    Abstract: The present disclosure is related to adjusting a blind decoding of a downlink control channel in a base station. A method of adjusting a blind decoding of a downlink control channel may include creating an enhanced physical downlink control channel (EPDCCH) using the number of EPDCCH candidates per aggregation level (AL) in each of one or more EPDCCH sets for user equipment; and transmitting the created EPDCCH to the user equipment. Herein, the number of EPDCCH candidates is determined based on at least one of (i) a resource size associated with configuration of each EPDCCH set and (ii) the total number of EPDCCH sets.
