METHOD FOR EXECUTING COMP

摘要

PURPOSE: A CoMP performing method is provided to share inter-cell channel state information by a coordinated scheduling scheme/beamforming scheme among CoMP method of a terminal, thereby reducing inter-cell interference. CONSTITUTION: A terminal request performance of relevant CoMP(Coordinated Multi-Point) method to cells relevant to intra BS(Base Station) and cells relevant to inter BS(S320). The terminal selects PMI(Precoding Matrix Indication) and CQI(Channel Quality Indicator) information from the cells. The terminal transmits the selected information to a serving cell(S330). The serving cell transmits one or more of the worst PMI information to the cells corresponding to the inter BS. The serving cell transmits one or more of the best PMT or the big influence of PMI, CQI information about the terminal transmits to cells corresponding to the intra BS(S340).
