The present invention relates to a method for a terminal to transmit channel state information in a multi-cell cooperative wireless communication system. Particularly, the method comprises the steps of: determining a precoding matrix index (PMI) for a serving cell from among a plurality of PMIs; structuring PMI information for a cooperative cell based on the PMI for the serving cell; and transmitting the PMI for the serving cell and the PMI information for the cooperative cell to the serving cell, wherein a plurality of the PMIs are divided into a plurality of PMI subsets, PMIs included by the respective PMI subsets are vertically placed, and the PMI information for the cooperative cell comprises a first indicator indicating at least one of a plurality of the PMI subsets to a PMI subset for the cooperative cell, and a second indicator indicating at least one of the PMIs in the indicated PMI subset to the PMI for the cooperative cell. |
