5G New Radio (NR) Specs Approved

The 3GPP initiative officially approved the 5G New Radio (NR) specifications. Balazs Berenyi, 3GPP RAN Chair, described the approval as "an impressive achievement in a remarkably short time, with credit due particularly to the Working Groups."


At Mobile World Congress 2017 in February, major mobile network operators and vendors issued a call to accelerate the 5G New Radio (NR) standardization schedule to enable large-scale trials and deployments a year earlier than the previously expected timeline. Companies backing this accelerated schedule for 5G include AT&T, NTT DOCOMO, SK Telecom, Vodafone, Ericsson, Qualcomm, British Telecom, Telstra, Korea Telecom, Intel, LG Uplus, KDDI, LG Electronics, Telia, Swisscom, TIM, Etisalat Group, Huawei, Sprint, Vivo, ZTE and Deutsche Telekom.

The first 3GPP 5G NR specification will be part of Release 15 - the global 5G standard that will make use of both sub-6 GHz and mmWave spectrum bands.

"We view both the Non-Standalone and Standalone modes of New Radio as equally important for the completeness of the 5G standard specification. This timely finalization of NSA is one important step on that journey and in the development of the 5G ecosystem," said Bruno Jacobfeuerborn, CTO Deutsche Telekom. "It is crucial that the industry now redoubles its focus on the Standalone mode to achieve progress towards a full 5G system, so we can bring key 5G innovations such as network slicing to our customers."

"The first version of 5G NR not only provides a NSA solution for 5G deployment but also completes the common part of NSA and SA, which lay a solid foundation for a global unified 5G system with global market scale. We believe the next important milestone that is SA standard providing end to end 5G new capability could be completed by June of 2018, which is very crucial to enable the operators to explore the enterprise and vertical markets. China Mobile is actively working with industry partners for 5G commercialization in year of 2020 and providing various services to customer." said Zhengmao Li, EVP of China Mobile Group.

Erik Ekudden, CTO at Ericsson, said: "3GPP has done a tremendous job to complete the first 5G specifications according to industry demand and expectations. As a prime contributor to 5G standardization, Ericsson has worked with industry partners in the evolution of mobile technology to a global network platform for consumers and enterprises. Our research team has worked on 5G since 2010 including early 5G testbed efforts created together with these industry partners. The open contribution-driven specification work and the rapid completion of the first 5G standards for global deployment demonstrates the strength of the 5G eco-system."



In October 2016, Verizon, Qualcomm Technologies, and Novatel Wireless, confirmed plans to expedite the rollout of 5G New Radio (NR) millimeter wave (mmWave) technology.  The companies have agreed to collaborate on over-the-air field trials based on the 5G NR Release-15 specifications being developed by 3GPP, with hopes of moving the mobile ecosystem towards faster validation and commercialization of 5G NR mmWave technologies at scale before the end of the decade.

The expedited plan call for an initial focus on 5G NR operation in 28 GHz and 39 GHz mmWave spectrum bands. The goal is to achieve robust multi-gigabit per second data rates with mobility at significantly lower latencies than today’s networks. Over-the-air trials are expected starting in 2018, that will be compliant with the first 3GPP 5G NR specification that will be part of Release 15. The trials will utilize 5G NR mmWave mobile test platforms from Qualcomm and will employ advanced 5G NR Multiple-Input Multiple-Output (MIMO) antenna technology with adaptive beamforming and beam tracking techniques.

In September, Deutsche Telekom activated its first, pre-standard 5G connection over its commercial network in central Berlin using 3.7 GHz spectrum.The 5G connection is operating a over 2 Gbps with a low latency of three milliseconds.

Huawei supplied the user equipment based on 3GPP specifications for 5G New Radio (NR), the deployment on commercial sites is the first in Europe and marks an important advancement in the global development of 5G.
