    Abstract: Provided is a communication system for a multi-cell cooperative communication. A serving base station and at least one neighboring base station may communicate with at least one terminal through mutual cooperation. Each of the serving base station and the at least one neighboring base station may shift a phase of at least one element among elements included in a precoding matrix, using a phase shift matrix, and precode at least one data symbol. A terminal may feed back preferred phase shift matrix information to the serving base station, so that the serving base station and the at least one neighboring base station may adaptively determine a phase shift matrix. The terminal may calculate the phase shift matrix with small calculation amounts. The serving base station, the at least one neighboring base station, and the terminal may pre-store a plurality of candidate matrices with respect to the phase shift matrix.

    Abstract: Disclosed is a method for generating and transmitting a reference signal in a clustered DFT-spread OFDM transmission scheme. A method for generating and transmitting a DM-RS in a clustered DFT-spread-OFDM scheme comprises: a step of generating DM-RS sequences corresponding to the number of clusters allocated for an uplink transmission; and a step of mapping the generated DM-RS sequences to the relevant DM-RS symbol positions for each cluster. Accordingly, the method for generating and transmitting a reference signal according to the present invention, in which DM-RS sequences are allocated and transmitted on a cluster basis, uses a complete DM-RS sequence for each cluster, and therefore inter-cell interference can be weakened, and problems which might occur when applied to a multi-user MIMO (MU-MIMO) scheme can be solved.

    Abstract: The present invention relates to a cooperative communication method, in which a plurality of cells performs multiple antenna transmission and receiving cooperatively with each other in a cellular wireless system, and a terminal transmits channel state information (CSI) wirelessly to a serving cell and to at least one cooperative cell such that the serving cell and the cooperative cell use the CSI to perform multipoint communication. Although the serving cell and the cooperative cell may be of different base stations from each other, the transmission delay and traffic increase in a backhaul network can be prevented by minimizing information exchange between these cells.

Therefore, the data receiving device is able to estimate the channel exactly.
