Abstract
The present disclosure relates to a wireless communication system, and specifically, a method and an apparatus therefor, the method comprising: receiving at least one PDSCH, wherein each PDSCH belongs to one of two PDSCH groups; receiving DCI for scheduling a PUSCH, wherein the DCI includes a single DAI related to only one of the two PDSCH groups; and transmitting the control information including an A/N codebook for at least one of the two PDSCH groups.
Claims15
A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving first downlink control information (DCI), wherein the first DCI includes a single physical downlink shared channel (PDSCH) group index value and a value of a number of requested PDSCH groups, and wherein a first PDSCH group index of a first PDSCH group of two PDSCH groups is set to the single PDSCH group index value and a second PDSCH group index of a second PDSCH group of the two PDSCH groups that is different from the first PDSCH group index is determined based on the single PDSCH group index value;
- receiving PDSCHs, wherein each of the PDSCHs belongs to one of the two PDSCH groups;
- receiving second DCI for scheduling a physical uplink shared channel (PUSCH), wherein the second DCI includes a single downlink assignment index (DAI);
- and
- transmitting hybrid automatic repeat request (HARQ)-acknowledgement (ACK) information,
- wherein based on i) the HARQ-ACK information including ACK/negative ACK (NACK) information for both the first PDSCH group and the second PDSCH group and ii) the first PDSCH group index is 0, the single DAI is used to generate a HARQ-ACK codebook for the first PDSCH group.

A user equipment (UE) operating in a wireless communication system, the UE comprising:
- at least one transceiver for transmitting and receiving a wireless signal;
- and
- at least one processor for controlling the at least one transceiver,
- wherein the at least one processor configured to:
- receive first downlink control information (DCI), wherein the first DCI includes a single physical downlink shared channel (PDSCH) group index value and a value of a number of requested PDSCH groups, and wherein a first PDSCH group index of a first PDSCH group of two PDSCH groups is set to the single PDSCH group index value and a second PDSCH group index of a second PDSCH group of the two PDSCH groups that is different from the first PDSCH group index is determined based on the single PDSCH group index value;
- receiving PDSCHs, wherein each of the PDSCHs belongs to one of the two PDSCH groups;
- receiving second DCI for scheduling a physical uplink shared channel (PUSCH), wherein the second DCI includes a single downlink assignment index (DAI);
- and
- transmitting hybrid automatic repeat request (HARQ)-acknowledgement (ACK) information,
- wherein based on i) the HARQ-ACK information including ACK/negative ACK (NACK) information for both the first PDSCH group and the second PDSCH group and ii) the first PDSCH group index is 0, the single DAI is used to generate a HARQ-ACK codebook for the first PDSCH group.
