5G NR: Architecture, Technology, Implementation, and Operation of 3GPP New Radio Standards is an in-depth, systematic, technical reference on 3GPP’s New Radio standards (Release 15 and beyond), covering the underlying theory, functional descriptions, practical considerations, and implementation of the 5G new radio access technology. The book describes the design and operation of individual components and shows how they are integrated into the overall system and operate from a system’s perspective. Uniquely, this book gives detailed information on RAN protocol layers, transports, network architectures, and services, as well as practical implementation and deployment issues, making it suitable for researchers and engineers who are designing and developing 5G systems.

Reflecting on the author's 30 plus years of experience in signal processing, microelectronics, and wireless communication system design, this book is ideal for professional engineers, researchers, and graduate students who are working and researching in cellular communication systems and protocols as well as mobile broadband wireless standards.

Key Features

  • Features strong focus on practical considerations, implementation, and deployment issues

  • Takes a top-down approach to explain system operation and functional interconnection
  • Covers all functional components, features, and interfaces based on clear protocol structure and block diagrams
  • Describes RF and transceiver design considerations in sub-6 GHz and mmWave bands
  • Covers network slicing, SDN/NFV/MEC networks and cloud, and virtualized RAN architectures

  • Comprehensive coverage of NR multiantenna techniques and beamformed operation

A consistent and integrated coverage reflecting the author’s decades of experience in developing 3G, 4G, and 5G technologies and writing two successful books in these areas


R&D engineers working in cellular communication systems, radio air-interface technologies, cellular telecommunication protocols, advanced radio access technologies for 4G/5G systems, or broadband cellular standards. Postgraduate students and university researchers in mobile and wireless communications
