    摘要: Provided are a method for performing uplink data fast transmission. According to an embodiment of the present disclosure, the method includes receiving a UE context release message including a user plane ID (UPID) from control plane (CP) of a central unit (CU) of the network node, forwarding the UPID via a radio resource control (RRC) connection release message to a wireless device, receiving a RRC resume request message including user data with the UPID from the wireless device, transmitting the user data to CU based on the UPID.

    摘要: 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.

    摘要: 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.
