201117 NGMN E2EArchFramework v4.31

5G End-to-End Architecture Framework v4.31

//in , //by

This document delineates the requirements in terms of entities and functions that characterise the capabilities of an E2E (end-to-end) framework. Architectural perspectives and considerations associated with the service categories – eMBB, mIoT, URLLC – envisioned for 5G (Fifth Generation) underscore the delineation of the E2E framework requirements. These requirements are intended as guidance in the development of interoperable and market enabling specifications for a continuing advancement of the 5G ecosystem of heterogenous access, virtualization, autonomic capabilities, forward-looking service enablers, and emerging usage scenarios.

NGMN 5G White Paper 2

5G White Paper 2

//in , //by

NGMN published its first 5G White Paper in 2015, providing an operator vision of 5G and serving as a guideline for 5G definition and design. Since then, the White Paper has been referenced by standards development and industry organisations when producing 5G specifications and promoting the 5G ecosystem.
This second 5G White Paper begins with a review and expansion of the vision in the first 5G White Paper. It then highlights some of the vertical industries that 5G will progressively support, showing how mobile network operators can provide both network and services to meet the varied requirements of the different markets. A high-level description is provided of key technology enablers that have matured or been identified since the first 5G White Paper, and that are required to meet the Verticals’ requirements. Specific consideration is given to sustainability, the latest considerations and recommendations on IPR and spectrum are provided, and we conclude with some key messages and actions to industry. Sections listing abbreviations, definitions and references then complete the document.

NGMN RF Cluster Connector White Paper Phase 2 v1 5

Recommendation on RF Cluster Connector – Antenna to Radio Module Pinout Alignment

//in , //by

This White Paper adresses the alignment of 8T8R antenna and 8T8R radio module pinout with a unique naming system and pinout order on repeatable basis to simplify rigging of installations. This shall help to mimimise the potential for cross feeder/connection issues.

The goal is to have one simple naming convention which allows different vendors to manufacture only one product  variant to simplify deployment logistics and future site maintenance.

This document is the output of Phase 2 of the NGMN cluster connector project.

NGMN BASTA AA WP 1 0

Recommendation on Base Station Active Antenna System Standards

//in , //by

The main scope of this White Paper is to describe and capture the electrical and mechanical key performance parameters of Active Antenna Systems and how to exchange this data electronically.

In addition, for the aim of RF-Electromagnetic Field exposure, a description of mechanisms to monitor and limit the power radiated by Active Antenna Systems is provided.

NGMN Security Consideration of Low Layer Split in O-RAN

//in , //by

In this Liaison Statement from NGMN to the O-RAN Alliance, the NGMN Alliance informs O-RAN that the security of low layer split in O-RAN needs to be globally considered. Security considerations on threats depend on the deployment model and use case. NGMN therefore proposes a two-phase approach to mitigate such threats.

200114 5G Devices Categorization v1.2

5G Devices Categorization

//in , //by

The purpose of this document is to provide a use-case based categorization of 5G Devices implementing 3GPP Rel-15 relevant Technical Specifications.

In particular, 5G Devices coming to market between 2H 2019 and 1H 2020 are addressed.

For each 5G Devices category (among eMBB, Fixed Wireless Access and Industrial), a set of mandatory and recommended features is defined.

210406 NGMN PrecomNW Trials Major Conclusions v2 1

Pre-Commercial Networks Trials Major Conclusions

//in , //by

Given the freeze of 3GPP Release 15 5G standards and the onset of some initial 5G commercial deployments in countries such as South Korea, many operators accelerated their 5G trials in 2019.

As a part of NGMN 5G Trial and Testing Initiative (TTI) project, some major NGMN operators, shared their initial 5G trial results.

Pre-commercial network trials phase of 5G TTI aims to consolidate the results from different operators and reach some major conclusions.

Overall, this consolidation effort, which gathers Trial reports mostly performed using a common methodology, permits to draw some very promising conclusion on the performances of early 5G implementations. Additionaly, it brings as well some observations that could lead to future improvements.

Ideas for Small Cell Cost Sharing – Short Report

//in , //by

There is a long held vision of very high capacity networks using small cells in areas of high demand. With the expected availability of large quantities of mmWave spectrum for 5G, this opportunity in principle becomes even greater. But the economics of small cell deployment have proved very challenging in practice – and this challenge will only increase at mmWave frequencies, where coverage of an individual cell is typically even smaller. Unless the industry can find ways to reduce the per cell building, operation and maintenance costs, the opportunity to build out small cell networks using mmWave spectrum will be severely constrained.

NGMN carried out a study to identify and assess different approaches to improving the economics of small cells through some form of cost sharing between operators (with 5G small cells typically anchored to a 5G or LTE coverage layer). This short public report presents the most important and interesting ideas arising from that study. A fuller report from the NGMN study is also available

This NGMN report aims to identify and assess different approaches to improving the economics of small cells through some form of cost sharing between operators (with 5G small cells possibly anchored to an LTE coverage layer). This study considers different economic models (including such as independent “neutral host” or jointly owned infrastructure companies) as well as technology aspects.
