Abstract
A method, performed by a user equipment (UE), for controlling activation of a cell group includes: receiving, from a base station, a radio resource control (RRC) message including configuration information indicating a number of temporary reference signals; receiving, from the base station, a medium access control (MAC) control element (CE) indicating to activate a secondary cell (SCell); receiving, from the base station, a temporary reference signal; based on the MAC CE and the RRC message, measuring the temporary reference signal; and transmitting, to the base station, a measurement result regarding the temporary reference signal.
