Abstract: In a control region of a first subframe, first downlink control information (DCI) for a second subframe may be transmitted to a user equipment. The user equipment monitors DCI in a control region of the second subframe. The user equipment operates on the basis of the second DCI if the second DCI for the second subframe is detected in the control region of the second subframe, and can receive downlink data or transmit uplink data in a data area of the second subframe on the basis of the first DCI if the second DCI is not detected.
