5G LENA: An E2E Simulator for 5G NR Networks – Models and evaluations in licensed and unlicensed bands
ABSTRACT: As 3GPP proceeds with its specification work for 5G and Beyond, the availability of a versatile, full-stack, end-to-end and open source simulator, to reproduce with high fidelity performance and behaviour of New Radio (NR) technology, becomes a necessity to bring forward research in the area of 5G and Beyond mobile neworks.
In this talk I will introduce an extension to the widely adopted ns-3 simulator, a well-known discrete-event network simulator, to support the NR Radio Access Network. I will focus on main design and implementation choices for the RAN, and introduce extensions to model NR-U for coexistence in unlicensed bands with IEEE 802.11 technologies. Finally, I will present a coexistence discussion and performance analysis between NR-U and IEEE 802.11ad Wireless Gigabit (WiGig) in mmWave unlicensed spectrum.

In September 2007 she joined the CTTC where she is currently a Senior Researcher in the Mobile Networks Department. Her research experience falls in the area of RAN and spectrum management, self-organizing networks (SON), LTE, NR, NR V2X, coexistence in unlicensed spectrum, O-RAN, mmWave, simulation modelling. Since 2015 she is a member of the Executive Committee of the ns3 consortium. She is the co-recipient of the IEEE Consumer Communications and Networking Conference 2010 (IEEE CCNC 2010), of the IEEE third International workshop on Indoor and Outdoor Femto Cells 2011 2011 and of 2018 IEEE Wireless Commun. and Networking Conference best paper awards. Over the years, she has led and participated in multiple EU (in FP6, FP7 and H2020, 5GPPP), national (she was the Principal Investigator of three projects funded by the Spanish national research program) and industrial projects (funded by the WiFi Alliance, Spidercloud Wireless, Interdigital, National Institute of Standards and Technologies, Lawrence Livermore National Lab.)
ns-3 as a Digital Twin for Wireless Testbeds
ABSTRACT: In wireless networking R&D we typically depend on simulation and experimentation to evaluate and validate new networking solutions. In the one hand, simulation allows full control over the scenario conditions, although its accuracy is limited by the existing models which are inherently simplifications of the real world. On the other hand, real-world experimentation is influenced by external random phenomena and may produce hardly repeatable and reproducible results. Therefore, we may end up with a limited performance evaluation and validation of new networking solutions. To overcome this problem, we propose the use of ns-3 as a “digital twin” for wireless testbeds, by using SNR, PHY-rate and channel occupancy traces from real experiments to replicate the real-world conditions in ns-3. Having an ns-3 “digital twin” of the testbed allows, then, to reproduce the real experiments and related results in ns-3, and keep improving the solution under evaluation even if the real testbed is not available. The talk will briefly introduce ns-3, followed by a presentation of the three trace-based ns-3 simulation models developed by INESC TEC to achieve this goal (soon to be added to the ns-3 app store). The talk will focus on Wi-Fi experiments and include an overview on how to capture the necessary traces and run the related trace-based simulations in ns-3.

UAV-Enabled Wireless-Powered Mobile Edge Computing System
ABSTRACT: Motivated by the ever increasing computational capacity of wireless local devices as well as the ever increasing concerns on sharing data due to privacy and security, next-generation communications/computing networks has been encountering a paradigm shift from conventional cloud computing to edge computing, which largely deploys computational power to the network edge nodes and devices to meet the needs of applications that demand very high computations and low latency. Recently, unmanned aerial vehicle (UAV)-enabled MEC architectures have been proposed by integrating UAV into MEC networks. In those architectures, an UAV can be considered as a user that has computation tasks to be executed, or a relay to assist users for ofﬂoading computation tasks, or an MEC server for executing computation tasks. This talk focuses on an unmanned aerial vehicle (UAV)-enabled MEC wireless-powered system by using UAV as the MEC server. The computation rate maximization problems in a UAV-enabled MEC wireless powered system are investigated under both partial and binary computation ofﬂoading modes, subject to the energy-harvesting causal constraint and the UAV’s speed constraint. A two-stage algorithm and a three-stage alternative algorithm are developed for solving the formulated problems. The optimal selection scheme decides whether users choose to locally compute or ofﬂoad computation tasks to the UAV.

2:00 pm – 4:30 pm: Understanding the 5G-air-simulator: A tutorial on design criteria, technical components, and reference use cases
Giuseppe Piro and Sergio Martiradonna, Politecnico di Bari
Abstract and covered topics: The 5G air interface, also known as New Radio, is providing a significant transformation in the mobile network landscape. It introduces flexible and heterogeneous capabilities to harmoniously blend numerous technical components since a variety of advanced services are being developed, each one entailing different requirements. Nonetheless, the effective management of such a broad diversity is a challenging task to accomplish.
As is well known, computer simulations are relentlessly engaged in the pursuit of existing research questions on how to design, evaluate, and optimize emerging communication technologies. In this context, the 5G-air-simulator aims to represent a significant step forward for the 5G simulation tools scene.
In particular, 5G-air-simulator is an open-source and event-driven tool modeling the key elements of the 5G air interface from a system-level perspective. It implements several network architectures with multiple cells and users, different mobility and application models, a calibrated link-to-system model for physical and data-link layers, and a wide range of features standardized for both control and user planes, as well as a set of technical components recently designed for the 5G air interface (such as massive Multiple Input Multiple Output, extended multicast and broadcast transmission schemes, predictor antennas, enhanced random access procedure, and NB-IoT). Moreover, it allows a flexible configuration, arrangement, and extension of its capabilities to model both new scenarios and new technical components, hence supporting advanced studies willing to address the research questions emerging from the deployment of current and upcoming mobile systems.
This tutorial will first present 5G-air-simulator and its general-purpose features. Then it will describe a series of simulation campaigns for typical 5G scenarios, recently investigated in scientific literature and European projects. Moreover, it will explain the syntax used to perform some simulations, as well as the steps to extract the main KPIs, in order to facilitate an immediate usage of 5G-air-simulator.
