Abstract
A method for performing, by a UE, precoding using a codebook in a wireless communication system includes: receiving a reference signal for channel estimation from an eNB; estimating a channel through the received reference signal; determining a precoding matrix related to the estimated channel in a codebook; and feeding back, to the eNB, a precoding matrix index (PMI) corresponding to the determined precoding matrix, wherein the codebook is generated in consideration of at least one of a region to which the UE belongs and the position of the UE.
