C-V2X Large-scale Test Network Transmission Performance Data Analysis Method

Abstract

C-V2X, as an end-to-end wireless communication network for intelligent transportation system, may lead to degradation of its communication quality in the case of high vehicle density, and the large-scale field test provides a test environment for its possible situation. whether the communication performance of C-V2X system in the large-scale field test can meet the technical requirements is the premise of whether C-V2X system can be applied and promoted in China. At this stage, the data after the large-scale test is only analyzed in terms of time delay and packet error rate(PER), and only the analysis of these two indicators is not able to judge whether the equipment meets the technical indicators in the large-scale scenario. In this paper, we propose an analysis and evaluation scheme for the data after the communication performance of vehicle devices in large-scale tests, add the evaluation indexes of interval delay jitter and throughput, and propose some improvement schemes for the existing test data saving format.
