Abstract: A new cell specific procedure and/or a mobility procedure may be defined to more efficiently support a network slice function in new radio access technology (NR), which is a part of a 5G communication system. In terms of a radio access network (RAN)-RAN interface, the cell specific procedure comprises that a first RAN node transmits a first indicator related with the slice support of the first RAN node to a second RAN node, and receives from the second RAN node a second indicator related with the slice support of the first RAN node. The mobility procedure comprises that a target RAN node transmits a path change request message including slice-related information to a core network (CN) node, and receives from the CN node a path change response message including at least one of a common control plane function (C-CPF) identifier (ID), a finally selected slice-related ID or U-Plane information.

Abstract: A method and apparatus for indicating vehicle-to-everything (V2X) or road side unit (RSU) function support in a wireless communication system is provided. A radio access network (RAN) node may transmit an indication of V2X/RSU function support of the RAN node to another RAN node. Alternatively, if the RAN nodes does not support V2X/RSU function, the RAN node may transmit a message including a cause value indicating that the RAN node does not support V2X/RSU function.

Abstract: Upon receiving an uplink (UL) V2X message from a vehicle user equipment (UE) or a road side unit (RSU) UE, a vehicle-to-everything (V2X) application server determines information on resource allocation for a downlink (DL) V2X message and transmits the information on resource allocation to a multi-cell/multicast coordination entity (MCE). The MCE (for multimedia broadcast multicast services (MBMS) based resource allocation scheme) or an eNB (for single-cell point-to-multipoint (SC-PTM) resource allocation scheme) allocates resources for the DL V2X message based on the received information on resource allocation.

Abstract: Provided is a method for a base station performing a multimedia broadcast multicast service (MBMS) session update in a wireless communication system, and a device supporting same. The base station may comprise: receiving, from a multi-cell coordination entity (MCE), a MBMS session update request message comprising a single-cell point-to-multipoint (SCPTM) transmission stop indication; and transmitting, to the MCE, a MBMS session update response message as a response to the MBMS session update request message.

Abstract: Provided are a method by which a base station controls the access of a terminal, and a device for supporting the same. The method comprises the steps of: receiving, from a core network, information on an RRC connection procedure in which access in an RRC inactive state is restricted; receiving a request for executing the RRC connection procedure from a terminal which is in the RRC inactive state; and transmitting, to the terminal, a message notifying that the requested execution of the RRC connection procedure has been restricted, when the RRC connection procedure requested from the terminal corresponds to the RRC connection procedure in which the access is restricted.

Abstract: Provided are a method and an apparatus for transmitting a maximum stratum level in a wireless communication system. An evolved NodeB (eNB) or a home eNB (HeNB) having a global positioning system (GPS) constitutes a maximum stratum level indicating a maximum value of a hop capable of supporting radio interface based synchronization (RIBS) and transmits the constituted maximum stratum level to a small cell. Meanwhile, the small cell determines whether a stratum level is greater than the maximum stratum level, and transmits the maximum stratum level to the eNB or the HeNB having the GPS when the stratum level is greater than the maximum stratum level.

Abstract: A method and apparatus for supporting a local gateway (L-GW) service in a wireless communication system is provided. When an L-GW is co-located with a master evolved NodeB (MeNB) in dual connectivity, a secondary evolved NodeB (SeNB) in dual connectivity receives a request message including information on a specific E-UTRAN radio access bearer (E-RAB), which is served by a L-GW, from a master evolved NodeB (MeNB) in dual connectivity which has the L-GW, decides to transmit data via a X2 interface instead of a S1-U interface for the specific E-RAB, and transmits a response message to the MeNB.
