China Mobile and Qualcomm have partnered to develop new roadside units (RSUs) for LTE-V2X communication based on the Qualcomm 9150 C-V2X chipset solution.
The new RSUs are co-developed by China Mobile Research Institute and China Mobile IoT (CMIoT) Company, a wholly-owned subsidiary of China Mobile.
Also referred to as C-V2X PC5 direct communication, LTE-V2X is a core technology of the Intelligent Transport System (ITS), which has received strong support from national policies in China, said Qualcomm. With its strong evolutionary path towards 5G New Radio (5G NR), LTE-V2X is a global solution for V2X communications designed to support improved automotive safety, automated driving and traffic efficiency, and is currently the only V2X communication technology compliant with the global 3GPP specifications.
The PC5-based direct communication mode of LTE-V2X offers vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) and vehicle-to-pedestrian (V2P) communications on the unified 5.9 GHz ITS bands without the need for a Subscriber Identity Module (SIM), cellular subscription or network assistance. Utilizing LTE-V2X in vehicles and in RSUs, vehicles on the road will have the capability to directly communicate with RSUs, allowing drivers to obtain information from RSUs in a variety of use cases such as traffic signal phase timing, quickly and efficiently.
Last month, Qualcomm Technologies and China's Datang Telecom announced the first successful multi-chipset vendor interoperability of C-V2X radio technology based on 3GPP R14 specs, in Beijing.
