The fifth generation (5G) of cellular communication networks marks a significant leap in wireless technology, promising higher data rates, ultra-low latency, and massive device connectivity. As with any technological leap, a deep and intuitive understanding of the underlying principles and system-level trade-offs is essential not only for researchers and engineers but also for students and practitioners working to shape the future of wireless communications. This book, Understanding 5G New Radio: An Experimental Approach, is a product of our experience in academia and industry, and aims to bridge the gap between theory and practice. It offers a unique hands-on approach to understanding 5G New Radio (NR), the global standard for a unified, more capable 5G wireless air interface. Instead of treating 5G purely as a theoretical subject or as a collection of standards documents, we adopt an experimental methodology using the NetSim simulation platform. Each chapter is structured to first build the necessary theoretical foundation and then validate the concepts through carefully designed simulation experiments. This duallayered approach not only reinforces conceptual clarity but also exposes the reader to the complexities of real-world system behavior. The content spans a wide range of topics fundamental to 5G NR, including MIMO beamforming, pathloss modeling, transport block processing, OFDM numerology, interference and handover modeling, scheduler performance, and massive MIMO. Wherever possible, we emphasize the connection between abstract ideas and their practical implications in system design and performance. To support this hands-on understanding, readers who purchase this book are eligible for a free NetSim license, enabling access to the simulation exercises used throughout the text. An executable version of NetSim v13.3 and the associated experiment configuration files required to execute all the experiments in this book can be found online at https://tetcos.com/5G-Book.html. This book is intended for graduate students, researchers, educators, and industry professionals interested in 5G NR and wireless systems. While a background in wireless communication principles will aid in comprehension, the book is designed to be accessible to those with varied levels of expertise, particularly through the progressive deepening of concepts.
