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 5):
The method of  claim 1 , wherein:\n a pair of first-dimensional index and second-dimensional index of a precoding matrix within the set of precoding matrices are (x,y), (x+1,y), (x+2,y), and (x+3,y), and the x and y are integers other than a negative number.
