    摘要： Disclosed in one embodiment is a downlink control channel decoding method of a wireless communication system, comprising the steps of: receiving setting information on a first resource and a second resource; blind-decoding reception signals on PDCCH resource candidates within the first resource determined by the setting information, so as to search for a PDCCH of the first resource; and blind-decoding reception signals on PDCCH resource candidates within the second resource determined by the setting information, and by blind-decoding, among the resource candidates, the remaining one or more resource candidates excluding one or more resource candidates, which include a resource area overlapping with the PDCCH having been searched for, so as to search for a PDCCH of the second resource. Therefore, since the number of PDCCH resource candidates required for blind-decoding is adjusted on the basis of an overlapping resource area, power consumption of a terminal can be reduced.
