1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, a first radio resource control (RRC) message indicating that a secondary cell group (SCG) is in deactivated state; and
deactivating the SCG and resetting a medium access control (MAC) entity for the SCG based on the first RRC message,
wherein the resetting of the MAC entity comprises stopping at least one timer in the MAC entity except a time alignment timer.
