Abstract

The present invention relates to a wireless communication system, and more particularly, discloses a method and apparatus for signaling control information on transmission methods in a wireless communication system that supports multi-antenna transmission. According to one embodiment of the present invention, a method in which user equipment receives, from a base station, a downlink channel in a wireless communication system that supports a multi-antenna transmission, comprises: a step of transmitting, to the base station, a function indicator for a downlink channel receiving function generated by a transmission mode using four transmission antennas; a step of acquiring control information for the transmission mode using one or more transmission antennas for each of a downlink control channel and a downlink data channel; and a step of receiving each of the downlink control channel and the downlink data channel using the control information, wherein said control information can be determined by the function indicator.
