Disclosed are a terminal device for receiving a signal in a wireless communication system for supporting a plurality of component carriers and a method thereof. In the terminal device for receiving the signal in the system for supporting the component carriers, a receiver receives a Physical Downlink Control Channel (PDCCH) including control information of a first type component carrier from a base station or a relay. A processor performs a decoding operation or controls an operation in a slip mode on the basis of control information included in a PDCCH in a second type component carrier after a time corresponding to a particular time offset value passes from a transmission time point of the PDCCH.
