1. A method for receiving control information at a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, at the UE, a subframe including an enhanced physical downlink control channel (EPDCCH); and
monitoring, at the UE, a set of EPDCCH candidates at each aggregation level of an aggregation levels set,wherein the aggregation levels set is set differently according to the number of Resource Elements (REs) for the EPDCCH in a physical resource block (PRB) pair that includes a fixed number of enhanced control channel elements (ECCEs),wherein a minimum level of the aggregation levels set is determined as a first level when the number of the REs for the EPDCCH in the PRB pair is less than a predetermined value;
wherein the minimum level of the aggregation levels set is determined as a second level when the number of the REs for the EPDCCH in the PRB pair is greater than the predetermined value; and
wherein the first level is greater than the second level.

Abstract
The present invention according to one embodiment relates to a method for enabling a terminal to receive control information in a wireless communication system, and the method for receiving the control information comprises the step of attempting to decode a set of enhanced physical downlink control channel (EPDCCH) candidates according to each set level, wherein a minimum value among the values available as the set levels is set according to the amount of available resources for an EPDCCH within a physical resource block (PRB) pair that is attempting to decode.
