2. A radio communication method for terminal comprising:
receiving a first physical downlink shared channel (PDSCH) scheduled by downlink control information (DCI);
determining, when a dynamic hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook is configured, a codebook for a first physical uplink control channel (PUCCH) transmitted with repetitions per slot, based on at least one of a total downlink assignment index (T-DAI), a counter downlink assignment index (C-DAI), and information indicating a timing from reception of the first PDSCH to transmission of HARQ-ACK for the first PDSCH, the T-DAI and the C-DAI being included in the DCI; and
transmitting, on the first PUCCH, HARQ-ACK based on the codebook;
when a period for repetitions of first PUCCH transmission collides with a period for transmission of an uplink control information (UCI) type which is different from the HARQ-ACK, not performing to transmit the UCI type and controlling to transmit the first PUCCH; and
when the period for repetitions of the first PUCCH transmission collides with a period for a second PUCCH transmission with HARQ-ACK for a second PDSCH, which is different from the first PDSCH, not performing to transmit the second PUCCH starting at a later slot, and controlling to transmit the first PUCCH starting at an earlier slot.
