摘　　要：Integrated sensing and communications(ISAC)is a potential technology of 6G,aiming to enable end-to-end information processing ability and native perception capability for future communication systems.As an important part of the ISAC application scenarios,ISAC aided vehicle-to-everything(V2X)can improve the traffic efficiency and safety through intercommunication and synchronous perception.It is necessary to carry out measurement,characterization,and modeling for vehicular ISAC channels as the basic theoretical support for system design.In this paper,dynamic vehicular ISAC channel measurements at 28 GHz are carried out and provide data for the characterization of non-stationarity characteristics.Based on the actual measurements,this paper analyzes the time-varying PDPs,RMSDS and non-stationarity characteristics of front,lower front,left and right perception directions in a complicated V2X scenarios.The research in this paper can enrich the investigation of vehicular ISAC channels and enable the analysis and design of vehicular ISAC systems.
