Abstract: Proposes are: a method for performing a radio resource control (RRC) connection re-establishment procedure by a user equipment (UE) in a wireless communication system, and a device supporting the same. The method includes: entering an RRC connected state; receiving an RRC connection re-establishment condition; determining whether the RRC connection re-establishment condition is satisfied based on a measurement result; and performing an RRC connection re-establishment procedure when the RRC connection re-establishment condition is satisfied, wherein the UE is a UE not supporting a handover in the RRC connected state.

Abstract: A method handling a link failure by a user equipment (UE) in a wireless communication system is disclosed. The method includes steps of suspending at least one data radio bearer (DRB) upon detecting an occurrence of the link failure; transmitting, to a specific cell, a radio resource control message indicating the occurrence of the link failure; receiving a response message as a response of the radio resource control message from the specific cell; and resuming the at least one suspended DRB.

Abstract: Provided are a method for performing a handover by a user equipment (UE) in a wireless communication system, and an apparatus supporting the same. The method may include: receiving information on candidate target cells for the handover and a handover condition, from a base station; initiating a handover to a first target cell among the candidate target cells, based on the handover condition; before detecting a failure of the handover to the first target cell, when channel quality of a second target cell among the candidate target cells is higher than channel quality of the first target cell, stopping the handover to the first target cell; and performing a handover to the second target cell.

Abstract: Provided are a method for receiving an on-demand system information (OSI) block by a terminal in a wireless communication system and an apparatus for supporting the same. The method may comprise the steps of: receiving, from a network, an on-demand system information (OSI) configuration including information on mapping between the OSI block and information on a system information request (SIR) preamble; determining an OSI block of interest; selecting an SIR preamble corresponding to the OSI block of interest on the basis of the OSI configuration; transmitting the selected SIR preamble to a serving cell so as to request the determined OSI block of interest; and receiving the requested OSI block of interest.

Abstract: A method and apparatus for configuring measurements in a wireless communication system is provided. A user equipment (UE) receives a reference signal (RS) indicator from a network, and evaluates whether a measurement report triggering event is satisfied by only using a measurement result based on a RS indicated by the RS indicator. The RS indicator may indicate which RS is used for reporting the measurement result. The RS indicator may indicate a cell-specific reference signal (CRS) or a discovery reference signal (DRS).
