1. A method comprising:
receiving, by a terminal, from a base station, configuration information related to a plurality of reference signals for estimating pathloss;
receiving, by the terminal, from the base station, control information for updating a first reference signal for a specific target uplink channel or signal to a second reference signal, wherein the first reference signal and the second reference signal belong to the plurality of reference signals, the first reference signal is referenced by multiple uplink channels or signals, and the multiple uplink channels or signals include the specific target uplink channel or signal;
based on the second reference signal being not an activated reference signal for the terminal, updating the first reference signal for the multiple uplink channels or signals to the second reference signal; and
transmitting, to the base station, an uplink the multiple uplink channels or signals based on the second reference signal.
