Abstract
Disclosed are an apparatus and method for transmitting/receiving control information in a wireless communication system that supports carrier aggregation. According to the present invention, a processor of a base station device that transmits control information configures a component carrier type for each of a plurality of downlink component carriers (DL CCs) in accordance with whether or not each of the plurality of DL CCs can support a relay PDCCH (R-PDCCH), which is a downlink control channel dedicated to a relay node. A transmitting antenna transmits information on the type of each of the configured DL Cs to the relay node.
