Abstract: A method is provided for allowing a user equipment to receive data in a wireless communication system. The user equipment performs blind decoding for an enhanced physical downlink channel (EPDCCH) in which a downlink control information (DCI) is transmitted. The user equipment decodes data on a physical downlink shared channel (PDSCH) by using the DCI. If the DCI does not comprise demodulation reference signal information for decoding of the PDSCH, the PDSCH is decoded by using demodulation reference signal information associated with a resource block among a plurality of resource blocks in which the DCI is transmitted.

Abstract: A method and user equipment (UE) are provided for receiving control information through an enhanced physical downlink control channel (EPDCCH) in a wireless communication system. The UE indexes 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, and indexes the ‘n’ EREGs to ‘m’ enhanced control channel elements (ECCEs) per PRB pair. The UE determines an EPDCCH candidate constituting a UE-specific search space based on the ‘m’ ECCEs and performs blind decoding, 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 ‘m’ is determined by ‘n’ and a number of EREGs per ECCE.
