Abstract: A method and apparatus for managing dedicated preconfigured uplink resource (D-PUR) configuration for a moving wireless device in a wireless communication system. A radio access network (RAN) node transmits, to a wireless device, a configuration of a dedicated pre-allocated uplink resource (D-PUR) for the wireless device. The RAN node transmits, to a core network node, a first message including information related to the D-PUR for the wireless device. The RAN node receives, from the core network node, a second message informing that the core network node detects an access of the wireless device to another RAN node based on the information related to the D-PUR. The RAN node releases the configuration of the D-PUR for the wireless device.

Abstract: A method and apparatus for controlling mobile early data transmission (EDT) procedure in a wireless communication system is provided. A first core network node, in a wireless communication, receives, from a second core network node, a message for a downlink data including a size of the downlink data. The first core network node determines whether to initiate an early data transmission (EDT) procedure for the downlink data based on the size of the downlink data. The first core network node transmits, to a radio access network (RAN) node, a paging message including information related to the EDT procedure for the downlink data based on the decision to initiate the EDT procedure for a wireless device.

Abstract: A method and apparatus for supporting of inter-gNB handover in higher layer multi-connectivity is provided. A target master node (MN) of an inter-MN handover procedure receives a handover request message including information on a redundancy sequence number (RSN) from a source MN of the inter-MN handover procedure. The information on the RSN informs that a protocol data unit (PDU) session mapped to the RSN is allocated to a secondary node (SN) of the inter-MN handover procedure for redundant transmission.

Abstract: A method and apparatus for allocating resources for vehicle-to-everything (V2X) message transmission in a wireless communication system is provided. For the first solution, a pre-configuration based scheme is defined and specific temporary mobile group identities (TMGIs) are defined for the V2X service. For the second solution, a multi-cell/multicast coordination entity (MCE) receives a request for radio resource, which is based on an amount of V2X messages transmitted from vehicle user equipments (UEs) or road side unit (RSU) UEs, from an eNodB (eNB) supporting V2X function or an eNB type RSU, and transmits multimedia broadcast multicast services　(MBMS) scheduling information to the eNB supporting V2X function or an eNB type RSU as a response to the request for radio resource.
