When user equipment (UE) changes its serving mobile network (e.g. when crossing country borders), an interruption in connectivity can occur as the UE needs to connect to a new network which takes some time, i.e. scanning for a public land mobile network that it can attempt to use or ‘visit’ (hence VPLMN).
These interruptions can often result in disconnected phone calls and/or blackout periods for connected vehicle services lasting up to several minutes. This report seeks to look at this problem and examine the potential solutions available.

Cellular vehicle-to-everything, or C-V2X, allows vehicles to communicate with each other and everything around them.
The technology is based on the same radio technologies used for mobile networks around the world and standardised by 3GPP, the global standardisation organisation for all mobile networks.

Millions of vehicles are already connected today.
Discover more about C-V2X on the video below.

 

This report presents the results of the 5GAA work item Use Case Implementation Description.
Use cases examined include Cross-Traffic Left-Turn Assist (LTA), Emergency Brake Warning and Traffic Jam Warning and Route Information. The UCIDs in this Report provide a first step to achieving greater information-sharing between actors by bringing together existing pieces (specifications, profiles, interface descriptions, etc.). Likewise, the descriptions provide guidance on how to leverage the benefits of combining C-V2X’s multiple communication paths in order to realise the use cases.

This STiCAD work item seeks to determine, propose and evaluate possibilities for telecommunication operators, vendors, and any further identified stakeholders to provide what is necessary in order to enable the car OEM to better treat safety for systems that exist beyond a single-vehicle. To achieve this, it was decided to find representative safety requirements for two selected use cases that cover the V2X scenarios of direct communication and network-based information delivery.

This White Paper outlines five non-mutually exclusive options for ecosystem cooperation models relevant to 5G CAM (Connected and Automated Mobility) infrastructure deployment and use. 5GAA believes these options may bring even more benefits when combined. Building upon this first assessment, 5GAA considers that in the context of the large-scale introduction of advanced safety and automated driving use cases supported by C-V2X, a more integrated model involving all parties (vehicle manufacturers, road operators, communication service providers i.e. mobile network operators and neutral host infrastructure providers) should be considered as well as other services providers who will play an increasing role in the ecosystem e.g., location-based data marketplace, Mobility as a Service (MaaS), etc.

Edge Computing is an important topic in Vehicle-to-Everything (V2X) use cases, as many such cases ultimately require guarantees of low latency and high reliability. The use cases involve a large amount of regional data which needs to be processed and dispatched locally instead of being uploaded over the internet to its cloud services which, at scale, becomes time- and cost-intensive without generating much-added value. The present document includes architecture and deployment models in the event that Edge Computing is used for these V2X use cases and also describes how interoperability and service continuity can be solved.

Together with relevant ecosystem actors in China – from Government officials to telecom and automaker companies and the association’s community – the 5G Automotive Association (5GAA) has presented the latest developments on Cellular Vehicle-to-Everything applications and services at GSMA’s Mobile World Congress Shanghai 2021.

The present document aims to study the requirements of positioning, build understanding of the positioning system framework, and offer the corresponding technologies according to the requirements and environments, as well as some demonstrations in High-Accuracy Positioning for Vehicle-to-Everything (V2XHAP) services.

With the evolution of V2X services from assisted driving to automated driving, the use case requirements are also changing in terms of the availability of network coverage, level of uncertainty, availability of features for simultaneous localisation and mapping (SLAM)-based positioning techniques, reliability, latency, speed, data rate, communication range, as well as positioning accuracy, which is changing from metre level to sub-metre level. Different from other services, positioning information is one of the essentials to guarantee the safety of Internet of Vehicles (IoV). Some important KPIs for positioning have been described in 3GPP, such as positioning accuracy, latency, update rate, power consumption, etc. Furthermore, there are some specific needs in terms of V2X service scenarios, such as continuity, reliability, and security/privacy, etc. All positioning KPIs for V2X mentioned above need to be clarified, especially positioning accuracy which is the most basic requirement in V2X service.  In some use cases, such as automated driving, remote driving and platooning, centimetre-level positioning with stable performance provides the necessary accuracy and safety assurance.

Following the first volume (Volume I) set of Use Case descriptions (previously named as ‘WAVE 1’) and the corresponding framework developed in WG1, this document presents the second volume of Use Case descriptions (previously named as ‘WAVE 2’). One of the goals with this second set is to describe advanced Use Cases that have challenging requirements for future communication systems, such as 5G – as reflected in the report title.

The Use Case descriptions are written from the vehicle perspective and strive to be solution agnostic and applicable to both driven and autonomous vehicles. The realisation of Use Cases does not preclude applications performing various tasks supporting the Use Cases, such as collecting information, analysing etc.

After last year’s cancellation, 5GAA is happy to bring again a Partner Programme to MWC Shanghai 2021 on Wednesday, 24 February, 9.30 AM-12.30 PM (CST).

Smart mobility technology is already here. C-V2X technology now allows connected vehicles to communicate with the cloud, directly with each other and with their surroundings. Thanks to 4G LTE cellular technology, as well as the emerging 5th generation of high speed and low latency communications, 5G, traffic will be optimised, and emissions will be reduced. Prominent members  will update you on how C-V2X fuels the automotive connected revolution, with a comprehensive overview of its latest development in China including the valuable perspective of Chinese regulators.

Further information will be shared shortly!
