Abstract:
A terminal apparatus receives a higher layer parameter and a PDSCH, and generates a HARQ-ACK codebook and transmits the generated HARQ-ACK codebook on a PUCCH. In a case that a first parameter is configured, a first HARQ-ACK codebook and a second HARQ-ACK codebook are generated, the first HARQ-ACK codebook is used to transmit a HARQ-ACK bit corresponding to a PDSCH A, and the second HARQ-ACK codebook is used to transmit a HARQ-ACK bit corresponding to a PDSCH B. In a case that the first parameter is not configured, the first HARQ-ACK codebook is generated, and the first HARQ-ACK codebook is used to transmit the HARQ-ACK bit corresponding to the PDSCH B.
