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 7):
The method of  claim 6 , wherein the codebook is defined by the following equation 2. \ue89e [ Equation \ue89e \ue89e 2 ] W = \ue89e [ v p v p + q v p + 2 \ue89e q \u2026 v p + ( Q - 1 ) \ue89e q ] = \ue89e 1 M \ue8a0 [ v p \u2032 v p + q \u2032 v p + 2 \ue89e q \u2032 \u2026 v p + ( Q - 1 ) \ue89e q \u2032 v p + O \u2032 v p + q + O \u2032 v p + 2 \ue89e q + O \u2032 \u2026 v p + ( Q - 1 ) \ue89e q + O \u2032 v p + 2 \ue89e O \u2032 v p + q + 2 \ue89e O \u2032 v p + 2 \ue89e q + 2 \ue89e O \u2032 \u2026 v p + ( Q - 1 ) \ue89e q + 2 \ue89e O \u2032 \u22ee \u22ee \u22ee \u22f1 \u22ee v p + ( M - 1 ) \ue89e O \u2032 v p + q + ( M - 1 ) \ue89e O \u2032 v p + 2 \ue89e q + ( M - 1 ) \ue89e O \u2032 \u2026 v p + ( Q - 1 ) \ue89e q + ( M - 1 ) \ue89e O \u2032 ] wherein W represents the codebook, p represents the specific index, q represents the index spacing between code vectors, Q represents the number of code vectors included in the codebook, O represents the oversampling factor and M represents the number of antenna elements.
