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

A base station (BS) for transmitting and receiving data in a wireless communication system, the BS comprising:

• one or more transceivers;
• one or more processors;
• and
• one or more memories storing instructions for operations executed by the one or more processors and connected to the one or more processors,
• wherein the operations comprise:
• transmitting first control information based on a first control resource set (CORESET) of a first CORESET group;
• transmitting second control information based on a second CORESET of a second CORESET group;
• transmitting at least one of (i) a first data scheduled based on the first control information or (ii) a second data scheduled based on the second control information;
• and
• receiving, first feedback information corresponded to the first data and second feedback information corresponded to the second data,
• wherein an index of the first CORESET group and an index of the second CORESET group have different values
• wherein each of the first control information and the second control information includes a Downlink Assignment Index (DAI) field, and
• wherein a value of the DAI field is configured based on the index of the first COREST group and the index of the second CORESET group.

One or more non-transitory computer-readable media storing one or more instructions, when executed by one or more processors, configure the one or more processors to perform operations,

• wherein the operations comprise:
• transmitting first control information based on a first control resource set (CORESET) of a first CORESET group;
• transmitting second control information based on a second CORESET of a second CORESET group;
• transmitting at least one of (i) a first data scheduled based on the first control information or (ii) a second data scheduled based on the second control information;
• and
• receiving, first feedback information corresponded to the first data and second feedback information corresponded to the second data,
• wherein an index of the first CORESET group and an index of the second CORESET group have different values,
• wherein each of the first control information and the second control information includes a Downlink Assignment Index (DAI) field, and
• wherein a value of the DAI field is configured based on the index of the first COREST group and the index of the second CORESET group.
