Companies gear up for C-V2X validation trials in Japan


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.
