1. A method of reporting channel state information (CSI) by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, through a higher layer signaling, information for configuring a plurality of CSI-reference signals (CSI-RSs),
wherein the information includes information on a periodicity which is commonly applied to the plurality of CSI-RSs transmitted in a time resource unit;
receiving the plurality of CSI-RSs within the time resource unit based on the information;
performing a channel measurement based on the plurality of CSI-RSs; and
reporting the CSI obtained based on a result of the channel measurement.
