Abstract: A terminal includes: a reception unit configured to receive DCI (Downlink Control Information) including an index indicating a row in a TDRA (Time Domain Resource Allocation) table and an upper layer parameter from a base station; a control unit configured to determine positions of one or a plurality of PUSCHs (Physical Uplink Shared Channel) scheduled in a time domain, based on the index and the upper layer parameter; and a transmission unit configured to transmit the one or the plurality of PUSCHs to the base station. In a case where the upper layer parameter is configured to be enabled and the index indicates scheduling of a single PUSCH in the TDRA, the control unit determines that the single PUSCH is to be repeatedly transmitted.

Abstract: A terminal includes: a reception unit configured to receive data according to SPS (Semi persistent scheduling) from a base station; a control unit configured to determine HARQ-ACK (Hybrid automatic repeat request Acknowledgement) feedback information corresponding to the data, wherein transmission of the HARQ-ACK feedback information is required to be postponed until a valid uplink resource is found, configure a HARQ-ACK codebook related to the feedback information, and determine bits of the feedback information by applying the codebook; and a transmission unit configured to transmit the feedback information to the base station. The control unit configures the codebook based on priorities configured to the bits.
