5G Extreme Requirements: Operators’ Views on Fundamental Trade-Offs

The aim of this work is to highlight what implications and trade-offs related to the delivery of new 5G services are relevant for mobile network operators. Some of these new services, in fact, require extremely low latency and high reliability of the communication link, which have very little in common with the targets that the telecommunications industry has worked towards until today. Mobile cellular networks have in fact traditionally been designed and optimised for the delivery of good voice and data services for mobile broadband customers, so the new 5G requirements now call for a re-think on how the future network will have to be designed and optimised in order to enable the new services. The purpose of this document is to outline relevant trade-offs that need to be taken into account when delivering 5G services. In particular, the interplay among coverage, packet size, data rate, latency, and reliability, is analysed.

Liaison Statement on Technology Evaluation of LTE-V2X and DSRC

The intention of the liaison statement from the NGMN V2X Task-Force to the 5GAA is to inform 5GAA of evaluation results summary on link level simulation (LLS) and system level simulation (SLS) for LTE-V2X performance compared with DSRC performance.

5G E2E Architecture Framework

The purpose of this document is to provide a high-level framework of architecture principles and requirements that provide guidance and direction for NGMN partners and standards development organisations in the shaping of the 5G suite of interoperable capabilities, enablers, and services. It builds on the architectural concepts and proposals implied by the NGMN 5G White Paper and subsequent deliverables published by NGMN. It is anticipated that this document will have versions, beyond an initial version, to reflect additional forward-looking requirements and/or updates as needed.  The elements of functional virtualisation, shift of computing to the edges of the network, and leveraging of spectrum distribution and flexibility, are among the dominant themes that shape the 5G ecosystem. Optimisation of operational and performance efficiencies, while creating and delivering an exceptional and customisable user experience is of paramount significance.

NGMN Paper on 5G End-to-end Architecture Framework

Since communicating an initial set of Architecture Principles to 3GPP TSG WG2 in November 2016 the NGMN Requirements and Architecture (P1) E2E Architecture Framework group has developed their End-to-end Architecture Framework document further. Given the relative timescales of the project and of SA2’s work item for the 5G Architecture - Phase 1 it has been decided to share an interim version of the NGMN Architecture Framework document in order for SA2 to become aware of the additional principles agreed thus far, and to see the full scope of the activity.

NGMN Submission to US Department of Transportation during NPRM Process

In this document sections, the NGMN V2X Task-Force team has outlined its feedback on the "Notice of Proposed Rule Making of US Department of Transportation / NHTSA". This feedback provides information on elements of NHTSA’s proposed rules that are supported by NGMN as well as improvements and changes to other elements of the proposed rules. As elaborated in the following sections, the NGMN V2X Task Force recommends USDOT be technology neutral in the rule making as cellular technologies beginning with 3GPP Release 14 could offer a technical and market-driven solution with a clear evolution path. We view this capability as a technology option that could be deployed well within the deployment horizon envisioned in NHTSA’s proposal and also be compatible with 5G as that deployment matures. This solution appears preferable by many measures including better technical performance, improved cost-efficiencies, and its flexibility to adapt to a variety of business models.

Annex: NGMN IPR Forum Recommendations to Improve SEP Declarations

With reference to IPR, NGMN is developing recommendations and an implementation strategy supporting a more transparent and predictable IPR eco-system for 5G Standards Essential Patents (SEP) across industries that will support sustainable implementation of 5G technologies and ensure that innovation is stimulated and innovators appropriately rewarded. One of the business objectives is to make 5G accessible for all types of devices from high-end smartphones and tablets down to low-end MTC (Machine Type Communication) devices such as smoke detectors and sensors. In support of this objective, the IP licensing terms and conditions for 5G market should be fair, reasonable and non-discriminatory so as to enable sustainable and successful mass deployment of any 5G service or Product Type including MTC devices to support the Internet of Things (IoT). One of the objectives is to improve the transparency of 5G Standard Essential Patent (SEP) Disclosures. In order to achieve this objective, NGMN is requesting Standards Developing Organizations working on 5G technologies to consider the recommendations in the enclosed Annex relating to the disclosure and licensing of patents and patent applications (collectively, “Patents”) as potentially essential to a standard. NGMN is continuing to improve the recommendations and may come up with further updates....

Recommendation on Base Station Antenna Standards (V10.0)

This whitepaper addresses the performance criteria of base station antennas, by making recommendations on standards for electrical and mechanical parameters, by providing guidance on measurement and calculation practices in performance validation and production, and by recommending methods for electronic data exchange.  It also addresses recommendations on applying existing environmental and reliability standards to BSAs.
