摘要： Embodiments of a Next Generation Node B (gNB) are described herein. The gNB may be configured with logical nodes, including a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU may comprise a gNB-CU control plane (gNB-CU-CP) for control-plane functionality, and a gNB-CU user plane (gNB-CU-UP) for user-plane functionality. The gNB may initiate an E1 interface setup procedure, a bearer context setup procedure, and a UE context setup procedure to establish a UE context that includes a signaling radio bearer (SRB) and a data radio bearer (DRB) configuration. The UE context setup request message may be configured to include quality-of-service parameters for the DRB configuration.

摘要： Functions of base station (BS) can be separated into a central unit control plane (CU-CP) for control plane functions, central unit user plane (CU-UP) for user plane functions and a distribution unit (DU) for user equipment communication functions. For example, the control plane (CP) of a base station is split, centralizing part of the CP in a Central Unit (CU). The user plane (UP) of the air interface is partitioned and part of the UP of the air interface and UP of the backhaul is centralized in a CU that can be co-located with the CU hosting the CP, or in a different location, while leaving the rest of the UP of the air interface distributed. Control plane/user plane (C/U) separation, user-plane partitioning and modular design can improve latency and/or bandwidth of interfaces, mobility among BS's, flexible deployment of RAN functions, and the virtualization of the CP and/or the UP.

摘要： A centralized RAN architecture that includes lower layer transmission nodes (referred to as distributed units (DUs) herein) that connect to an upper layer RAN node (referred to as a centralized unit (CU) herein). A centralized RAN architecture may include a functional split, between the CU and DU, corresponding to the Packet Data Convergence Protocol (PDCP) and Radio Link Control (RLC) layers. In one embodiment, a CU may store copies of downlink PDCP PDUs that are transmitted to a first DU. The CU may retransmit, to a second DU, those of the PDCP PDUs which were previously transmitted to the source DU but have not been acknowledged as successfully delivered by the source DU.

摘要： An SDN architecture, for a cellular communications system, separates the control plane and the user plane in a RAN of the cellular communication system. A controller, in the RAN, may serve a number of base stations and perform mobility management control functions (i.e., functions related to handovers), via a control plane, for base stations in the RAN. User plane traffic may be separately communicated between base stations and an SDN switch. The SDN switch, in the RAN, may be used to route data plane traffic and terminate the backhaul connection towards the core network.

摘要： Radio access network (RAN) architectures and associated network entities are discussed. In one example RAN architecture, control plane (CP) and user plane (UP) functionality can be split. The RAN controller can exchange a first set of control messages with the SDN switch via a first interface associated with routing, encapsulation, or decapsulation of user data messages, and can exchange a second set of control messages with one or more base stations (BSs) via a second interface associated with control of an air interface. The SDN switch can also route uplink and downlink user data between the one or more BSs and the core network via third and fourth interfaces. The BSs can facilitate exchange of control messaging between the RAN controller and one or more user equipments (UEs), and exchange of uplink and downlink user data between the UE(s) and the core network via the SDN switch.

摘要： An apparatus of a next generation NodeB (gNB) comprises one or more baseband processors to interconnect a gNB Central Unit control-plane entity (gNB-CU-CP) with a gNB Central Unit user-plane entity (gNB-CU-UP) via an E1 control plane interface and a gNB Distributed Unit (gNB-DU) via an F1 control plane interface. Rather than relying on multiple class-1 procedures initiated by gNB-CU-CP toward gNB-CU-UP and gNB-DU, the one or more baseband processors are configured to establish or modify a bearer context and to communicate data transport tunneling and/or packet data convergence protocol (PDCP) preservation status information for a specific user equipment (UE), utilizing the direct F1 user plane interface between gNB-DU and gNB-CU-UP to avoid relaying delay. The gNB can include a memory to store the bearer context and data transport tunneling information.

摘要： Embodiments of an Evolved Node-B (eNB), radio access network (RAN) central unit (RCU) and methods for radio resource control (RRC) are generally described herein. A RAN distributed unit (RDU) at an eNB may communicate with an RCU of a cloud RAN to cooperatively perform RRC functionality for the eNB 104. The RDU 105 may receive a request for an RRC connection from a User Equipment (UE), and may request global load information from the RCU. The RDU may determine whether to establish the requested RRC connection based on the global load information when a response from the RCU is received before a predetermined time. The RDU may determine whether to establish the requested RRC connection based on local load information when the response from the RCU is not received before the predetermined time.

摘要： Embodiments of a Master Evolved Node-B (MeNB), a software-defined network (SDN) switch, and methods for multiple bearer connectivity are generally described herein. The MeNB may receive, from a software-defined network (SDN) switch, a data packet to be forwarded to a User Equipment (UE) as part of a first Evolved Packet System (EPS) bearer between a Serving Gateway (S-GW) and the UE. The MeNB may transmit the data packet to the UE on a first radio bearer included in the first EPS bearer. The MeNB may further transmit, to the SDN switch, a configuration message to identify a second EPS bearer between the S-GW and the UE. The second EPS bearer may include a second radio bearer between the UE and a secondary Evolved Node-B (SeNB), and may exclude radio bearers between the UE and the MeNB.
