Abstract:
According to one aspect of the present disclosure, a user terminal includes a control section that determines, when an uplink control channel (PUCCH) repetition and a dynamic hybrid automatic repeat reQuest acknowledgement (HARQ-ACK) codebook are configured, a codebook for PUCCH transmission per slot based on at least one of a total downlink assignment index (T-DAI), a counter downlink assignment index (C-DAI), a timing from reception of a physical downlink shared channel (PDSCH) to transmission of the HARQ-ACK corresponding to the PDSCH and repetition factor, and a transmitting section that transmits HARQ-ACK based on the codebook by applying PUCCH repetition to the HARQ-ACK. According to one aspect of the present disclosure, it is possible to appropriately transmit the UCI even when the PUCCH repetition is used.
