Abstract
A UE according to an embodiment of the present disclosure receives DCI of a DL grant format through a PDCCH and transmits a HARQ-ACK report, in a state in which the DCI of the DL grant format indicates a specific type codebook-based HARQ-ACK report for one-shot-based transmission of ACK/NACKs for all HARQ processes of serving cells, the UE may determine a time resource for the specific type codebook-based HARQ-ACK report based on whether a PDSCH is scheduled by the DCI.
Claims15
A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, through a physical downlink control channel (PDCCH), downlink control information (DCI) including a one-shot hybrid automatic repeat request (HARQ)-acknowledgement (ACK) request field for requesting the UE to report acknowledgement/negative acknowledgement (ACK/NACK) for all HARQ processes of one or more serving cells configured for the UE;
- and
- transmitting HARQ-ACK information in a Type-3 HARQ-ACK codebook,
- wherein, based on the DCI not scheduling a PDSCH, the HARQ-ACK information is transmitted after N (N is a natural number) symbols from the last symbol of the PDCCH providing the DCI.
A user equipment (UE) configured to operate in a wireless communication system, the UE comprising:
- at least one transceiver for transmitting and receiving a wireless signal;
- at least one processor for controlling the at least one transceiver;
- and
- at least one memory connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
- receiving, through a physical downlink control channel (PDCCH), downlink control information (DCI) including a one-shot hybrid automatic repeat request (HARQ)-acknowledgement (ACK) request field for requesting the UE to report acknowledgement/negative acknowledgement (ACK/NACK) for all HARQ processes of one or more serving cells configured for the UE;
- and
- transmitting HARQ-ACK information in a Type-3 HARQ-ACK codebook,
- wherein, based on the DCI not scheduling a PDSCH, the HARQ-ACK information is transmitted after N (N is a natural number) symbols from the last symbol of the PDCCH providing the DCI.
A base station configured to operate in a wireless communication system, the base station comprising:
- at least one transceiver for transmitting and receiving a wireless signal;
- at least one processor for controlling the at least one transceiver;
- and
- at least one memory connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
- transmitting, through a physical downlink control channel (PDCCH), downlink control information (DCI) including a one-shot hybrid automatic repeat request (HARQ)-acknowledgement (ACK) request field for requesting a user equipment (UE) to report acknowledgement/negative acknowledgement (ACK/NACK) for all HARQ processes of one or more serving cells configured for the UE;
- and
- receiving HARQ-ACK information in a Type-3 HARQ-ACK codebook,
- wherein, based on the DCI not scheduling a PDSCH, the HARQ-ACK information is received after N (N is a natural number) symbols from the last symbol of the PDCCH providing the DCI.
