A consortium comprising Continental, Ericsson, Nissan, NTT DOCOMO, OKI, and Qualcomm Technologies has announced plans to carry out its first cellular vehicle-to-everything (C-V2X) trials in Japan.
The objective of the project is to validate and demonstrate the benefits of C-V2X using direct communication technology defined by the 3rd Generation Partnership Project (3GPP) in its Release 14 specifications. The trials are designed to show the enhanced range, reliability and latency benefits of C-V2X direct communications operated in the 5GHz waveband. The C-V2X Trials are also designed to demonstrate the complementary benefits of network-based communications using LTE-Advanced (LTE-A).
The trial results will help develop the ecosystem by providing inputs to the relevant stakeholders, including ITS-related organizations and government agencies, as they prepare for the future widespread deployment of connected and autonomous vehicles (CAVs), and the industry’s evolutionary transition toward 5G New Radio (NR), the new global cellular standard being defined in 3GPP.
While complementing other advanced driver assistance system (ADAS) sensors, such as radar, lidar, and camera systems, C-V2X provides non-line-of-sight (NLOS) low latency awareness with longer range and cloud capabilities, and is designed to extend a vehicle’s ability to see, hear and communicate further down the road, even at blind intersections.
C-V2X radio technology is state-of-the-art cellular technology and is being validated for global deployments, and makes use of the upper layer protocols developed by the automotive industry over years of research to support new advanced end-to-end use cases. C-V2X direct communications provides enhanced range and reliability without relying on cellular network assistance or coverage.
Preparation work is well underway, with the trial expected to begin in 2018, and the use-cases are designed to focus on vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) and vehicle-to-pedestrian (V2P) direct communications, as well as vehicle-to-network (V2N) operations over cellular network-based wide-area communications with cloud access.
For the field trials:
• Continental will use the Qualcomm C-V2X Reference Design, which features the 9150 C-V2X chipset with integrated Global Navigation Satellite System (GNSS) capability to build connected car systems and integrate the systems into Nissan vehicles.
• Nissan will perform V2X use-case selection and develop test scenarios with key performance indicators (KPIs) for C-V2X technology validation.
• ITS company OKI will bring its expertise in roadside unit (RSU) infrastructure and applications to demonstrate V2I as a viable technology for advanced traffic applications by integrating the Qualcomm 9150 C-V2X chipset into its devices.
• Telecoms company Ericsson will join the V2N use-case discussion considering combination of direct communication and LTE-A network technologies.
• NTT DOCOMO will provide LTE-A network and V2N applications to demonstrate the benefits of complementary use of network-based communications for a variety of advanced automotive informational safety use cases.
