected from the channel group assigned to the sectoral zone. If the carrier-to-interference power ratio of a selected channel is equal to or greater than a predetermined value, the selected channel is allocated. The mobile radio communication system thus has improved channel utilization efficiency to accommodate more traffic.
