Method and apparatus for uplink transmission and reception in a wireless communication system

A User equipment (UE) configured to perform uplink transmission 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, cause the at least one processor to perform operations comprising:
• receiving, from a base station, Sounding Reference Signal (SRS) configuration information related to SRS resources for the UE;
• determining, for each SRS resource set among the plurality of SRS resource sets, information regarding an SRS power control to be applied for all of the plurality of SRS resources within the SRS resource set;
• determining an SRS to be transmitted to the base station, wherein the SRS is included in a first SRS resource set among the plurality of SRS resource sets;
• determining a first transmission power for the SRS, based on the information regarding the SRS power control that is associated with the first SRS resource set that includes the SRS;
• and
• transmitting, to the base station through the transceiver, the SRS using the first transmission power.
