  • Publication number: 20230072973
    Abstract: A terminal apparatus includes a receiver configured to receive a PDCCH including DCI triggering a Type-3 HARQ-ACK codebook, and a transmitter configured to transmit a PUCCH including the Type-3 HARQ-ACK codebook triggered. A slot in which the PUCCH is transmitted is provided based on K1 obtained based on a PDSCH-to-HARQ_feedback timing indicator field included in the DCI. In a case that the DCI schedules a PDSCH, the PUCCH is transmitted the K1 slots after a slot in which the PDSCH is received. In a case that the DCI does not schedule a PDSCH, the PDCCH is transmitted in a slot after slots corresponding to the K1 from a slot in which the PDCCH is received.

  • Publication number: 20230067648
    Abstract: A terminal apparatus includes a reception circuitry configured to receive a DCI format used for scheduling of a PUSCH, and a transmission circuitry configured to transmit the PUSCH in multiple slots. A size of a transport block is given based on a target coding rate indicated by the DCI format. The target coding rate is 1 or greater. An effective coding rate of the PUSCH is 1 or less. The effective coding rate is a value obtained by dividing the size of the transport block by a product of a modulation order of the PUSCH and the number of resource elements of the PUSCH.
