China Mobile Research Institute, China Mobile IoT (CMIoT) and Qualcomm Technologies have announced new roadside units (RSUs) for LTE-V2X direct communication (PC5) based on Qualcomm’s 9150 C-V2X chipset solution.

Developed by CMIoT and China Mobile Research Institute, the new RSUs are based on 3GPP Release 14 standards and support an evolutionary path towards 5G NR.

Chenguang Wei, deputy general manager of China Mobile Research Institute, said the RSUs were developed with CMIoT deployed as a part of a pilot project in Wuxi, Jiangsu province.

LTE-V2X (also known as C-V2X) is a core technology of the intelligent transport system (ITS), which is designed to support improved automotive safety, automated driving and traffic efficiency,

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 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.

C-V2X is supported by the 5G Automotive Association (5GAA), which is driving C-V2X trials to ensure the technology is ready for commercial deployment as early as 2019.
