Method for performing uplink transmission in wireless communication system and apparatus therefor

A user equipment in a wireless communication system, the user equipment comprising:

• a radio frequency (RF) module including a transceiver;
• at least one processor;
• and
• at least one computer memory operatively coupled to the at least one processor and configured to store instructions performing operations when executed by the at least one processor,
• wherein the operations comprises:
• receiving, from a base station, sounding reference signal (SRS) configuration information that identifies at least one transmission unit of a plurality of transmission units of the user equipment to be used to transmit a SRS for beam management,
• wherein the plurality of transmission units are separated by a distance such that each of the plurality of transmission units are configurable by transmission unit specific SRS configuration parameters, and
• based on the SRS configuration information, transmitting the SRS to the base station through the at least one transmission unit,
• wherein the SRS configuration information also identifies a reception unit of a plurality of reception units of the user equipment to be used for downlink reception,
• wherein the plurality of reception units are respectively associated with the plurality of transmission units, and
• wherein the reception unit is associated with the at least one transmission unit.
