摘要： The present invention relates to a wireless communication system having at least one base station utilizing CoMP (Coordinated Multi-Point) transmission, wherein a terminal receives a reference signal from said at least one base station. If said at least one base station makes a transmission based on said reference signal through Coordinated beamforming (CB), information based on PMI (Precoding Matrix Index) corresponding to each base station is determined. Accordingly, if said at least one base station makes a transmission based on joint processing, phase set information is determined for phase correction of the formed beam. Thus, the present method transmits feedback information, comprising PMI set information based on CB and said phase set information, from said at least one base station to a server base station.
