The present invention according to one embodiment is a control information receiving method wherein the method enables a terminal to receive control information through an enhanced physical downlink control channel (EPDCCH) in a wireless communication system, and comprises the steps of: indexing resource elements (RE) included in a physical resource block (PRB) set of a received subframe, as 'n' enhanced resource element groups (EREG) per PRB pair; indexing the indexed EREG as 'm' enhanced control channel elements (ECCE) per PRB pair; and determining EPDCCH candidates constituting a specific search space for a terminal on the basis of the indexed ECCE and performing blind decoding, wherein the number of EREG per PRB pair, 'n' is determined by considering at least one among the available RE number in PRB pairs, a structure of the subframe, and a type of carrier. |
