1. A method by a terminal, the method comprising:
receiving, from a base station, information for a sounding reference signal (SRS) configuration;
receiving, from the base station, a medium access control (MAC) control element (CE) for activating a semi-persistent (SP) SRS; and
transmitting, to the base station, an SRS on a first cell based on the information for the SRS configuration and the MAC CE for activating the SP SRS,
wherein the MAC CE for activating the SP SRS includes an indicator for indicating whether serving cell information and bandwidth part (BWP) information for a reference signal associated with spatial relationship are present in the MAC CE, and
wherein the BWP information indicates a BWP on which a resource used for spatial relationship derivation for an SRS resource of the SRS is located.
