1. A terminal apparatus comprising:
a transmitter configured to transmit a HARQ-ACK codebook on a PUCCH in a slot; and
a receiver configured to receive multiple DCI formats on a set of PDCCH monitoring occasions corresponding to the slot, wherein
a resource for the PUCCH is determined by a PUCCH resource indicator field included in one of the multiple DCI formats that is received last,
the HARQ-ACK codebook is a first HARQ-ACK codebook type in a case that at least one of the multiple DCI formats is set to trigger the first HARQ-ACK codebook type, and
the HARQ-ACK codebook is a second HARQ-ACK codebook different from the first HARQ-ACK codebook in a case that none of the multiple DCI formats are set to trigger the first HARQ-ACK codebook type.
