1. A method of controlling transmission power of a sounding reference signal (SRS) by a user equipment (UE) in a wireless communication system, the method comprising:
receiving a synchronization signal/physical broadcast channel (SS/PBCH) block including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH);
performing access to a serving cell based on system information included in the PBCH of the SS/PBCH block;
receiving a reference signal (RS) resource for obtaining path loss to be used for the transmission power of the SRS;
determining measurement regarding the path loss based on the RS resource; and
controlling the transmission power of the SRS based on the determination of the measurement,
wherein the RS resource is related to a neighbor cell,
wherein based on success of the measurement for the RS resource, a measurement value of the path loss is used to control the transmission power, and
wherein based on failure of the measurement for the RS resource, information related to a power configuration obtained from the serving cell is used to control the transmission power.
