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.

Downlink physical channels and signals

NR defines a similar set of physical channels to Long-Term Evolution (LTE). We already covered the PSS, SSS, and PBCH. In this section, we will cover the Physical Downlink Control Channel (PDCCH), the Physical Downlink Shared Channel (PDSCH), as well as the Channel State Information Reference Signal (CSI-RS). The Tracking Reference Signal (TRS) and Phase Tracking Reference Signal (PTRS) are new reference signals that have been introduced in NR – we will see what they are used for. Let’s learn about the PDCCH.

The PDCCH

In NR, the PDCCH carries the Downlink Control Information (DCI), like LTE. The modulation used for the channel is Quadrature Phase Shift Keying (QPSK) and the Radio Network Temporary Identifier (RNTI) masks the DCI Cyclic Redundancy Check (CRC) bits as it was done in LTE.

The PDCCH is divided into Control Channel Elements (CCEs) in NR. Each CCE is composed of six Resource Element Groups (REGs), where each...
