Abstract
One embodiment of the present invention discloses a method for allowing a terminal to transmit channel state information (CSI) in a wireless communication system in which a plurality of CSI reference signal (CSI-RS) resources are set for a plurality of transmission points, and the method for transmitting the CSI comprises the steps of: determining CSI reference resources; and transmitting CSI calculated from a measured signal on the basis of the CSI reference resources, wherein the CSI reference resources are included in one of at least two CSI subframe sets, the CSI subframe sets are set for each of the plurality of CSI-RS resources, and the CSI subframe sets are commonly set for transmission points which perform cooperative transmission among the plurality of transmission points.
