  In recent years, Cellular-Vehicle-to-Everything (CV2X) has been an emerging
area of interest attracting both the industry and academy societies to develop,
which is also a prominent emerging service for the next generation of the
cellular network (5G). In the time of the development, standardization, and
further improvement of 5G, so simulations are essential to test and optimize
algorithms and procedures prior to their implementation process of the
equipment manufactures. And CV2X communication is used for information exchange
among the traffic participants with network-assisted which can reduce traffic
accidents and improve traffic efficiency. Moreover, it is also the primary
enabler for cooperative driving. But CV2X communication has to meet different
Quality of Service (QoS) requirements (e.g., ultra-high reliability (99.999%)
and ultra-low latency). Guaranteeing high-level reliability is a big challenge.
In order to assess system performance, accurate simulations of simple setups,
as well as simulations of more complex systems via abstracted models are
necessary for the CV2X communication. For checking the performance of the C-V2X
communication on a highway scenario, a system-level simulator has been
implemented. And, this simulation has been carried out on the network
(system-level) context. Finally, the analysis and the simulation results for
the C-V2X communication are presented, which shows that different objectives
can be met via system-level simulation.
