1. A method of transmitting an uplink signal in a wireless communication, the method performed by a terminal, the method comprising:
receiving, from a base station, first configuration information related to a sounding reference signal (SRS) and second configuration information related to an uplink demodulation reference signal (DMRS);
transmitting, to the base station, the uplink DMRS for uplink transmission; and
transmitting, to the base station, the SRS in one or more SRS resources in an SRS resource set configured by the first configuration information,
wherein based on both i) the SRS and the uplink DMRS being configured to be located in a specific range in a time domain and ii) the SRS and the uplink DMRS being configured to fully or partially overlap in a frequency domain, time domain bundling between the SRS and the uplink DMRS is determined,
wherein even though a spatial domain transmission filter for transmitting the uplink DMRS is configured by the second configuration information, based on the time domain bundling between the SRS and the uplink DMRS being determined, the uplink DMRS is transmitted with a same spatial domain transmission filter as the SRS, and
wherein one of a first pathloss reference signal configured for the SRS or a second pathloss reference signal configured for the uplink transmission is used to determine transmission power of both the SRS and the uplink transmission.
