A method for a terminal reporting channel state information (CSI) in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: receiving, from a base station, channel state information-reference signal (CSI-RS) setting information for receiving a CSI-RS resource; receiving the CSI-RS resource on the basis of the CSI-RS resource setting information; and reporting CSI generated on the basis of the CSI-RS resource to the base station, wherein when the same CSI-RS resource is set for repeated transmission for the terminal, the CSI-RS resource setting information may include indicating information relating to the location of a subcarrier on which the same CSI-RS resource is mapped.
