Abstract: A method for reporting channel state information (CSI) from a user equipment to a base station in a wireless communication system is disclosed. The method comprises the steps of configuring a first feedback chain corresponding to a first channel state information-reference signal (CSI-RS) and a second feedback chain corresponding to a second CSI-RS through higher layer signaling; generating a first partial CSI and a second partial CSI corresponding to each of the feedback chains by using the first and second CSI- RSs received from the base station; periodically reporting the first partial CSI to the base station in accordance with the first feedback chain; and aperiodically reporting the second partial CSI to the base station in accordance with the second feedback chain.
