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

A user equipment (UE) for transmitting uplink control information in a wireless communication system, the UE comprising:

• a transmitter and a receiver for transmitting and receiving a wireless signal, and a processor functionally connected to the RF unit,
• wherein the processor is configured to control to:
• identify a resource region allocated to a first uplink control channel for transmitting first uplink control information and a resource region allocated to a second uplink control channel for transmitting second uplink control information;
• and
• transmitting, to a base station, a specific modulation symbol using a specific uplink resource, based on a transmission of the first uplink control channel overlapping a transmission of the second uplink control channel,
• wherein the specific uplink resource and the specific modulation symbol are configured based on a relative priority between the first uplink control channel and the second uplink control channel,
• wherein a location of the specific uplink resource indicates the first uplink control information, and
• wherein the specific modulation symbol corresponds to the second uplink control information.
