Figure 6.1-1: Overall architecture The NG-RAN consists of a set of gNBs connected to the 5GC through the NG interface. The 5G System architecture consists of the following network functions (NF) majority of which constitute the 5GC: Authentication Server Function (AUSF) Core Access and Mobility Management Function (AMF) Data network (DN), e.g. lower latency while the base-station, gNB, will be split in two (central unit, gNB-CU, and distributed unit, gNB-DU). 5g core network architecture 5g core network architecture 3GPP is a standard body that is defining both a new 5G core network (5GC) and a new radio access technology called 5G “New Radio” (NR). 5G Fronthaul Architecture | Time Sensitive Networking. The following shows the high-level architecture of a 5G System (5GS) described in 3GPP TS 23.501 5G System Architecture specification: 5GS Architecture and Network Functions. The split architecture will enable the 5G network to utilize different distribution of protocol stacks between CU and DUs depending on fronthaul (FH) The NG-RAN consists of a set of gNBs connected to the 5GC through the NG interface. 5G NR Radio Protocol Architecture: Scheduling. 5G Radio Network Architecture In 5G, the RAN node is referred to as the Next Generation RAN (NG-RAN). The 5G gNB provides the 5G data path. Radio Access Network (RAN) node connects to the UPF and AMF The NG-RAN node is either a gNB or a ng-eNB, as follows Now one of the popular interfaces in 5G RAN is between RU and DU in 5G fronthaul architecture. Figure 6.1-1: Overall architecture. 5G terminal device such as smartphone, tablet, laptop etc.) 5G RAN Sharing Architecture 5G RAN Sharing shall follow 4G, which includes MORAN and MOCN features. 5G Non-Standalone (NSA) architecture was initially introduced by 3GPP, and its specification was completed in late 2017 to accelerate time to market. Not really, we also have en-gNB (version of NR gNB working under the EN-DC feature within architecture option 3, where the master is LTE eNB connected to EPC), and ng-eNB (version of LTE eNB capable of being connected to 5GC). As non-standalone mode gradually gives way to new 5G mobile network architecture deployments, careful planning and implementation will make this transition seamless for the user base. The architecture also uses the evolved version of 4G-LTE Radio Access Network (eLTE eNB) and Core Network (EPC). 5G Architecture The 5G Radio Network: gNB, AMF, UPF, SMF functions in 5G NR 0 If you are familiar with LTE then it will be easy for you to understand gNB, AMF, UPF, SMF functions in 5G. The system architecture of 5G brings enhancements such as slicing and service based architecture (SBA) allowing enhanced flexibility together with simpler means for business partners. An gNB can support FDD mode, TDD mode or dual mode operation. As shown, NG-RAN composed of gNBs (i.e. Solution Architecture/ ISG Keysight Tony Wang 5G gNB Testing With High-Performance User Equipment Simulation. In SA operation, the gNB is connected to the 5G Core Network (5GC); in NSA operation, NR and LTE are tightly integrated and connect to the existing 4G Core Network (EPC), leveraging Dual Connectivity (DC) towardtheterminal.InaDualConnectivityarchitecture,aMasterNode(MN) and a Secondary Node (SN) concurrently provide radio resources towards the terminal for enhanced end-user bit rates. 10.1 Basic Scheduler Operation. RU and DU functions are described as below. Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM. NR, gNB, NG-RAN and 5GC - Why 5G is complex? The distributed module gNB-DU supports one or more cells and can only be attached to one central module gNB-CU. The NG-RAN consists of a set of radio base stations (known as gNBs) connected to the 5G core network (5GC) and to each other. 5G gNB Architecture . The gNB-CU terminates the F1 interface connected with the gNB-DU. In order to utilise radio resources efficiently, MAC in gNB includes dynamic resource schedulers that allocate physical layer resources for the downlink and the uplink. beginning for 5G. Recently (on 20th of December 2017) at Lisbon – Portugal during the 3GPP’s quarterly plenary meeting, announced the completion of first 5G NR specifications. Architecture 5G base station gNB. In this article general overview of 5G will be described, we need to remind that the 3GPP technical specifications for 5G are not fully completed yet. This is as defined in the 3GPP TS 38.300 specification. gNB, in SA mode, provides NR use r plane and control plane protocol terminations towards the UE (i.e. Both LTE eNB & NR gNB … A new use of dual connectivity has also been applied to use LTE/eLTE and NR as the master or secondary radio access technology (RAT) in different combinations. Published on August 16, 2018 August 16, 2018 • 340 Likes • 20 Comments and finally in 5G we have next generation NodeB, but the short name is gNB. 5G Base stations) and ng-eNBs (i.e. 5G will also see several enhancements from operator services, Internet access or 3rd party services Although, some types of gNB may connect to the 4G EPC instead of 5G Core. The gNB handles radio communications with the 5G capable User Equipment (UE) using the 5G New Radio (NR) air interface. 5G standalone mode is essentially 5G deployment from the ground up with the new core architecture and full deployment of all 5G hardware, features and functionality. 5G NG-RAN architecture Source: 3GPP A gNB may consist of a gNB-CU (Central Unit) and one or more gNB-DUs (Distribution Unit). In summary, the gNB handles radio communications with the 5G capable UE using the 5G NR (New Radio) air interface. gNBs can be interconnected through the Xn interface. The 5G architecture introduces a New Radio Access Network (gNB) and Next-Generation Core Network (5GC) to support the diverse range of services specified by 3GPP. The gNB may consist of a Centralized Unit (CU) and one or more Distributed Units (DUs) connected to the CU via Fs-C and Fs-U interfaces for CP and UP respectively. 5G NR overall architecture is shown in the following figure-2. Figure 1. There are several options available to integrate between different generations of access network technology with the core network. 38300 3GPP NR Release 15. This has resulted in six connectivity options for a UE, as shown in Figure … gNBs can be … 5GPPP Architecture Working Group View on 5G Architecture Version 2.0, December 2017 Date: 2017-12-15 Version: 2.0 Feb, 2019 by Pankaj in 5G, 5G Architecture, NG-RAN Architecture gNB Central Unit (gNB-CU): a logical node hosting RRC, SDAP and PDCP protocols of the gNB or RRC and PDCP protocols of the en-gNB that controls the operation of one or more gNB-DUs. In Release 15, the 3GPP has defined multiple architectural options for a UE to connect to the network, using LTE/eLTE and/or NR access to connect to Evolved Packet Core (EPC) or 5G Core (5GC) networks. "early Rel-15 drop": focus on architecture option 3, also called non-standalone NR (NSA NR) which could be considered as the first migration step of adding NR base stations (called gNB) to an LTE-Advanced system of LTE base stations (eNB) and an evolved packet core network (EPC) i.e. gNB Cell Addition Process In NSA Architecture: Step 1: The UE first attaches to the 4G network and signals to the EPC that it supports dual connectivity to 4G and 5G networks (via DCNR bit set to 1 in the attach message). Let us turn to the ng-eNB. An gNB can support FDD mode, TDD mode or dual mode operation. 5G fronthaul architecture. 5G RAN Architecture The 3GPP 5G RAN architecture – specified in Release 15 and known as NG-RAN – introduces new terminology, interfaces and functional modules. The gNB in its most basic form connects to the 5G Core network through the NG reference points although some types of gNBs may connect to the 4G EPC instead of 5G Core. The gNB-CU and gNB-DU modules are connected by a logical interface F1. A gNB-CU and a gNB-DU is connected via F1 interface. A gNB-CU and the gNB-DU units are connected with F1 logical interface. The 5G gNB acts as a secondary node in a dual connectivity setup. Software Benefits: Compatibility: The Access Software solution can be ported and integrated on any target SoC. The gNB handles the secondary carrier addition request from the … It was Non-standalone 5G […] LTE base stations). 3GPP has defined 5G architecture in TS 23.501 as illustrated in Figure 1 (below). 5G NSA is the most suitable solution for 5G early deployment and for complementing NR coverage as full mobility with LTE is supported. N1 uses N2 to transport its traffic within the network. A gNB may consist of a gNB-CU and one or more gNB-DU(s). 2 COMPONENTS & CHIPSETS DEVICES BASE STATIONS HYPERSCALE AND DATA CENTERS ENTERPRISE Keysight Classic Ixia Anite Layers 2-7 Layer 1 … The lower layer split between gNB-CU and gNB … The 5G NR network composed of NG RAN (Next Generation Radio Access Network) and 5GC (5G Core Network). 5G architecture is an evolution of current 4G architectures but based on a Service-Based Architecture (SBA). Consider the initial deployment for 5G will be with Non Standalone Architecture (5G NSA) option 3x (EN-DC), we could think of following 4 options for RAN sharing. But is this the whole truth? We build architectural narratives aiming to create a unique spatial experience. 3GPP 5G architecture Within 3GPP standards, there is a clear functional separation between RAN and 5G core specified as the N1, N2 and N3 reference points. 23.501 as illustrated in figure 1 ( below ) RAN is between RU and DU in,!
