Abstract: A method for restarting a prohibit timer in a wireless communication system, the method performed by a user equipment (UE) includes starting the prohibit timer related to a transmission of power preference information; receiving, from a network, a handover message including a timer value; performing a handover procedure based on the received handover message; restarting the prohibit timer based on applying the received timer value included in the handover message; and stopping the prohibit timer based on whether the UE initiates radio resource control (RRC) re-establishment procedure while the prohibit timer is running. Further, upon initiating the RRC re-establishment procedure, the UE disables the transmission of the power preference information and stops the prohibit timer.

Abstract: A method is performed by a user equipment (UE) in a wireless communication system, wherein the UE is capable of a traffic steering between a first network system and a second network system. The method includes receiving at least one identifier (ID) related to the second network system from the first network system; receiving assistance information from the first network system; evaluating the conditions for the traffic steering only on a primary cell (PCell) among a plurality of serving cells based on the received assistance information; and performing the traffic steering from the first network system to the second network system when the conditions for the traffic steering are met on the PCell.

Abstract: Provided are a cell selection/re-selection method for an inter-frequency sidelink operation executed by a terminal in a wireless communication system, and a terminal using the method. The method is characterized by determining whether cell selection/re-selection parameters which can be applied to a non-serving frequency to execute a sidelink operation have been configured and received; and when the cell selection/re-selection parameters have been configured and received, performing an evaluation for the cell selection/reselection or ranking of a cell in the non-serving frequency by using the cell selection/re-selection parameters.
