Abstract: A new cell specification procedure can be defined, in order to support more efficiently a network slice function in a new radio (NR) access technology as being a part of a 5G communication system. From a perspective of a radio access network (RAN)-core network (CN) interface, a RAN node can transmit, to a CN node, a first indicator related to the slice support of the RAN node, and receive, from the CN node, a second indicator related to the slice support of the CN node.

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: Disclosed is a method for effectively performing a non-access stratum (NAS) rejection when performing RRC connection resume in a wireless communication system. A method for performing, by a base station, radio resource control (RRC) connection resume in a wireless communication system, includes performing an RRC connection resume procedure with a user equipment (UE), transmitting a resume request message to a mobile management entity (MME), and receiving a resume failure message including an NAS rejection cause from the MME when the resume request has not been permitted.
