Abstract
The present invention is designed to prevent communication performance from dropping in long TTI when preemption of long TTI by short TTI occurs. According to one aspect of the present invention, a user terminal has a receiving section that receives downlink (DL) data based on downlink control information (DCI) in a first transmission time interval (TTI), a transmission section that transmits delivery acknowledgement information in response to the DL data, and a control section that controls timing of transmitting the delivery acknowledgement information when indication information regarding preemption of the first TTI by a second TTI shorter than the first TTI is received in the receiving section.
