Disclosed is a method for a base station to transmit a downlink control channel to a terminal in a time division duplex (TDD)-based wireless communication system. Specifically, the method comprises the steps of: determining the number of basic resource allocation units for each resource block pair for a downlink control channel on the basis of the type of a sub-frame during which the downlink control channel is transmitted; mapping, by basic resource allocation unit, control information for the terminal to a transmission resource; and transmitting, to the terminal, the downlink control channel comprising the control information, wherein, if the type of the sub-frame, during which the downlink control channel is transmitted, is the type in which a downlink transmission interval and a uplink transmission interval coexist, then the number of basic resource allocation unit for each resource block pair is determined on the basis of the length of the downlink transmission interval. |
