MORNING SESSION -  5G New Radio simulations with ns-3 

Abstract and covered topics:  This tutorial is designed as an introduction to the 5G New Radio modules of ns-3.  By the end of the session, participants should have a basic understanding of the scope of the 5G New Radio module in ns-3, and of the capability that the module and its branches can offer.

The following elements are planned to be covered: 

• Basics of 3GPP NR at PHY and MAC
• Evolution across releases
• NR model overview & architecture
• Modeling assumptions
• Channel model and antenna models
• NR Radio Protocol Stack model
• PHY model
• MAC models
• MAC Scheduler models
• RLC and PDCP protocol models
• RRC model
• Other branches


AFTERNOON SESSION - Understanding the 5G-air-simulator: A tutorial on design criteria, technical components, and reference use cases

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.

Short bio:

Lorenza Giupponi is a Telecom engineer from University of Rome “La Sapienza” (2002) and a PhD from Technical University of Catalonia (UPC) (2007). She joined the Radio Communications Group of UPC in 2003 with a fellowship of the Spanish Ministry of Education. During 2006 and 2007 she was assistant professor in UPC. 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.).

Biljana Bojovic received Electrical and Computer Engineering degree from the Faculty of Technical Sciences at the University of Novi Sad in June 2008. In January 2007, she joined Schneider Electric DMS (Novi Sad, Serbia), as an internship student and later as a software engineer working on an integration of smart grid systems in close collaboration with Siemens (Minneapolis, Minnesota). In September 2009, she joined CTTC to pursue her Ph.D. on Machine Learning Techniques for Cognitive Wireless Networking following the Ph.D. program at the Networking Engineering Department at the Polytechnic University of Catalonia, Barcelona. During the spring semester 2013, she was a visiting Ph.D. student at the Qualcomm Institute at the University of California, San Diego. Since August 2015 she has been working as a research engineer at the Mobile Networks Department at CTTC and was involved in different industrial research projects focusing on 4G and 5G technologies for unlicensed spectrum, i.e., LAA, LTE-U, and NR-U. She is developer and maintainer of LTE and NR modules of the ns-3 network simulator. ​
