Research on Business Requirements and Network Performance under Typical LTE-V2X Scenarios

In recent years, the IoV industry has developed rapidly and has gradually matured in terms of standardization, industrial chain and application demonstration, and basically has the conditions for large-scale trial commercial use. At present, there is no systematic method for planning, construction, and optimization of the IoV network in the industry, and the overall performance of the V2X lacks quantitative evaluation methods and basis. In this paper, application classification of LTE- V2X technology is first introduced. Then V2I service requirements and test results of coverage performance under the high-speed scenario and the viaduct scenario describes are presented. Deployment suggestions for the typical scenarios are also provided. For the V2X network in the high-speed straight scenario, RSU has good coverage effect, with a coverage distance of more than 1km. However, due to the change of the surrounding environment, jitter and obvious inflection points appear around the coverage limit distance. For the viaduct scenario, if it is not convenient to deploy RSUs, RSU equipment can be deployed under the bridge to cover the surface of the bridge deck, and the signal radiation effect can be improved by increasing the deployment height of RSU.
