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: Provided are a method for a user equipment (UE) to request system information in a wireless communication system and a device supporting the same. The method may include: transmitting a random access preamble for requesting system information to a base station (BS); receiving, from the BS, a random access response including only a random access preamble identifier (RAPID) corresponding to the transmitted random access preamble; and considering that a random access procedure is completed.

Abstract: There is provided a method for transmitting an uplink message, the method performed by a user equipment (UE). The method may comprise: receiving, by the UE, a request about a visited cell history; transmitting, by the UE, in response to the request, the visited cell history. Here, the cell visited history may include an identifier of a visited cell, and time information corresponding to the visited cell.

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).

Abstract: Provided is a method for a terminal performing a random access procedure in a wireless communication system. The method comprises the steps of: transmitting, to a base station, a first random access preamble corresponding to a system information block-of-interest; receiving, from the base station, a random access response including a random access preamble identifier, wherein the random access preamble identifier indicates a second random access preamble; and determining that the random access response is valid for the terminal if the second random access preamble is included in the same preamble group as the first random access preamble.

Abstract: A method and an apparatus for reporting an ID of specific BWP among the multiple BWPs in a wireless communication system is provided. The method, by a UE, may include configuring multiple bandwidth parts (BWPs) including at least one of an active bandwidth part (BWP), receiving a received signal strength indicator (RSSI) measurement configuration and/or a channel occupancy measurement configuration from the network, performing a RSSI measurement and/or a channel occupancy measurement per each of the multiple BWPs, and reporting an identifier (ID) of a specific BWP among the multiple BWPs to the network when a condition related to the RSSI measurement and/or the channel occupancy measurement of the active BWP and the specific BWP is met.
