Cellular-based vehicle-to-everything (C-V2X) is one of the emerging and promising techniques to support vehicular communications by enabling both safety-critical and non-safety services. C-V2X communications is a core solution to manage and advance future traffic safety and mobility. In this paper, we design a cellular-based vehicle-to-infrastructure (V2I) communications model for a Manhattan dense urban environment that has many roads deployed in the cell edge region, which results in severe co-channel interference (CCI). Thus, we aim to utilize two cooperative interference management schemes such as dynamic inter-cell interference coordination (ICIC) and coordinated multipoint (CoMP) to mitigate interference and to improve communication reliability. We evaluate the performance of the interference management schemes based on various performance indexes, such as vehicle UE average throughput, vehicle UE received interference, and vehicle UE outage probability. By effectively implementing the dynamic ICIC scheme, we achieve an immense reduction in CCI, which results in the improvement of user (UE) received signal quality. Moreover, we employ coordinated scheduling (CS) CoMP scheme to further mitigate the interference among cells. Finally, by implementing both dynamic ICIC and CS CoMP schemes simultaneously, a meaningful level of performance enhancement is achieved.

基于蜂窝的车用万物（C-V2X）是新兴的有前途的技术之一，它通过启用安全关键和非安全服务来支持车辆通信。C-V2X通信是管理和提高未来交通安全性和移动性的核心解决方案。在本文中，我们为曼哈顿密集的城市环境设计了基于蜂窝的车辆到基础设施（V2I）通信模型，该环境在小区边缘区域部署了许多道路，这会导致严重的同信道干扰（CCI）。因此，我们旨在利用两种协作式干扰管理方案，例如动态小区间干扰协调（ICIC）和协作多点（CoMP），以减轻干扰并提高通信可靠性。我们基于各种性能指标（例如，车辆UE平均吞吐量，车辆UE收到的干扰以及车辆UE中断概率）评估干扰管理方案的性能。通过有效地实施动态ICIC方案，我们实现了CCI的大幅降低，从而提高了用户（UE）接收信号的质量。此外，我们采用协调调度（CS）CoMP方案来进一步减轻小区之间的干扰。最后，通过同时实施动态ICIC和CS CoMP方案，可以达到有意义的性能增强水平。从而改善了用户（UE）接收信号的质量。此外，我们采用协调调度（CS）CoMP方案来进一步减轻小区之间的干扰。最后，通过同时实施动态ICIC和CS CoMP方案，可以达到有意义的性能增强水平。从而改善了用户（UE）接收信号的质量。此外，我们采用协调调度（CS）CoMP方案来进一步减轻小区之间的干扰。最后，通过同时实施动态ICIC和CS CoMP方案，可以达到有意义的性能增强水平。
