An operating method of a base station in a wireless communication system includes receiving, from a terminal, information related to a first beam switching time for transmission of an uplink signal, determining a second beam switching time for transmission of the uplink signal, based on configuration information related to the uplink signal and the first beam switching time, transmitting the configuration information related to the uplink signal and the second beam switching time to the terminal, and receiving the uplink signal from the terminal, wherein the uplink signal includes at least one of a sounding reference signal (SRS), a physical uplink shared channel (PUSCH), or a physical uplink control channel (PUCCH).
