5G NR: The Next Generation Wireless Access

OFDM, ultra-lean, mini-slots, beam-centric, …. these are just some of the many words and acronyms being used in conjunction with 5G and it is easy to get lost among all the terms and technology components. We believe our recently released book 5G NR: The Next Generation Wireless Access Technology, fills an important need for those interested in the recently released 5G NR standard. The book describes the standard in detail, both the technologies as such but also why specific technologies were decided to be included in the standard.

For many years we have actively participated in the 3GPP standardization representing Ericsson, the largest contributor to 3GPP. Given the complexity of the 3GPP standardization process – the number of documents sent in to just one of the 3GPP working groups is around two and a half times what Shakespeare wrote in his entire life – reading the specifications and the contributions can be quite challenging. This is where we see the role of our book – to explain NR and to give insight in why a certain solution was selected.

The structure and style-of-writing of this brand-new book should be familiar to anyone who has read our previous books on HSPA and LTE. 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.

To celebrate the release of the book, we wore specially designed T-shirts at a recent 3GPP meeting as shown in the picture. Interestingly, many people wanted to buy not only the book but also the t-shirt!

Just the other day we got the coffee mugs as well!

The book can be ordered at Elsevier and at major bookstores.

Erik Dahlman

Dr. Erik Dahlman is a Senior Expert in Radio Access Technologies within Ericsson Research. He has been deeply involved in the development and standardization of 3G radio access technologies (WCDMA and HSPA) and 4G (LTE) and its continued evolution. Currently he is active in the standardization and development of the 5G wireless access technologies, with special focus on the evolution of 5G. Erik Dahlman is the co-author of the books 3G Evolution – HSPA and LTE for Mobile Broadband, 4G – LTE and LTE-Advanced for mobile broadband, 4G – LTE-Advanced Pro and The Road to 5G and, most recently, 5G NR – The Next Generation Wireless Access Technology. In 2009, Erik Dahlman received the Swedish Government Major Technical Award for his contributions to the success of HSPA. In 2010, he was part of the Ericsson team receiving the LTE Award for “Best Contribution to LTE Standards”, and in 2014 he was nominated for the European Inventor Award, the most prestigious inventor award in Europe, for contributions to LTE.
