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.

BWPs

In this last section of this chapter, we will cover another concept introduced in NR, which is the BWPs. This concept is new in NR and very powerful for a few interesting and important use cases.

In this section, we will learn what BWPs are and how they are configured, activated, and deactivated. We will also describe the main use cases for BWPs to better understand their importance in the NR physical layer.

Defining a BWP

So, let’s start by defining what a BWP is. A BWP is a set of contiguous PRBs with nested bandwidths where the devices are only allowed to transmit or receive. Each BWP has its own configuration with a specific numerology to use and a set of reserved resources for which transmission is not allowed. Devices always operate using BWPs. This means that at least one initial BWP must be defined by the PBCH so that all devices can access it. This initial BWP will also contain the CORESET and PDSCH for the RMSI. However, a BWP does not need to contain...
