Abstract: A method and device for monitoring a control channel in a wireless communication system are provided. In particular, in consideration of multiple carrier aggregation, indication information is provided which includes information on a cell for monitoring a downlink control channel and information on a channel type defined to identify whether a downlink control channel to be transmitted from a corresponding cell is a legacy PDCCH (LPDCCH) or an enhanced PDCCH (EPDCCH). The indication information may be set in consideration of whether to arrange cross carrier scheduling. Thus, a terminal uses the indication information to adaptively monitor LPDCCH and/or EPDCCH through a predetermined search section of a corresponding cell. Thus, it is possible to adaptively schedule a downlink control channel and an enhanced downlink control channel.
