APPARATUS AND METHOD FOR ELIMINATING INTER CELL INTERFERENCE IN A MULTIPLE INPUT MULTIPLE OUTPUT WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: An apparatus and a method for eliminating inter-cell interference in a multiple input multiple output wireless communication system are provided to select a PMI(Precoding Matrix Index) according to a priority set by a priority index, thereby efficiently eliminating inter-cell interference. CONSTITUTION: The channel quality about a serving base station is measured(201). If the channel quality is lower than a threshold value, interference power received from neighboring base stations is measured(203). PMIs and priority indexes about each neighboring base station are calculated(205). At least one of the PMI, PMI type indicator, the priority indexes and the channel quality is fed back to the serving base station(207).
