Method and apparatus for coordinated communication

PURPOSE: A cooperative communications method and a device thereof are provided to effectively improve the communications performance of edge user equipment (UE). CONSTITUTION: A reception part receives sounding reference signal (SRS) receiving power information of each UE, which is included in a coordinator (710), with respect to each cell of schedulers (715,716) from each scheduler. A control part generates UE classification information, which is about whether the each UE is edge UE or not, based on the received SRS-receiving power information or signal-to-interference-plus-noise ratio (SINR) information estimated from the SRS-receiving power information. The control part generates interference relation information between the each UE and the each cell based on the received SRS-receiving power information or the estimated SINR information. A transmission part transmits the generated UE classification information and interference relation information to each scheduler.
