Abstract: 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.

Abstract: A terminal is disclosed that includes a receiver that receives first downlink control information (DCI) for scheduling initial transmission and second DCI for scheduling retransmission and a processor that controls transmission of a first uplink (UL) shared channel that is scheduled by the first DCI and transmission of a second UL shared channel that is scheduled by the second DCI. The processor controls the transmission of the first UL shared channel and the transmission of the second UL shared channel based on a reference value that is configured for timing for transmitting a UL shared channel based on information provided through higher layer signaling. The processor also controls transmission of the second UL shared channel in response to information included in each of the first DCI and the second DCI that indicates whether the UL shared channel includes initially transmitted data.

Abstract: An apparatus is disclosed that includes a receiver that receives downlink control information that is used for scheduling of a downlink shared channel, via a downlink control channel in a control resource set. The apparatus also includes a processor that determines a starting location in a time domain of the downlink shared channel based on the downlink control information. The apparatus further includes an output device that performs output based on downlink data signal in the downlink shared channel. When the downlink shared channel overlaps with the control resource set, a resource to which the downlink control information is mapped is not available for the downlink shared channel and wherein a field value in the downlink control information indicates an index for designating one of a plurality of starting locations that are provided in advance. In another aspect, a system is also disclosed.
