Abstract:
A method for transmitting/receiving signals by a UE based on a codebook in a multi-antenna wireless communication system according to an aspect of the present invention includes: receiving a channel state information reference signal (CSI-RS) from a base station through multiple antenna ports; and reporting channel state information to the base station, wherein the channel state information includes a precoding matrix indicator (PMI) for indicating a specific code vector among a plurality of code vectors included in the codebook, wherein elements included in each code vector included in the codebook are selected from elements of a predetermined circular vector using an azimuth angle of the UE with respect to the base station and an oversampling factor.

Claim (Index 5):
The method of  claim 3 , wherein the first index of the starting code vector of the codebook is determined based on a specific index of an element corresponding to the azimuth angle of the UE for the base station among the elements of the predetermined circular vector, an index spacing between code vectors and the number of code vectors included in the codebook.
