Overview of LTE for Vehicular Communications
WIRELESS PERSONAL COMMUNICATIONS(2020)
摘要
This article provides an overview about vehicle-to-everything communications in relation to the latest Long Term Evolution (LTE) standards. We describe the main vehicular services and give a brief review of vehicular communication systems over LTE for both infrastructure-to-vehicle communications over the broadcast/multicast LTE service and vehicle-to-vehicle communications over the LTE sidelink. Next, we analyze the performance of vehicular systems using link simulations for different vehicular channel models implemented on a LTE simulator called WM-SIMA. Finally, we draw some conclusions about the impact of using different modulation and coding scheme as well as the interference level on the overall performance.
