Continental, Ericsson, Nissan, NTT DoCoMo, OKI and Qualcomm Technologies have announced plans to carry out their first Cellular Vehicle-to-Everything (C-V2X) trials in Japan to validate the technology and demonstrate its benefits.

The trials are designed to show the enhanced range, reliability and latency benefits of C-V2X direct communications operating in 5-GHz band. Additionally, the C-V2X trials aim to demonstrate the complementary benefits of network-based communications utilizing LTE-Advanced (LTE-A).

The trial results are expected to help develop the ecosystem by providing inputs to the relevant stakeholders, including ITS-related organizations and government agencies, in preparation for the future of connected cars and the industry’s evolution towards 5G NR.

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 leverages 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.

The trial expected to begin later this year. 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 utilize the Qualcomm C-V2X reference design, which features the Qualcomm 9150 C-V2X chipset with integrated 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 KPIs for C-V2X technology validation.

OKI will bring their expertise in roadside unit (RSU) infrastructure and applications to demonstrate V2I as a viable technology for advanced traffic applications by integrating the 9150 chipset into their RSU.

Ericsson will join to 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.

“The C-V2X solution is unique in that it, within a common technology and ecosystem, offers both network-based and direct communication for V2X services,” said Erik Ekudden, chief technology officer at Ericsson. “With the network-based communication, there is a possibility to provide traffic safety and traffic efficiency services utilizing already existing coverage and penetration of cellular modems and smartphones. It also provides connectivity to various cloud-based services, providing a range of applications and value-added services.”

“This project will set a clear path toward connected cars and roads of the future that materialize the power of C-V2X,” said Hiroshi Nakamura, Chief Technology Officer at NTT DoCoMo.
