Disclosed is a method for a base station to transmit a downlink control channel in a wireless communication system. Specifically, the method comprises the steps of: separating each resource block, of which there are at least one, into a preconfigured number of subsets; structuring basic resource allocation units for an downlink control channel as one of the subsets comprised in one or more resource blocks; configuring the basic resource allocation units, the number of which correspond to the aggregation level of the downlink control channel, as transmission resources; and using the transmission resource to transmit the downlink control channel to a terminal.
