1. A method performed by a base station, the method comprising:
transmitting first information indicating sounding reference signal (SRS) spatial relation information for a SRS resource, wherein the SRS spatial relation information comprises:
a plurality of SRS spatial relation information identifiers; and
a SRS spatial relation information reference signal corresponding to each SRS spatial relation information identifier of the plurality of SRS spatial relation information identifiers;
transmitting second information indicating an update to the SRS spatial relation information of the SRS resource, wherein the second information comprises:
a serving cell identifier;
a bandwidth part identifier;
one or more SRS resource identifiers, one or more SRS resource set identifiers, or a combination thereof; and
one or more SRS spatial relation information identifiers of the plurality of SRS spatial relation information identifiers, wherein each of the one or more SRS resource identifiers corresponds to each of the one or more SRS spatial relation information identifiers; and
transmitting third information indicating one or more simultaneous spatial relation cell lists for updating the SRS spatial relation information using radio resource control (RRC) signaling.
