A method by which a user equipment receives a downlink control signal in a wireless communication system supporting carrier aggregation (CA) and coordinated multiple-point transmission and reception (CoMP), according to one embodiment of the present invention, comprises the steps of: receiving candidate sets of control information for the CA and the CoMP from a downlink serving base stations; and receiving an indicator for indicating one of the candidate sets from the downlink serving base station, wherein the candidate sets of the control information comprise a usable set of control information with respect to each carrier wave, and the control information can include information on carrier waves scheduled by the downlink serving base station, information on channel state information-reference signal antenna port(s) that is (are) quasi co-located (QCL) assumable with demodulation-reference signal antenna port(s) of the downlink serving base station, information on PDCH resource element (RE) mapping and/or information indicating whether or not QCL assumption between the channel state information-reference signal antenna port(s) and antenna port(s) indicated by the information on PDSCH RE mapping is possible.
