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.
