Abstract: A method and apparatus for discarding a buffered data in a wireless communication system is described. A central unit (CU) user plane (UP) of a gNB receives a buffered data discard indication from a CU-control plane (CU-CP) of the gNB, and discards buffered data for a user equipment (UE) based on the buffered data discard indication. Even after discarding the buffered data, UE context is still kept. The CU-CP is a logical node constituting the gNB that hosts a radio resource control (RRC) protocol and a packet data convergence protocol (PDCP)-C protocol, and the CU-UP is a logical node constituting the gNB that hosts a PDCP-U protocol.

Abstract: Provided are a method and an apparatus for performing a secondary node change procedure disclosed by a source secondary node in a wireless communication system. A master node receives a secondary node change request message from the source secondary node, transmits a secondary node addition request message to a target secondary node, receives a secondary node addition request confirm message from the target secondary node, and transmits a secondary node change request confirm message to the source secondary node.

Abstract: Provided are a method in which a source base station (BS) transmits a Quality of Service (QoS) flow-to-data radio bearer (DRB) mapping rule to a target BS in a wireless communication system, and a device supporting the same. The method may include: receiving, from a user equipment (UE), a measurement result of a target cell; determining the handover of the UE to the target BS on the basis of the measurement result; and transmitting, to the target BS, a handover request message including a QoS flow-to-DRB mapping rule of the source BS.

Abstract: A user equipment can send an EPS mobility management (EMM) message including uplink data to a network node. The user equipment can determine that an EMM process complying with the EMM message has successfully been completed or can treat an EMM process complying with the EMM message as having been successfully completed if the user equipment receives an RRC disconnection, downlink data or service acceptance message for the EMM message.

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.
