Method and device for transmitting or receiving signal in wireless communication system
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.
1. A method of transmitting a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) report 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) requesting a specific type codebook-based HARQ-ACK report for one-shot-based transmission of acknowledgement/negative acknowledgements (ACK/NACKs) for all HARQ processes of one or more serving cells configured for the UE; and
transmitting the HARQ-ACK report based on the DCI,
wherein, based on a PDSCH being not scheduled by the DCI, a location of a time resource for the specific type codebook-based HARQ-ACK report is determined based on a location of a time resource for reception of the PDCCH.
2. The method of claim 1 ,
wherein the location of the time resource for reception of the PDCCH is a symbol in which the reception of the PDCCH ends, and the location of the time resource for the specific type codebook-based HARQ-ACK report is a symbol in which transmission of the specific type codebook-based HARQ-ACK report starts.
3. The method of claim 1 ,
wherein, an interval between the location of the time resource for reception of the PDCCH and the location of the time resource for the specific type codebook-based HARQ-ACK report is determined according to subcarrier spacing (SCS).
4. The method of claim 1 ,
wherein the location of the time resource for the specific type codebook-based HARQ-ACK report is determined according to a HARQ-ACK timing related to an semi-persistent scheduling (SPS) PDSCH release indication.
5. The method of claim 1 ,
wherein the specific type codebook is a Type-3 codebook,
the UE receives a Type-3 codebook-based HARQ-ACK configuration through higher layer signaling.
6. The method of claim 5 ,
wherein, the UE determines whether a codeblock group (CBG)-based ACK/NACK for a serving cell in which codeblock group (CBG)-based scheduling is configured should be reported and whether a new data indicator (NDI) should be reported, based on the Type-3 codebook-based HARQ-ACK configuration.
7. The method of claim 1 ,
wherein an ACK/NACK bit of a lower indexed serving cell is mapped to a lower index bit in the specific type codebook-based HARQ-ACK report,
among ACK/NACK bits of the same index serving cell, an A/N bit of a lower index HARQ process is mapped to a lower index bit in the specific type codebook-based HARQ-ACK report,
among A/N bits of the same index HARQ process, an ACK/NACK bit of a lower index transport block (TB) is mapped to a lower index bit in the specific type codebook-based HARQ-ACK report.
8. The method of claim 7 ,
wherein among ACK/NACK bits of a plurality of codeblock groups (CBGs) included in a corresponding TB, an ACK/NACK bit of a lower index CBG is mapped to a lower index bit in the specific type codebook-based HARQ-ACK report.
9. A user equipment (UE) for wireless communication, the UE comprising:
a transceiver; and
a processor for receiving, through a physical downlink control channel (PDCCH), downlink control information (DCI) requesting a specific type codebook-based HARQ-ACK report for one-shot-based transmission of acknowledgement/negative acknowledgements (ACK/NACKs) for all HARQ processes of one or more serving cells configured for the UE and transmitting a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) report based on the DCI, by controlling the transceiver,
wherein, based on a PDSCH being not scheduled by the DCI, a location of a time resource for the specific type codebook-based HARQ-ACK report is determined based on a location of a time resource for reception of the PDCCH.
10. A method of receiving a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) report by a base station in a wireless communication system, the method comprising:
transmitting, to a user equipment (UE) through a physical downlink control channel (PDCCH), downlink control information (DCI) requesting a specific type codebook-based HARQ-ACK report for one-shot-based transmission of acknowledgement/negative acknowledgements (ACK/NACKs) for all HARQ processes of one or more serving cells configured for the UE; and
receiving, from the UE, the HARQ-ACK report based on the DCI,
wherein, based on a PDSCH being not scheduled by the DCI, a location of a time resource for the specific type codebook-based HARQ-ACK report is determined based on a location of a time resource for reception of the PDCCH.
