1. A terminal device comprising:
at least one processor; and
at least one non-transitory computer-readable medium storing one or more computer-executable instructions that, when executed by the at least one processor, cause the terminal device to:
trigger a transmission of a first hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook; and
when a transmission of a second HARQ-ACK codebook is triggered before the first HARQ-ACK codebook has been transmitted:
cancel the transmission of the first HARQ-ACK codebook, and
transmit the second HARQ-ACK codebook, wherein:
the first HARQ-ACK codebook defines a relationship between a slot in which the first HARQ-ACK codebook is transmitted/received and a physical downlink shared channel (PDSCH) slot corresponding to a HARQ-ACK among at least one HARQ-ACK included in the first HARQ-ACK codebook, and
the second HARQ-ACK codebook defines a HARQ process of a PDSCH corresponding to a HARQ-ACK among at least one HARQ-ACK included in the second HARQ-ACK codebook.
