1. A terminal apparatus for communicating with a base station apparatus, comprising:
a receiver configured to receive, from the base station apparatus, a first Physical Downlink Control Channel (PDCCH) including a first Downlink Control Information (DCI) format scheduling a first Physical Downlink Shared Channel (PDSCH), receive, from the base station apparatus, a second PDCCH, after the reception of the first PDCCH, including a second DCI format scheduling a second PDSCH, and receive, from the base station apparatus, a third PDCCH, after the reception of the second PDCCH, including a third DCI format scheduling a third PDSCH; and
a transmitter configured to, in a case that the second DCI format does not indicate one or more PDSCH groups requested to be reported, and does not indicate a New Feedback Indicator (NFI), and the third DCI format indicates more than one PDSCH groups requested to be reported, transmit, to the base station apparatus, a second Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK) bit for a transport block in the second PDSCH in a first Physical Uplink Control Channel (PUCCH), and transmit, to the base station apparatus, a first HARQ-ACK bit for a transport block in the first PDSCH and a third HARQ-ACK bit for a transport block in the third PDSCH in a second PUCCH which is transmitted after the transmission of the first PUCCH.
