摘要： 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.

摘要： Provided are a method of transmitting a dedicated reference signal (DRS), a method of receiving a DRS, and a feedback method of a terminal. The method of transmitting a DRS includes determining a DRS transmitting resource for at least one terminal which is a target of transmission, and transmitting the DRS using the determined transmission resource and notifying the terminal of information about layer used by the terminal. The method of receiving a DRS includes determining a DRS receiving resource, receiving information about layer used by a terminal from a serving cell base station, and receiving the DRS for the terminal using the determined reception resource and the information about layer. Accordingly, a terminal can find the position and sequence of its DRS. In particular, in the case of multi-user multiple input multiple output (MU-MIMO) or joint scheduling, it is possible to prevent or remove signal interference using the DRS of another terminal.
