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