Method for reporting channel state information in wireless communication system and device therefor

A user equipment (UE) for reporting channel state information (CSI) in a wireless communication system, the UE comprising:

• one or more antennas configured to transmit and receive a radio signal;
• and
• a processor configured to:
• transmit, to a base station, UE capability information including information for a maximum number of channel state information-reference signal (CSI-RS) resources, receive, from the base station, CSI-RS configuration information via a higher layer signaling,
• receive, from the base station, a channel state information-reference signal (CSI-RS) on at least one CSI-RS port based on the CSI-RS configuration information,
• measure a channel based on the CSI-RS, and
• report, to the base station, a result of the channel measurement.
