Research, insights and technology reflections

Stefan Parkvall

Stefan Parkvall is a Principal Researcher at Ericsson Research working with 5G and future radio access. He is one of the key persons in the development of HSPA, LTE and NR radio access and has been deeply involved in 3GPP standardization for many years. Dr Parkvall is a fellow of the IEEE and served as an IEEE Distinguished lecturer 2011-2012. He is co-author of the popular books “3G Evolution – HSPA and LTE for Mobile Broadband”, “HSPA evolution – the Fundamentals for Mobile Broadband”, “4G – LTE/LTE-Advanced for Mobile Broadband”, “4G, LTE Advanced Pro and the Road to 5G”, and “5G NR – The Next Generation Wireless Access”. Dr. Parkvall has more than 1000 patents in the area of mobile communication. In 2005, he received the Ericsson "Inventor of the Year" award, in 2009 the Swedish government’s Major Technical Award for contributions to the success of HSPA, and in 2014 he and Ericsson colleagues were among the finalists for the European Inventor Award for their contributions to LTE. Dr Parkvall holds a Ph.D. in electrical engineering from the Royal Institute of Technology (KTH) in Stockholm, Sweden. Previous positions include assistant professor in communication theory at KTH, and visiting researcher at University of California, San Diego, USA.

5G NR release 16 – start of the 5G Evolution

The finalization of the 3GPP release 15 in June this year was a major milestone in many respects. The first 5G New Radio (NR) specifications are complete and commercial deployments will be available by the end of this year. It is also the basis for the continuous evolution of 5G NR technology, spanning across multiple releases, to further improve performance and address new use cases. The first step of this evolution was recently taken when several 3GPP working groups met in Gothenburg, Sweden, to start the work on release 16.

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.

5 tech trends you need to know about

Being an engineer has probably never been more interesting than it is today, with such rapid advances in technology and how this impacts both our daily life and our work at Ericsson. New devices, inventions, solutions, and tools appear every day alongside the ongoing digitization of all kinds of industries.
It’s hard for anyone to be updated, but to help, our CTO, Erik Ekudden, has just published a new article examining what he sees as the five most significant trends in technology evolution.

Inspired by his list, I have some personal reflections on technology evolution.

How do you create a new ‘G’? Like 5G

Have you ever thought about how a new ‘G’ is created?

5G is the next generation in mobile communications, addressing a wide range of use cases. An integral part of 5G is today’s 4G, and, therefore, those at the forefront of 4G technologies are also more likely to lead the introduction of 5G. This is certainly true of Ericsson – we’ve taken the lead in creating previous generations of technology, and our patent portfolio covers 2G, 3G and 4G. Now, through a continuation of our pioneering research and technology development, we’re ready to advance business and society in more innovative ways than ever before, with the introduction of 5G.

5G now started in 3GPP

Work on next-generation wireless access, commonly referred to as 5G, has officially started in 3GPP with the 5G workshop – attended by a record number of 500 technical leaders. The workshop was held in conjunction with the RAN plenary in Phoenix, AZ, USA, where a study item on channel modelling for frequencies up to 100 GHz was approved.

In this blog post I will share some reflections on the workshop.

Release 14 – the start of 5G standardization

Release 14 will mark the start of 5G work in 3GPP. In addition to the continued LTE evolution, a new radio access technology will be standardized, and these two technologies together will form 5G radio access. In this blog post, I will shed some light on a number of the key areas – low latency communication, spectrum flexibility, machine type communication, multi-antenna and multi-site transmission techniques, and ultra-lean design – and how they can be part of the upcoming 5G work in 3GPP.
