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.

Channel coding schemes

Low-Density Parity Check (LDPC) code is used for eMBB physical data channels in which polar codes are employed for eMBB physical control channels, as well as for the PBCH. These channel coding schemes provide better throughput and latency performance compared to what we have in legacy LTE. Note that channel coding for other use cases such as massive Machine Type Communications (mMTC) and Ultra-Reliable Low Latency Communications (URLLC) are not part of Release 15’s scope. So, let’s start.

Transport channel coding chains

The following figure represents the basic coding scheme for the downlink shared channel. The diagram is very similar to what we have in LTE. A CRC is attached to the transport block, it is segmented onto the code blocks, and then, additional CRSes are attached to each code block:

Then, LDPC coding is performed for each...
