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.

Terminal apparatus and communication method
