Method for relaying of relay having multiple antenna in wireless communication system

PURPOSE: A relay method of a relay with a multiple antenna in a wireless communication system performing scheduling in a source station is provided to increase the quality of the signal transmission by setting up the entire channel state. CONSTITUTION: A repeater processes the signal of a source station through a mid coding matrix(S100). The mid coding matrix defines the connection structure between one or more transmission antenna with one or more antenna of relay. The relay transmits processed signal to a target station(S110). The source station performs scheduling through the proper adjustment of the mid coding matrix.
