Is performed by the base station, there is provided a data transmission method based on a multi-cell cooperation. The method serving for the at least one CQI step, the serving base station from the candidate terminal for selecting a plurality of candidate terminals to the step, based on the received CQI for receiving (channel quality indicator) from each mobile station in the cell PMI (precoding matrix index), neighboring PMI and the serving PMI and the adjacent receiving a CQI obtained from the PMI, wherein each of the received serving from the candidate terminal PMI, neighboring PMI and based on the CQI transmission terminal and the data transfer to the adjacent base station selecting a PMI to be used for transmission, and using the precoding matrix to which the PMI transmission instruction includes transmitting the data to the transmission terminal. Reducing the feedback from the terminal for the implementation of multi-cell cooperation, and can also reduce the burden on the network backhaul.
