Theoretical Maximum Blocking Capacity of LTE-V2X Intelligent Vehicle Network
In 2022,China's smart network technology is booming,the 5G-V2X standard has not been frozen,and LTE-V2X research has entered the stage of in-depth research.The purpose of this paper is to deduce the maximum network capacity of LTE-V2X vehicle network under severe vehicle congestion for practical intelligent network connection applications in China.This paper firstly introduces and analyzes lTE-V2X basic principles,protocol layer architecture,physical layer frame structure,verified signal fading model,maximum line of view estimation method,Frith transmission equation and other supporting papers and literatures that need to be applied,and then describes the V2X system capacity problems that need to be solved.The maximum capacity of LTE-V2X system was analyzed from the Angle of LTE channel fading,wireless interference and protocol transmission message.For the conclusion of wireless interference,SINR test results of actual LTE are used to verify its correctness.Finally,according to the principle that the system capacity depends on the minimum bottleneck in each link,it is concluded that the maximum capacity of the system is 2,12 and 0 respectively when the vehicle blocking radius is 1m,3m and 5m.
