Abstract
The present invention relates to a method for determining a precoding matrix for downlink signal transmission in a base station cooperative wireless communication system. The method includes receiving from a first terminal first channel information between the first base station and the first terminal, and second channel information between a second base station and the first terminal, transferring the first and the second channel informations to the second base station, determining a first precoding matrix for a first channel maximizing the efficiency of transmission to the first terminal, and determining, by the second base station, a second precoding matrix for a third channel between the second base station and the first terminal in order for a signal transmitted from the second base station to the first terminal to be arranged in an area where a signal transmitted from the first base station to the first terminal is not used.
