SYSTEM AND METHOD FOR USING FREQUENCY RESOURCE IN A COMMUNICATION SYSTEM

摘要

A frequency resource usage system and a method thereof in a communications system capable of controlling ICI through simple adjustment operation are provided to reduce a problem about ICI(Inter Cell Interference) by using frequency resource by using segment sequence. A multi cell communications system uses frequency resource by using segment sequence. The usable frequency band is classified into the segments of A. One segment is classified into the sub bands of B. One sub band is classified into the channels of C. The order using the segment of A is shown by the segment sequence. The frequency assignment use sequence calls a segment sequence. The segment sequence is determined in consideration of ICI. The segment sequence is determined in consideration of the frequency reuse factor and sectorization coefficient in order to minimize ICI.
