Abstract
Provided is a coordinated communication method in which a plurality of cells cooperate to perform multi-antenna transmission and reception in a cellular wireless communication system. A terminal wirelessly transmits channel state information (CSI) feedback to a serving cell and at least one coordinating cell. The serving cell and the coordinating cell perform multi-point coordinated communication using the CSI feedback. Even if the serving cell and the coordinating cell belong to different base stations, information exchange between the cells is minimized, so that a transmission delay and a traffic increment of a backhaul network can be prevented.
