1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a network, a message for deactivating a secondary cell group (SCG) of the UE;
performing a reset of a SCG medium access control (MAC) for a deactivation of the SCG of the UE, based on the message;
determining whether a beam failure detection (BFD) and a radio link monitoring (RLM) for the SCG of the UE while the SCG of the UE is in a deactivated state are configured, based on the message;
in case that the BFD and the RLM for the SCG of the UE are configured, performing the BFD and the RLM for the SCG of the UE while the SCG of the UE is in the deactivated state; and
in case that the BFD and the RLM for the SCG of the UE are not configured, stopping a monitoring of the BFD and stopping an operation of a timer T310 and a timer T312 while the SCG of the UE is in the deactivated state.
