Abstract:
Disclosed are a codebook-based signal transmission and reception method in a multi-antenna wireless communication system and an apparatus therefor. Specifically, a method for transmitting or receiving a signal on the basis of a codebook by a terminal in a 2-dimensional multi-antenna wireless communication system comprises the steps of: receiving a channel state information reference signal (CSI-RS) through a multi-antenna port from a base station; and reporting channel state information to the base station, wherein the channel state information may include a precoding matrix indicator (PMI) for indicating a precoding matrix, the PMI may include a first PMI for selecting a set of precoding matrixes from the codebook and a second PMI for selecting one precoding matrix from the set of precoding matrixes.

Claim (Index 11):
The method of  claim 2 , wherein the second matrix comprises one or more columns selected from a discrete Fourier transform (DFT) matrix generated by an equation below. D ( mn ) N v \u00d7 N v \ue89e Q v = 1 N v \ue89e e j \ue89e \ue89e 2 \ue89e \u03c0 \ue8a0 ( m - 1 ) \ue89e ( n - 1 ) N v \ue89e Q v , \n \ue89e m = 1 , 2 , \u2026 \ue89e , N v , n = 1 , 2 , \u2026 \ue89e , N v \ue89e Q v [ Equation ] wherein N_v is a number of antenna ports having identical polarization in a second dimension and Q_v is an oversampling factor used in the second dimension.
