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: Provided are a method in which a source distribution unit (DU) of a base station stops transmitting data to a user equipment (UE) in a wireless communication system, and an apparatus supporting the method. The method may include: receiving, from a central unit (CU) of the base station, a message indicating to stop transmitting data to the UE; and stopping transmitting data to the UE, upon receiving the message from the CU of the base station.

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: When a user equipment (UE) requests a service simultaneously during a mobility management (MM) attach procedure in a new radio access technology (NR; or new RAT) system, slice related information may be transmitted together. In detail, a radio access network (RAN) node receives a network connection request, a service request and slice related information from the UE, and routes the network connection request, the service request to a dedicate common control plane function (C-CPF) according to the slice related information.

Abstract: Proposed are a method for receiving, by a base station (BS), authorization information on a network slice in a wireless communication system, and an apparatus supporting the same. The method may include: receiving an attach request from a user equipment (UE); selecting a common control plane function (C-CPF) corresponding to a particular network slice based on the attach request; transmitting the received attach request to the selected C-CPF; and receiving authorization information, which indicates whether the UE is authorized to use the particular network slice, from the selected C-CPF.
