Patent attributes
The present invention is designed so that uplink control information such as delivery acknowledgment signals can be transmitted properly, even when UL/DL configurations are changed, in a communication system that is configured to use listening. According to one aspect of the present invention, a user terminal has a receiving section that receives downlink control information and downlink data, a transmission section that transmits a delivery acknowledgment signal in response to the downlink data, and a control section that controls transmission of the delivery acknowledgment signal based on a result of UL listening which is executed before transmission of the delivery acknowledgment signal, and based on information that is contained in the downlink control information and/or timing that is configured in advance on a per DL burst basis.
