This application Note is based on CMW500, SMBV100B and Vector CANoe.Car2x Software and guides to how to simulate the specific Cellular Vehicle-to-Everything (C-V2X) wireless environment in respect to road transport scenarios and transmitted messages around the Device Under Test (DUT) like a Telematics Control Unit (TCU). It shows how to verify and validate the C-V2X application of the DUT in laboratory environment. The virtual simulation scenario is not limited to the requirements of CSAE53-2017 specification, and it could be modified by user according to this operating guide with CANoe.Vehicle-to-everything (V2X) is a new generation of information and communications technologies that connect vehicles to everything. The objective of V2X is to increase road safety and manage traffic efficiently.C-V2X is designed to offer low-latency vehicle-to-vehicle (V2V), vehicle-to-roadside infrastructure (V2I) and vehicle-to-pedestrian (V2P) communications services to add a new dimension to future advanced driver assistance systems (ADAS). C-V2X as one communications standard defined by 3GPP in Release 14 uses LTE technology as the physical interface for communications. The standard describes two types of communications. The vehicle-to-network (V2N) communications type, exploits the cellular Uu interface, uses traditional cellular link to enable cloud services to be integrated into end-to-end solutions, e.g. to allow road and traffic information for a given area to be distributed to the vehicles.The second type is referred to as direct or PC5/Sidelink (V2V, V2I, V2P) communications, where data transmission takes place over the PC5 interface. In that type, C-V2X does not necessarily require a cellular network infrastructure. It can operate without a SIM and without network assistance and uses GNSS as its primary source for time synchronization.Verifying system functionality and performance exclusively by field testing in a real-world environment can be time-consuming, costly and very challenging. Requirements regarding functionality, and consequently the required assistance functions, are constantly changing. Due to this fact, test solutions are needed during the development and introduction phase to verify compliance with the standards. The PC5 direct communications type allows exchange of time sensitive and safety relevant information. Using a mobile communication tester like the R&S® CMW500 together with a C-V2X scenario simulation tool delivers reproducible test scenarios. This is essential for the standardization of verification processes for C-V2X in order to obtain reliable and comparable results, and it helps to demonstrate that end-to-end functionality between two C-V2X devices from different vendors works properly.
