METHOD FOR TRANSMITTING SIGNAL IN MULTI-ANTENNA WIRELESS COMMUNICATION SYSTEM AND APPARATUS FOR THE SAME

摘要

The present invention relates to a method for a base station transmitting a precoded signal to user equipment in a wireless communication system supporting a multi-antenna. More specifically, precoding is conducted by using a precoding matrix to which large delay-cyclic delay diversity (LD-CDD) is applied, wherein the precoding matrix is determined by dividing into matrices for a horizontal direction antenna and a perpendicular direction antenna.

1. A method for transmitting, by a base station, a signal in a wireless communication system, comprising:
precoding a signal using a matrix for precoding; mapping the precoded signal to resource elements; and transmitting the mapped signal to a user equipment (UE), wherein the matrix for precoding is calculated on a basis of a matrix for horizontal antennas of the base station and a matrix for vertical antennas of the base station, wherein the matrices for the horizontal antennas and the vertical antennas respective have cyclic delay values.
