Method for transmitting/receiving data in wireless communication system, and device therefor

A method of transmitting and receiving data by a user equipment (UE) in a wireless communication system, the method comprising:

• receiving system information comprising at least one of a master information block (MB) or a system information block (SIB);
• receiving configuration information for configuring a control resource set (CORESET),
• wherein a first CORESET and a second CORESET are configured based on the configuration information,
• wherein the configuration information includes an index of a CORESET group associated with each CORESET;
• receiving first downlink control information (DCI) based on the first CORESET;
• receiving second DCI based on the second CORESET;
• receiving first Physical Downlink Shared channel (PDSCH) scheduled by the first DCI;
• receiving second PDSCH scheduled by the second DCI;
• transmitting first Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) information corresponding to the first PDSCH;
• and
• transmitting second HARQ-ACK information corresponding to the second PDSCH,
• wherein the method further comprising:
• receiving information for determination of a HARQ-ACK codebook,
• wherein the first HARQ-ACK information and the second HARQ-ACK information are based on the HARQ-ACK codebook determined by the information,
• wherein based on an index of a CORESET group associated with the first CORESET being configured differently from an index of a CORESET group associated with the second CORESET, the first HARQ-ACK information and the second HARQ-ACK information are generated separately, and
• wherein the first HARQ-ACK information is associated with the first CORESET and the second HARQ-ACK information is associated with the second CORESET.

A user equipment (UE) configured to transmit and receive data in a wireless communication system, the UE comprising:

• a transceiver;
• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
• receiving system information comprising at least one of a master information block (MIB) or a system information block (SIB);
• receiving configuration information for configuring a control resource set (CORESET),
• wherein a first CORESET and a second CORESET are configured based on the configuration information,
• wherein the configuration information includes an index of a CORESET group associated with each CORESET;
• receiving first downlink control information (DCI) based on the first CORESET;
• receiving second DCI based on the second CORESET;
• receiving first Physical Downlink Shared channel (PDSCH) scheduled by the first DCI;
• receiving second PDSCH scheduled by the second DCI;
• transmitting first Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) information corresponding to the first PDSCH;
• and
• transmitting second HARQ-ACK information corresponding to the second PDSCH,
• wherein the operations further comprising:
• receiving information for determination of a HARQ-ACK codebook,
• wherein the first HARQ-ACK information and the second HARQ-ACK information are based on the HARQ-ACK codebook determined by the information,
• wherein based on an index of a CORESET group associated with the first CORESET being configured differently from an index of a CORESET group associated with the second CORESET, the first HARQ-ACK information and the second HARQ-ACK information are generated separately, and
• wherein the first HARQ-ACK information is associated with the first CORESET and the second HARQ-ACK information is associated with the second CORESET.

One or more non-transitory computer-readable medium storing one or more instructions, the one or more instructions executable by one ore more processors to cause a user equipment (UE) to:

• receive system information comprising at least one of a master information block (MB) or a system information block (SIB);
• receive configuration information for configuring a control resource set (CORESET),
• wherein a first CORESET and a second CORESET are configured based on the configuration information,
• wherein the configuration information includes an index of a CORESET group associated with each CORESET;
• receive first downlink control information (DCI) based on the first CORESET;
• receive second DCI based on the second CORESET;
• receive first Physical Downlink Shared channel (PDSCH) scheduled by the first DCI;
• receive second PDSCH scheduled by the second DCI;
• transmit first Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) information corresponding to the first PDSCH;
• and
• transmit second HARQ-ACK information corresponding to the second PDSCH,
• wherein the one or more instructions to cause the UE further to:
• receive information for determination of a HARQ-ACK codebook,
• wherein the first HARQ-ACK information and the second HARQ-ACK information are based on the HARQ-ACK codebook determined by the information,
• wherein based on an index of a CORESET group associated with the first CORESET being configured differently from an index of a CORESET group associated with the second CORESET, the first HARQ-ACK information and the second HARQ-ACK information are generated separately, and
• wherein the first HARQ-ACK information is associated with the first CORESET and the second HARQ-ACK information is associated with the second CORESET.
