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.
