In one embodiment of the present specification, provided is a method for receiving control information on an enhanced physical downlink control channel (EPDCCH). The method for receiving control information may comprise the steps of: receiving information associated with a pattern change of a demodulation reference signal (DMRS); identifying a time of changing mapping between an enhanced resource element group (EREG) and an enhanced control channel element (ECCE) for an EPDCCH, according to the pattern change of the DMRS; and receiving control information on the EPDCCH by applying the change of the mapping at the identified time.
