5G NR – The Next Generation Wireless Access Technology; The Next Generation Wireless Access Technology follows the authors highly celebrated books on 3G and 4G by providing a new level of insight into 5G NR. After an initial discussion of the background to 5G, including requirements, spectrum aspects and the standardization timeline, all technology features of the first phase of NR are described in detail.
Included is a detailed description of the NR physical-layer structure and higher-layer protocols, RF and spectrum aspects and co-existence and interworking with LTE. The book is provides a good understanding of NR and the different NR technology components, giving insight into why a certain solution was selected.
- Key radio-related requirements of NR, design principles, technical features
- Details of basic NR transmission structure, showing where it has been inherited from LTE and where it deviates from it, and the reasons why
- NR Multi-antenna transmission functionality
- Detailed description of the signals and functionality of the initial NR access, including signals for synchronization and system information, random access and paging
- LTE/NR co-existence in the same spectrum, the benefits of their interworking as one system
- The different aspects of mobility in NR RF requirements for NR will be described both for BS and UE, both for the legacy bands and for the new mm-wave bands
All three authors of this book work at Ericsson Research and have been deeply involved in 3G and 4G development and standardization. They are leading experts in the field and are actively contributing to the standardization of 5G within 3GPP.
- Gives a concise and accessible explanation of the underlying technology and standards for 5G NR radio-access technology
- Provides detailed description of the NR physical-layer structure and higher-layer protocols, RF and spectrum aspects and co-existence and interworking with LTE
- Gives insight not only into the details of the NR specification but also an understanding of why certain solutions look like they do

- What is 5G?
This will be an introductory text outlining what 5G is and what we do it.
It will put 5G in its context vs. earlier generations
- 1G/2G: Mobile telephony
- 3G/4G: Mobile broadband
- 5G: providing connectivity for anyone and anything, i.e. 5G is much more than just further enhanced mobile broadband
It will discuss the requirements of 5G
- Higher data rates and higher capacity
- Much lower latency
- Extreme reliability
It will discuss how many of the new 5G requirements can and will be provided by the evolution of LTE. Thus the evolution of LTE is one important component of 5G. However, it will also describe why a new 5G radio-access technology is also needed and this new 5G radio-access technology (NR) is the main focus of this book.
This text will discuss the different fora where 5G wireless access is discussed and the procedures and time plans of these discussions/activities. Main focus will be on ITU and 3GPP:
The text will describe the ITU activities of 5G (IMT-2020) and put that into the context of the overall ITU activities on IMT
- IMT-2000 (3G)
- IMT-Advanced (4G)
- IMT-2020 (5G)
It will discuss the ITU requirements for IMT-2020 and relate these to the more general usage-driven requirements on 5G discussed in the previous chapter. Finally it will describe the ITU time plan and process for IMT-2020 and how it relates to standardisation.
The text will then discuss, on a non-technical level, the 3GPP activities on 5G especially on the time plans and how these relate to the ITU time plan for IMT-2020 as well as other factors. This will include the activities on the evolution. However, the main focus will be on the 3GPP activities for the new 5G radio-access technology (NR).
