Abstract

Provided is an apparatus and method for transmitting downlink control information in a wireless communication system. According to the present disclosure, the method comprises the steps of: configuring a hybrid field including any or both of main control information and sub control information; configuring downlink control information including the hybrid field; transmitting the downlink control information to a terminal; and receiving uplink information from the terminal on the basis of the downlink control information. According to the present invention, new control information can be added while maintaining the existing DCI format, thereby providing compatibility with existing systems without increasing the complexity of blind decoding.
