The present invention relates to a wireless communication system. According to one embodiment of the present invention, a method for transmitting, by a terminal, channel state inµformation (CSI) in a wireless communication system comprises the steps of: subsampling a code book for four antenna ports; and feeding back the CSI on the basis of the subsampled code book, wherein the CSI includes a rank indicator (RI) reported together with a precoding type indicator (PTI), and if the RI is greater than 2, the PTI is set to one.

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.
