1. A method of transmitting a sounding reference signal (SRS) by a user equipment (UE) in a wireless communication system, the method comprising:
receiving configuration information related to a plurality of transmission configuration indication (TCI) states;
determining a spatial filter for an SRS resource of the SRS based on a specific TCI state among the plurality of TCI states;
determining an SRS transmission power for an SRS resource set including the SRS resource with a higher layer parameter of usage which is set to beam management based on the specific TCI state; and
transmitting the SRS through the SRS resource based on the spatial filter and the SRS transmission power,
wherein the specific TCI state is at least one of an uplink TCI state or a joint TCI state.
