Method and device for transmitting and receiving signal in wireless communication system

A device for wireless communication, the device comprising:

• a processor;
• and
• a memory configured to store instructions that, when executed by the processor, perform operations comprising:
• obtaining information regarding a plurality of time domain resource allocation (TDRA) entries each having one or more parameter sets, wherein each of the one or more parameter sets includes a K0 value and a start and length indicator value (SLIV) for a physical downlink shared channel (PDSCH), and the K0 value denotes downlink control information (DCI)-to-PDSCH slot offset;
• receiving a single DCI for scheduling a plurality of PDSCHs;
• receiving the plurality of PDSCHs in PDSCH occasions related to the single DCI;
• determining a hybrid automatic repeat request (HARQ)-acknowledgment (ACK) for a set of PDSCH occasions including the PDSCH occasions related to the single DCI, based on Type-1 HARQ-ACK codebook;
• and
• transmitting the HARQ-ACK in a slot associated with a K1 value determined based on the single DCI, wherein the K1 value denotes PDSCH-to-HARQ feedback timing, and the K1 value is determined from among K1 values configured in the device through higher layer signaling,
• wherein, for a TDRA entry having multiple parameter sets including a first parameter set and at least one second parameter set, the device determines the set of PDSCH occasions to include:
• i) first PDSCH occasions that can be scheduled in first slots, wherein the first slots are determined based on the K1 values configured through the higher layer signaling and the first parameter set including a first K0 value which is a largest K0 value in the TDRA entry, and
• ii) second PDSCH occasions that can be scheduled in at least one second slot, wherein the at least one second slot is based on the at least one second parameter set including at least one second K0 value smaller than the largest K0 value.

A method of transmitting a signal by a base station (BS) in a wireless communication system, the method comprising:

• transmitting information regarding a plurality of time domain resource allocation (TDRA) entries each having one or more parameter sets, wherein each of the one or more parameter sets includes a K0 value and a start and length indicator value (SLIV) for a physical downlink shared channel (PDSCH), and the K0 value denotes downlink control information (DCI)-to-PDSCH slot offset;
• transmitting a single DCI for scheduling a plurality of PDSCHs;
• transmitting the plurality of PDSCHs in PDSCH occasions related to the single DCI;
• and
• receiving, based on Type-1 HARQ-ACK codebook, a hybrid automatic repeat request (HARQ)-acknowledgment (ACK) in a slot associated with a K1 value indicated by the single DCI, wherein the K1 value denotes PDSCH-to-HARQ feedback timing, and the K1 value is determined from among K1 values configured in a user equipment (UE) by the BS through higher layer signaling,
• wherein the HARQ-ACK is for a set of PDSCH occasions including the PDSCH occasions related to the single DCI, based on the Type-1 HARQ-ACK codebook,
• wherein, for a TDRA entry having multiple parameter sets including a first parameter set and at least one second parameter set, the set of PDSCH occasions include:
• i) first PDSCH occasions that can be scheduled in first slots, wherein the first slots are determined based on the K1 values configured through the higher layer signaling and the first parameter set including a first K0 value which is a largest K0 value in the TDRA entry, and
• ii) second PDSCH occasions that can be scheduled in at least one second slot, wherein the at least one second slot is based on the at least one second parameter set including at least one second K0 value smaller than the largest K0 value.
