摘要
At the time of the development, standardization, and further improvement are vital to the modern cellular systems such as the next generation wireless communication (5G). Simulations are essential to test and optimize algorithms and procedures prior to their implementation process of the equipment manufactures. In order to evaluate system performance at different levels, accurate simulations of simple setups, as well as simulations of more complex systems via abstracted models are necessary. In this work, two new simulators for the sidelink Cooperative- Vehicle-to-Everything (C-V2X) communication have been implemented and carried out on both the physical layer (Link-Level (LL)) and network layer (System-Level (SL)). Detailed methodologies of the LL and SL simulators for C-V2X communication have been illustrated. In the LL simulator, we get the mapping curves of BLER and Signal-to-Noise-Ratio (SNR), which are used as a baseline for measuring the performance of the LL simulation. In addition, these mapping curves are used as the important Link-to-System (L2S) interfaces. The SL simulator is utilized for measuring the performance of cell networking and simulating large networks comprising of multiple eNBs and UEs. Finally, the simulation results of both simulators for C-V2X communication are presented, which shows that different objectives can be met by using LL or SL simulations types.
