Method for transmitting/receiving uplink channel in wireless communication system, and apparatus therefor

A user equipment (UE) transmitting an uplink channel in a wireless communication system, the UE comprising:

• one or more transceivers;
• one or more processors;
• and
• one or more memories configured to store instructions for operations executed by the one or more processors and be connected to the one or more processors,
• wherein the operations include
• receiving first downlink control information (DCI) based on a first control resource set group;
• wherein a first uplink channel is scheduled based on the first DCI;
• receiving second DCI based on a second control resource set group;
• wherein a second uplink channel is scheduled based on the second DCI;
• and
• transmitting only one of the first uplink channel and the second uplink channel based on overlapping of a resource of the first uplink channel and a resource of the second uplink channel,
• wherein the first uplink channel or the second uplink channel is dropped based on a priority rule, and
• a priority of the priority rule is determined based on contents of information included in each uplink channel.

A device including one or more memories and one or more processors functionally connected to the one or more memories, wherein

• the one or more processors control the device to
• receive first downlink control information (DCI) based on a first control resource set group, wherein a first uplink channel is scheduled based on the first DCI;
• receive a second DCI based on a second control resource set group, wherein a second uplink channel is scheduled based on the second DCI;
• and
• transmit only one of the first uplink channel and the second uplink channel based on overlapping of a resource of the first uplink channel and a resource of the second uplink channel,
• wherein the first uplink channel or the second uplink channel is dropped based on a priority rule, and
• a priority of the priority rule is determined based on contents of information included in each uplink channel.
