Abstract
Disclosed are a method for reporting channel state information in a wireless communication system and an apparatus therefor. A method by which user equipment reports 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, an RRC message including at least one CSI-reference signal (CSI-RS) configuration for a first direction domain; respectively receiving through different subframes, a first CSI-RS from a first subset and a second CSI-RS from a second subset among a plurality of physical antenna elements in the base station on the basis of the CSI-RS configuration; and performing a CSI report by using the first and second CSI-RSs, wherein when the CSI-RS configuration for the first direction domain is one, the first CSI-RS and the second CSI-RS are respectively received from the first subset and the second subset by virtualization-varying antenna ports related to one CSI-RS configuration in a predetermined period.
