Abstract

The present invention relates to a wireless communication system. In particular, the present invention relates to a method and apparatus for processing a downlink control channel with a terminal in a wireless communication system supporting carrier aggregation, and to a method and apparatus for receiving a reference signal for channel state information from a relay using a terminal in a wireless communication system, wherein the method for receiving a reference signal comprises the steps of: setting a transmission interval and offset for transmitting the reference signal; checking one or more subframes to receive the reference signal, on the basis of the transmission interval and offset; and periodically receiving the reference signal through said one or more subframes.
