Simulative Comparison of 4G/5G ITU Channel Models in the Context of V2I

Vehicle-to-Infrastructure (V2I) via mobile communication technologies such as Long Term Evolution (LTE) or 5G NR (New Radio) is a current research topic. In the context of the vision of autonomous driving many stakeholders are interested in the capabilities and shortcomings of these technologies. Several simulation frameworks are available which can be used for evaluation in large traffic scenarios. Especially the channel model used on the physical layer is of interest, because it is crucial for the assessment whether messages could be exchanged successfully. In this paper we look into the framework SimuLTE and its provided 4G channel models taken from International Telecommunication Union (ITU) guidelines (M.2135) and compare it with the latest corresponding ITU-guidelines (M.2412) for 5G NR simulating two sample scenarios and analyzing the different outcomes.
