Interoperability and compatibility of 5G specifications

November 27, 2018

By the 3GPP RAN and RAN WG Chairs

Following the freeze of 5G Non-Standalone (NSA) specifications in March 2018 and 5G Standalone (SA) specifications in September 2018 3GPP has been continuing its efforts to ensure full functional integrity and interoperability of 5G NR specifications, especially in light of the imminent first deployments.

There has recently been a lot of industry interest in some of the corrections to the 5G NR specifications, on whether they are backwards compatible (BC) or non backwards compatible (NBC), and possible consequences for network deployment plans and chipset/device plans. Here is a summary from the 3GPP RAN and RAN WG Chairmen on how 5G NR corrections are being handled in 3GPP.

After completion of every release of the 3GPP specifications there is an ongoing process to fix “bugs” in the standards. The process uses Change Requests (CRs) submitted by member companies to the RAN working group meetings. CRs are discussed, often modified to address feedback from other companies, and then agreed or rejected. Four times a year the agreed CRs are approved by the TSG RAN plenary meetings and then included in the next version of the specifications.

3GPP Summit at CEATEC JAPAN 2018

November 1, 2018

3GPP and its Japanese Organizational Partners: The Telecommunication Technology Committee (TTC) and Association of Radio Industries and Businesses (ARIB) have hosted a “3GPP Summit” Conference Session at CEATEC JAPAN 2018, one of Japan’s largest ICT Conference and Exhibitions (https://www.ceatec.com/en/), on 17th October, 2018 in Makuhari area, Chiba-Pref., Japan.

This event was co-located with the “5G International Workshop” hosted by Japanese Ministry of Internal Affairs and Communications (MIC) and 5G Mobile Communications Promotion Forum (5GMF), in the same room that afternoon. 

The “3GPP Summit” featured all three Technical Specification Group (TSG) Chairman (CT, RAN, SA) alongside their Japanese Vice Chairman, all joined by the Chairman of the 3GPP Security group (SA3) and the 5G Automotive Association (5GAA) – a Partner in 3GPP – who were also presenting. The 3GPP technical leadership event attracted an audience of around 700 people, which was in excess of the full seating capacity of the largest conference room in the Makuhari Messe expo center (https://www.m-messe.co.jp/en/) – So it was standing room only!

20th Anniversary approaches for 3GPP

October 23, 2018

3GPP Working Group SA2 celebrated the 20th anniversary of 3GPP at their recent meeting – SA2#129, held in Dongguan China – by wearing a special commemorative pin (pictured here) and by attending a celebratory social event.

Yingtao Li, President of Products & Solutions at Huawei - who hosted the meeting – congratulated 3GPP on two decades of hard work and for remaining relevant to the success of the industry. He presented commemorative gifts to seven of the original 1999 - SA2 delegates, who are still active in the group, including the current SA2 Chairman, Frank Mademann.

3GPP 5G – Briefing for Evaluation Groups

October 27, 2018

This week’s 3GPP Workshop on 5G NR, hosted by the European Commission, has been a comprehensive briefing from the key experts in 3GPP for the benefit of the official Independent Evaluation Groups (IEGs), who’s job it will be to report to the International Telecommunications Union (ITU) on whether the 3GPP system for 5G meets the performance requirements (in ITU-R M.2412) for an IMT-2020 technology.


5G includes Virtual Reality from day 1!

October 4, 2018

By Frédéric Gabin, Gilles Teniou and Thomas Stockhammer

To help address the 5G Phase 1 service requirements for Virtual Reality (VR), the 3GPP Codec and Media Working Group (SA4) has completed work on the support of 360° VR streaming services, within Release-15 of the specifications.

Virtual Reality is the ability to be present in a space created by the rendering of natural or synthetic image and sound. To facilitate that presence a set of VR Video and Audio operating points and their mapping to Dynamic and Adaptive HTTP Streaming (DASH) have now been specified in 3GPP specification TS 26.118.

The specification is based on the definition of TV video profiles in 3GPP Release 14, but adds the extensions needed to enable VR services over the large range of device types envisaged for the market.
