Testing C-V2X access layer for ITS devices

May 5, 2020

In January 2020, ETSI published EN 303 613 - defining the use of C-V2X as an access layer technology for Intelligent Transportation Systems (ITS) in the 5 GHz frequency band. At the same time, ETSI has also updated other ITS protocols above the access layer - in ETSI TR 101 607 - to further support LTE-V2X for all Cooperative-Intelligent Transport System scenarios. 

Now, ETSI and the 5GAA are planning for their second “Cellular-Vehicle-to-Everything” (C-V2X) Plugtests* event - to test against these specifications.

Held remotely, between July 20 to 31, the event will leverage the ETSI Hub for Interoperability and Validation (HIVE) - connecting the participants’ labs for multi-party testing. The C-V2X Plugtests will focus on testing ITS security features and will allow C-V2X device vendors and Public Key Infrastructure (PKI) vendors to run test sessions and also validate their common understanding of the standards.

Progress in TSG SA (Post SA#87-e)

April 27, 2020

During his recent webinar, TSG SA Chair, Georg Mayer described the effects of the COVID-19 pandemic on the 3GPP schedule. He also gave an update on the latest 3GPP releases and made a commitment to bring in further initiatives for new experts, to make 3GPP more approachable in the future.

On e-meetings replacing physical meetings, Georg Mayer observed that it is “likely that the crisis will mean that we will have to cancel more F2F meetings in Q3 and even Q4.” He noted that the resumption of the F2F meeting cycle is not just dependent on the virus being defeated; It will take time for Government and company travel restrictions to be lifted. He concluded; “As a global organization, we are dependent that people from all corners of the world can participate - and in the current situation this is very challenging”.

On a positive note, he reported that e-meetings have gone very well and that Release 16 is set to be completed at the end of June 2020. He explained the significance of the extra three months taken for the Rel-16 functional freeze, now scheduled to coincide with end of the ASN.1 and API coding phase. By doing that, the 3GPP groups can complete the release in time for a critical 5G deadline, as the due date falls for 3GPP’s submission to the ITU IMT-2020 process.

RAN work progressing beyond eMBB

April 24, 2020

In our recent webinar on 5G radio standards, TSG RAN Chair - Balazs Bertenyi shared his thoughts about the status of Release 16 and Release 17 specifications.

Since the beginning of the year e-meetings have replaced 3GPP face-to-face group meetings. Despite the physical limitations of that way of working, he observed that the commitment of the experts is as strong as ever and that the technical work is proceeding well.

Feedback from TSG CT#87-e

April 21, 2020

After the dust had settled on the latest TSG Plenary meetings, we held three webinars - recorded on April 9 – to get the leadership’s thoughts on what each meeting achieved.

In our first webinar, Lionel Morand takes us through the responsibilities of the Core network and terminals (CT) group, focusing on the priority given to getting Release 16 features done by June (TSG#88).

He describes TSG CT as the 3GPP factory for transforming service functional requirements into network enablers, via the group’s protocol specifications. 

During the webinar, Lionel Morand discusses user plane and control plane evolution, emphasising the new work done on the control plane; with the service based architecture replacing node management with services that can be discovered by any function at the control level. This allows very flexible deployments and the introduction of new functionality via a virtualized and cloud friendly network.

The webinar concluded with a look at the role of CT in completing Release 16, with over 50 CT level work items to finish by the end of TSG CT#88-e meeting, starting on June 29. 

Changing 3GPP to help the verticals

February 25, 2020

Our latest video, recorded at TSG#86 in Sitges, December 2019, brings together:

  • Joachim Walewski, Siemens
  • Roland Beutler, EBU
  • Nicolas Chuberre, Thales Alenia Space
  • Georg Mayer, 3GPP SA Chair.

They discuss the reasons why their sector is in 3GPP and how they feel it is going. There are some frank views on the difficulties encountered and the frustrations that still persist, but there are also some clues on how new verticals don't have to start from scratch and how the project is making attempts to learn from the experience of adapting to the needs of the verticals.
