A communication system performing a coordinated multipoint transmission is provided. A mobile station may measure expected channel quality information when an interference of a serving base station does not exist. The serving base station may determine whether a neighbor base station and the serving base station are eligible to perform the coordinated multipoint transmission. The serving base station may determine whether the neighbor base station and the serving base station are eligible to perform the coordinated multipoint transmission using a criterion associated with an evaluation of an increase in a transmission rate of the mobile station.
