5GAA: Visionary Roadmap for Advanced Driving Use Cases, Connectivity Technologies, and Radio Spectrum Needs
This 5G Automotive Association (5GAA) white paper presents the results of its studies relating to the evolution of automotive connectivity for the purposes of enhanced road safety, improved traffic efficiency, greener environmental impact, and more comfortable driving.
The most promising advanced driving use cases are:
- Cooperative Manoeuvres and Sensor Sharing.
- Cellular Vehicle-To-Everything (C-V2X) standards as well as availability of required technologies and devices, i.e. on-board units (OBUs), road-side units (RSUs), and smartphones, integrating the latest chipsets and modules. The market trajectory of the identified use cases is described along with the expected timeline for their mass market deployment.
The white paper also highlights the spectrum needs for basic and advanced driving use cases. For direct communication, this corresponds to between 10 and 20 MHz at 5.9 GHz for basic safety, and an additional 40 MHz or more at 5.9 GHz for advanced driving.
The market trajectory of the identified use cases is described along with the expected timeline for their mass market deployment.
On standards, the white paper notes that the communication layers specified in 3GPP describe the radio communication capabilities and functionalities of C-V2X. Industry continues to develop the upper layers for the support of various use cases by standardisation bodies such as ETSI, SAE, C-SAE, and ISO. These profiles and protocols are then being implemented in end-to-end systems to enable ITS use cases. However, work on the upper layers is often region-specific, taking into account applicable considerations and regulations.
