Abstract
Provided is a base station for operating a Cooperative Multi-Points Transmission and Reception (CoMP). A base station of a serving cell may perform scheduling according to an Inter-cell Interference Coordination (ICIC) scheme from a point in time when a service is provided to a user equipment (UE). When a Precoding Matrix Index (PMI) coordination is required, the base station of the serving cell may perform the PMI coordination in interoperation with a neighboring cell. In addition, when a status of the UE satisfies a particular condition, the base station of the serving cell may perform the aforementioned ICIC scheme and the PMI coordination. Also, the base station of the serving cell may perform the aforementioned ICIC scheme and the PMI coordination together.
