Abstract

The present invention relates to wireless communication, and more particularly, to a method for transmitting a signal using a plurality of antenna ports and a transmission end apparatus for same. According to a method for a transmission end transmitting the signal in a multi-input multi-output (MIMO) wireless communication system of the present invention, a step of transmitting instruction information on a first channel transmission method to a reception end, and a step of transmitting the first channel to the reception end using a resource region are comprised, wherein the first channel is either an advanced-physical downlink control channel (A-PDCCH) or a relay-physical downlink control channel (R-PDCCH), the first channel is not transmitted when at least a portion of the resource region overlaps with a resource region used for transmitting a second channel, and wherein the second channel can be periodically transmitted using a predetermined portion of the resource region.
