Abstract

A communication method used for a terminal device is provided. The communication method comprises triggering transmission of a first hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook; and when transmission of a second HARQ-ACK codebook is triggered before the first HARQ-ACK codebook has been transmitted, canceling the transmission of the first HARQ-ACK codebook; and transmitting the second HARQ-ACK codebook.

Claims (24)

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.

2. The terminal device according to claim 1 , wherein the one or more computer-executable instructions, when executed by the at least one processor, further cause the terminal device to:

when a first HARQ process set comprising one or more HARQ processes corresponding to the at least one HARQ-ACK included in the first HARQ-ACK codebook is included in a second HARQ process set comprising one or more HARQ processes corresponding to the at least one HARQ-ACK included in the second HARQ-ACK codebook, cancel the transmission of the first HARQ-ACK codebook.

3. The terminal device according to claim 2 , wherein the one or more computer-executable instructions, when executed by the at least one processor, further cause the terminal device to:

when the first HARQ process set is not included in the second HARQ process set, forgo canceling the transmission of the first HARQ-ACK codebook.

4. A communication method used for a terminal device, the communication method comprising:

triggering 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:

canceling the transmission of the first HARQ-ACK codebook, and

transmitting 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.

5. The communication method according to claim 4 , further comprising:

when a first HARQ process set comprising one or more HARQ processes corresponding to the at least one HARQ-ACK included in the first HARQ-ACK codebook is included in a second HARQ process set comprising one or more HARQ processes corresponding to the at least one HARQ-ACK included in the second HARQ-ACK codebook, canceling the transmission of the first HARQ-ACK codebook.

6. The communication method according to claim 5 , further comprising:

when the first HARQ process set is not included in the second HARQ process set, forgoing canceling the transmission of the first HARQ-ACK codebook.
