An embodiment of the present invention relates to a method for receiving a control signal through an enhanced physical downlink control channel (EPDCCH) by a user equipment in a wireless communication system, the method comprising: receiving a demodulation reference signal (DMRS) included in a physical resource block (PRB) pair; and monitoring an EPDCCH associated with the DMRS, wherein a minimum aggregation level or the number of enhanced resource element groups (EREGs) per enhanced control channel element (ECCE) applied to the EPDCCH is determined depending on to which interval of a plurality of predetermined intervals the number of resource elements (REs) included in the PRB pair belongs.
