Abstract
A method of transmitting a downlink control signal is disclosed, by which localized allocation and distributed allocation are efficiently used in transmitting a downlink control signal. The present invention includes multiplexing the downlink control signal in a manner of if there exists downlink data transmission to a prescribed UE, applying localized allocation to a transmission of the downlink control signal including the scheduling information on the uplink data transmission of the UE and applying distributed allocation to another transmission of the downlink control signal and transmitting the multiplexed downlink control signal.
