Abstract:
Disclosed are a codebook-based signal transmission/reception method in a multi-antenna wireless communication system, and a device for same. Specifically, provided is a method by which a terminal transmits/receives a signal on the basis of a codebook, in a 2-dimensional multi-antenna wireless communication system, comprising the steps of: receiving a channel state information reference signal (CSI-RS) from a base station, via a multi-antenna port; and reporting channel state information to the base station. The channel state information comprises a precoding matrix indicator (PMI) for indicating a precoding matrix. The PMI comprises a first PMI for selecting a precoding matrix set from a codebook, and a second PMI for selecting one precoding matrix from the precoding matrix set. The pair of the first dimensional index and second dimensional index of the precoding matrix belonging to the precoding matrix set is (x, y), (x+2, y), (x, y+1), (x+1, y+1), x and y being whole numbers that are not negative.

Claim (Index 9):
A method for transmitting and receiving a signal by an eNB based on a codebook in a 2-dimensional multi-antenna wireless communication system, the method comprising:\n transmitting a CSI-RS to a UE through multiple antenna ports; and receiving channel state information from the UE, wherein the channel state information includes a precoding matrix indicator (PMI), the PMI includes a first PMI for selecting a precoding matrix set from the codebook and a second PMI for selecting a precoding matrix from the precoding matrix set, pairs of indexes of a first dimension and indexes of a second dimension of precoding matrices belonging to the precoding matrix set are (x,y), (x+2,y), (x+1,y+1) and (x+3,y+1), and x and y are integers which are not negative numbers, wherein the codebook is composed of a precoding matrix generated based on the Kronecker product of a first matrix for first dimension antenna ports and a second matrix for second dimension antenna ports, and the first matrix is specified by a first dimension index of the precoding matrix and the second matrix is specified by a second dimension index of the precoding matrix.
