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.

Physical channels and signals for the initial access procedure

We have covered the general aspects of the initial access procedure. In this section, we will be discussing the details of how the SS blocks and the PRACH are defined. The channels that define SS block are the Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS), and they are placed at the PBCH. These downlink signals are the only ones that are periodically transmitted in NR. Note that they can be turned off by the network thanks to NR’s ultra-lean design.

As we emphasized, coexistence and forward compatibility with LTE are crucial for NR. To achieve this, it is necessary to have as few blocked resources as possible. So, even though SS block transmission is periodic, having the option to turn off certain SS block locations or opportunities will help the network avoid interference with LTE or other featured services.
