Abstract: A method and apparatus for sidelink resource handling for central unit (CU)-distributed unit (DU) split based vehicle-to-everything (V2X) communication is provided. A gNB central unit (gNB-CU) in a wireless communication system receives, from a wireless device, information related to a radio access technology (RAT) for which a sidelink resource is requested. The gNB-CU transmits, to a gNB distributed unit (gNB-DU), the information related to the RAT for sidelink resource allocation.

Abstract: A method and apparatus for support of load balancing for supplementary uplink (SUL) in central unit (CU)-distributed unit (DU) architecture in a new radio access technology (NR) is provided. A gNB central unit (gNB-CU) receives, from at least one gNB distributed unit (gNB-DU), information related to a load status of supplementary uplink (SUL) for the at least one gNB-DU, and determines to adjust at least one parameter related to the SUL for a gNB-DU, among the at least one gNB-DU, based on the information related to the load status of the SUL for the gNB-DU. Upon receiving information related to the at least one parameter related to the SUL from the gNB-CU, the gNB-DU may adjust the at least one parameter related to the SUL based on the information related to the at least one parameter related to the SUL.

Abstract: A method and an apparatus in which long-term evolution (LTE) and new radio access technology (NR) coordinate/negotiate information on user equipment (UE) capabilities when the LTE and the NR are linked through a dual connection in a wireless communication system. A first radio access network (RAN) node transmits the UE capability already used by the first RAN node and/or the UE capability remaining or recommended to be used by a RAN node 2 to the second RAN node. The second RAN node transmits the UE capability to be used by the second RAN node to the first RAN node on the basis of the received information.

Abstract: Provided are: a method by which a central unit (CU) of a base station updates access control barring (ACB)-related parameters in a wireless communication system; and an apparatus for supporting the same. The method comprises the steps of: receiving information indicating a change in the ACB-related parameters; updating the ACB-related parameters based on the received information; and transmitting the updated ACB-related parameters to a distributed unit (DU) of the base station.

Abstract: A method and apparatus for support of load balancing for supplementary uplink (SUL) in central unit (CU)-distributed unit (DU) architecture in a new radio access technology (NR) is provided. A gNB central unit (gNB-CU) receives, from at least one gNB distributed unit (gNB-DU), information related to a load status of supplementary uplink (SUL) for the at least one gNB-DU, and determines to adjust at least one parameter related to the SUL for a gNB-DU, among the at least one gNB-DU, based on the information related to the load status of the SUL for the gNB-DU. Upon receiving information related to the at least one parameter related to the SUL from the gNB-CU, the gNB-DU may adjust the at least one parameter related to the SUL based on the information related to the at least one parameter related to the SUL.

Abstract: For supporting selection/authorization of network slicing, a radio access network (RAN) node in a new radio access technology (RAT), e.g. gNB, receives a service request including slice information from a user equipment (UE), and determines a slice based on the slice information. The RAN node forwards the service request including the slice information to a common control plane function (C-CPF), and then, the C-CPF checks whether the UE is authorized for a specific slice. The RAN node receives a service response including an authorization indication for the specific slice from the C-CPF, and performs a corresponding action for the specific slice.

Abstract: As one aspect of mobility enhancement of 3rd generation partnership project (3GPP) long-term evolution (LTE)-wireless local area network (WLAN) aggregation, inter-eNodeB (eNB) handover without WLAN termination (WT) change is considered. A source eNB transmits a handover request message including a WT identifier (ID) and WT XwAP ID to a target eNB. The target eNB transmits a WT addition request message including the WT XwAP ID to a WT, and receives a WT addition request acknowledge message from the WT. The target eNB transmits a handover request acknowledge message indicating that a WT is kept to the source eNB. The source eNB transmits a WT release request message indicating that the WT is kept to the WT. The WT is a logical node that terminates a Xw interface on a WLAN.
