METHOD OF DATA TRANSMISSION BASED ON MULTI-CELL COOPERATION

摘要

PURPOSE: A method for transmitting data based on multi-cell cooperation is provided to implement fast data processing by reducing the burden of a back-hole network and a feedback from a terminal. CONSTITUTION: A CQI(channel quality indicator) is received from each terminal within a cell, and candidate terminals are selected based on the CQI(S310). A serving PMI(Precoding Matrix Index) for a serving base station, a neighboring PMI for a neighboring base station, a CQI obtained from the serving PMI and the neighboring PMI are received from each candidate terminal(S320). A transmission terminal and a transmission PMI to be used for data transmission are selected based on the CQI, the neighboring PMI and the serving PMI(S330). Data are transmitted to the transmission terminal by using a precoding matrix indicating the transmission PMI(S340).
