CONTENTS

This course provides a thorough overview of the Next-Generation Radio Access Network (NG-RAN) which is part of the 3GPP 5G System. The focus is on Stand-Alone (SA) operation but also Non-Stand Alone (NSA) NR is outlined.

The course starts with a brief introduction to the 5G System, followed by a discussion of aspects of the new radio interface and the nodes, interfaces and procedures in the NG-RAN. The course also describes various RAN – core option and dual connectivity options as well as some NG-RAN implementations such as C-RAN, O-RAN (from O-RAN Alliance) and IAB (Integrated Access and Backhaul).

PREREQUISITES

Knowledge of LTE/4G is required. Basic knowledge of the overall 5G System is recommended. Good 5G background knowledge is provided e.g. by Apis’ 5G System Overview course.

5G System Overview

  • 5G System introduction, new Network Functions and Service Based Architecture
  • E-UTRAN and NG-RAN elements: gNB, eNB, ng-eNB, en-gNB
  • Non-Stand Alone (NSA) and Stand-Alone (SA) deployment options
  • PDU Sessions and QoS flows

New Radio (NR) Fundamentals

  • NR frequency bands, cell bandwidth, carrier aggregation, millimetre waves
  • OFDM NR numerologies, frame and slot structure
  • Differences between NR and E-UTRA

Non Stand-Alone NR with EPC

  • Architecture for NSA NR
  • E-UTRA – NR Dual Connectivity (EN-DC)
  • Radio Bearers and CN Connections
  • Handling of control plane and user plane
  • The Xn interface

Stand-Alone NR with 5GC

  • Architecture for SA NR
  • NR – NR Dual Connectivity (NR-DC)
  • Radio Bearers and CN Connections
  • Handling of control plane and user plane

NG-RAN Protocols

  • Overview of NG-RAN interfaces and protocols
  • N2/N3/NG interfaces and NGAP protocol functions
  • Xn interface and XnAP protocol functions
  • RRC, SDAP, PDCP, RLC and MAC

NR Uu Channel Architecture

  • Overview of the radio interface protocol stack
  • Layer 2 protocols: SDAP, PDCP, RLC, MAC
  • RLC Channels, Logical Channels, Transport Channels and Physical Channels

RRC and RRC States

  • RRC Overview
  • RRC States
  • Behavior of Network and UE in IDLE, CONNECTED and INACTIVE states
  • RAN Notification Areas

C-RAN – Centralized RAN

  • Reasons for C-RAN
  • Architecture options: gNB Central Unit and Distributed Unit
  • gNB-CU Control Plane and User Plane separation
  • F1-C, F1-U interfaces
  • F1AP – F1 Application Protocol
  • E1 interface
  • E1AP – E1 Application Protocol

O-RAN Architecture

  • Reasons for O-RAN
  • Relation to 3GPP specifications
  • O-RAN Architecture and Interfaces (A1, E2, O1, O2)
  • Non-RT vs Neal-RT RAN Intelligent Controller (RIC)

Integrated Access and Backhaul (IAB)

  • IAB Architecture: IAB-donor and IAB-node
  • Bandwidth Adaptation Protocol (BAP)

Interworking with LTE/EPS

  • Some interworking scenarios and issues between 5G and 4G
  • Handover traffic case
This course provides a thorough overview of the Next-Generation Radio Access Network (NG-RAN) which is part of the 3GPP 5G System. Both Non-Stand Alone (NSA) and Stand-Alone (SA) operation options are described.
