Claim Text:
1. A method for receiving control information through an enhanced physical downlink control channel (EPDCCH) at a user equipment (UE) in a wireless communication system, the method comprising: indexing, by the UE, resource elements (REs) included in a physical resource block (PRB) set of a received subframe with ‘n’ enhanced resource element groups (EREGs) per PRB pair; indexing, by the UE, the ‘n’ EREGs to ‘m’ enhanced control channel elements (ECCEs) per PRB pair; and determining, by the UE, an EPDCCH candidate constituting a UE-specific search space based on the ‘m’ ECCEs and performing blind decoding, wherein when a size of an EREG is fixed, ‘n’ is determined based on a number of REs available for a PRB pair and the size of the EREG, and wherein ‘m’ is determined by ‘n’ and a number of EREGs per ECCE.
