1. A method by a terminal, the method comprising:
transmitting, by the terminal to a base station, a UECapabilityInformation, wherein the UECapabilityInformation comprises first capability information related to provision of Multi-Universal Subscriber Identity Module (MUSIM) assistance data, and wherein the first capability information being comprised in the non-critical extension of UE-NR-Capability indicates that provision of MUSIM assistance data is supported in Frequency Division Multiplexing (FDD) and in Time Division Multiplexing (TDD) and in Frequency Region (FR) 1 and in FR2;
receiving, by the terminal from the base station, a RRCReconfiguration, wherein the RRCReconfiguration comprises configuration information related to terminal state transition, wherein the configuration information related to terminal state transition comprises information for a first timer, and wherein the first timer is related to terminal state transition;
transmitting, by the terminal to the base station, a UEAssistanceInformation, wherein the UEAssistanceInformation comprises information related to a state requested by the terminal, and wherein the state requested by the terminal is a first state;
starting, by the terminal, the first timer after initiating transmission of the UEAssistanceInformation; and
performing, by the terminal, state transition to a second state when the first timer expires,
wherein the terminal restarts the first timer when a first handover is completed,
wherein the first handover is performed from a first new radio (NR) cell to a second NR cell,
wherein the terminal does not restart the first timer when a second handover is completed, and
wherein the second handover is performed from the first NR cell to an Evolved Universal Terrestrial Radio Access (EUTRA) cell.
