C-V2X Communications for the Support of a Green Light Optimized Speed Advisory (GLOSA) Use Case, Journal of Telecommunications and Information Technology, 2021, nr 2

Rapid expansion of 5G affects a number of sectors, including vehicular communications relying on cooperative intelligent transportation systems (C-ITS). More specifically, in the context of the Internet of Vehicles (IoV), a particular emphasis is placed on modern cellular V2X (C-V2X) technologies aiming to further improve road safety. This work originates from the detailed scope of the ongoing 5G-DRIVE research project promoting cooperation between the EU and China, with the aim of demonstrating IoV services that rely on vehicle-to-infrastructure (V2I) communications. With the C-V2X approach serving as a point of departure, we analyze and describe a specific green light-optimized speed advisory (GLOSA) use case, for which we provide a detailed descriptive framework, a proposed architectural framework for trials, as well as specific KPIs for the joint assessment of trials between the EU and China. We also discuss the context for performance test procedures to be conducted as part of the intended trials. GLOSA provides end-users with short-term information on upcoming traffic light status to optimize traffic flows, help prevent speed limit violations, improve fuel efficiency, and reduce pollutio

Implications of multi-tenancy upon RRM/Self-x functions supporting mobility control

Based on the context of the original SESAME project research effort, in the present work we examined the implications of multi-tenancy upon the Radio Resources Management (RRM) and Self-x functions that support mobility control, as the latter is a fundamental functionality to ensure a seamless experience to the user equipments of the different operators when moving across the cells of a shared RAN (Radio Access Network) and when entering and leaving the shared infrastructure.Peer ReviewedPostprint (published version

Energy Efficiency Concerns and Trends in Future 5G Network Infrastructures

Energy efficiency is a huge opportunity for both the developed and the developing world, and ICT will be the key enabler towards realising this challenge, in a huge variety of ways across the full range of industries. In the telecommunications space in particular, power consumption and the resulting energy‐related pollution are becoming major operational and economical concerns. The exponential increases in network traffic and the number of connected devices both make energy efficiency an increasingly important concern for the mobile networks of the (near) future. More spe-cifically, as 5G is being deployed at a time when energy efficiency appears as a significant matter for the network ability to take into account and to serve societal and environmental issues, this can play a major role in helping industries to achieve sustainability goals. Within this scope, energy efficiency has recently gained its own role as a performance measure and design constraint for 5G communication networks and this has identified new challenges for the future. In particular, the inclusion of AI/ML techniques will further enhance 5G’s capabilities to achieve lower power consumption and, most importantly, dynamic adaption of the network elements to any sort of energy requirements, to ensure effective functioning.</p

Testing Plan Description and Field Measurements for Real-Time Wide Area Monitoring of Interconnected Power Systems in the Smart5Grid Project

This paper outlines the testing plan and the field measurement results employed in the development and implementation of Smart5Grid’s UC#4 – Real-Time Wide Area Monitoring (WAM) of interconnected systems. As the integration of 5G infrastructure gains prominence in the Information and Communication Technology (ICT) domain, Smart5Grid leverages the capabilities of 5G Networks to enhance smart grid functionalities. The testing plan encompasses rigorous assessment procedures to evaluate the network performance in terms of Delay, Reliability and Availability of Smart5Grid in diverse operational scenarios between the two neighbouring countries of Greece and Bulgaria. Through detailed field measurements gathered by the Phasor Measurement Units (PMUs), this study aims to validate the system's capability in seamlessly integrating distributed energy resources, optimizing grid performance, ensuring reliability and facilitating dynamic response to evolving demands and conditions. The findings from these field measurements provide valuable insights into the effectiveness and viability of integrating 5G technologies into Smart5Grid, contributing to advancements in the development of next-generation smart grid solutions.</p

A Novel Architectural Concept for Enhanced 5G Network Facilities

The 5G ESSENCE project’s context is based on the concept of Edge Cloud Computing and Small Cell-as-a-Service (SCaaS) -as both have been previously identified in the SESAME 5G-PPP project of phase 1- and further “promotes” their role and/or influences within the related 5G vertical markets. 5G ESSENCE’s core innovation is focused upon the development/provision of a highly flexible and scalable platform, offering benefits to the involved market actors. The present work identifies a variety of challenges to be fulfilled by the 5G ESSENCE, in the scope of an enhanced architectural framework. The proposed technical approach exploits the profits of the centralization of Small Cell functions as scale grows through an edge cloud environment, based on a two-tier architecture with the first distributed tier being for offering low latency services and the second centralized tier being for the provision of high processing power for computing-intensive network applications. This permits decoupling the control and user planes of the Radio Access Network (RAN) and achieving the advantages of Cloud-RAN without the enormous fronthaul latency restrictions. The use of end-to-end network slicing mechanisms allows for sharing the related infrastructure among multiple operators/vertical industries and customizing its capabilities on a per-tenant basis, creating a neutral host market and reducing operational costs
