One embodiment of the present invention is a method for reporting channel state information by means of a terminal in a wireless communication system, the method comprising: a step of measuring a channel using at least one channel state information-reference signal (CSI-RS) indicated by at least one feedback type index from among a plurality of feedback type indices; and a step of generating channel state information based on the channel measurement and reporting the channel state information. Each of the plurality of feedback type indices indicates one or more CSI-RS configurations to be used in channel estimation and an effective channel relating to said one or more CSI-RS configurations.
