Abstract
A method for transmitting and receiving signals based on a codebook in a multi-antenna wireless communication system, the method comprising: transmitting a channel state information reference signal (CSI-RS); 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, the codebook being included in each code vector And a phase difference between adjacent elements may be set to be different from each other.
