Method for receiving downlink control information in wireless access system and terminal therefor

A user equipment (UE) receiving downlink control information (DCI) in a wireless access system, the UE comprising:

• an RF unit configured to transceive radio signals;
• and
• a processor configured to:
• perform blind decoding according to a transmission mode set for the UE in a search space assigned to the UE, and
• control the RF unit to receive the DCI via a physical downlink control channel (PDCCH) identified by the blind decoding,
• wherein the set transmission mode is one of a plurality of transmission modes supported by a base station (BS) that are restricted according to performance of the UE, and
• wherein the blind decoding is performed using only half of total M control channel elements (CCE) aggregation levels for the search space, when the UE performs a machine type communication (MTC), where M corresponds to ‘4’ or ‘2’.
