Overview of this book

We are living in an era where ultra-fast internet speed is not a want, but a necessity. As applications continue to evolve, they demand a reliable network with low latency and high speed. With the widespread commercial adoption of driverless cars, robotic factory floors, and AR/VR-based immersive sporting events, speed and reliability are becoming more crucial than ever before. Fortunately, the power of 5G technology enables all this and much more. This book helps you understand the fundamental building blocks that enable 5G technology. You’ll explore the unique aspects that make 5G capable of meeting high-quality demands, including technologies that back 5G, enhancements in the air interface, and packet core, which come together to create a network with unparalleled performance. As you advance, you’ll discover how to design and implement both 5G macro and private networks, while also learning about the various design and deployment options available and which option is best suited for specific use cases. After that, you’ll check out the operational and maintenance aspects of such networks and how 5G works together with fixed wireline and satellite technologies. By the end of this book, you’ll understand the theoretical and practical aspects of 5G, enabling you to use it as a handbook to establish a 5G network.

Summary

In this chapter, we introduced you to NR general physical layer procedures and channel structure. We made comparisons of bandwidths, energy efficiency, and spectral efficiency between LTE and NR.

Then, we covered all the important aspects regarding the NR waveform, numerology, and frame structure. We learned that NR is OFDM-based with scalable subcarrier spacing. This changes the slot durations to allow for different kinds of services, but it also presents challenges regarding how these different subcarrier spacings can be multiplexed in the frequency domain without interfering between them. We have also discovered that NR supports a slot-based scheduling mode. We saw that there are several interesting use cases that necessitate the introduction of this scheduling mode, such as LTE/NR coexistence or forward compatibility. Finally, we have described the dynamic TDD duplexing mode that NR introduces and how it is signaled to devices by using the slot format indication.
