论文摘要
本文涉及车辆到全能（V2X）通信的性能。更确切地说，我们分析了蜂窝网络中与安全相关的V2X通信的广播，假定基站和车辆共享相同的频谱，并且车辆向邻近用户广播其安全消息。我们将车辆的位置建模为Poisson Line Cox点过程，将用户的位置作为平面泊松点过程。我们假设当没有车辆在一定距离$ρ$之内没有车辆时，用户与最接近的基站关联。另一方面，位于车辆距离$ρ$范围内的用户与车辆接收安全消息相关联。我们使用随机几何框架量化了这种媒介物优先建立的结合的性质。我们得出接收车辆安全消息的用户的分数。然后，我们获得了在每种关联类型上评估的典型用户的信噪比比率的表达式。为了解决在蜂窝网络上的车辆广播的影响，该论文还得出了在这种情况下提供给典型用户的有效速度。
This paper concerns the performance of vehicle-to-everything (V2X) communications. More precisely, we analyze the broadcast of safety-related V2X communications in cellular networks where base stations and vehicles are assumed to share the same spectrum and vehicles broadcast their safety messages to neighboring users. We model the locations of vehicles as a Poisson line Cox point process and the locations of users as a planar Poisson point process. We assume that users are associated with their closest base stations when there is no vehicle within a certain distance $ ρ$. On the other hand, users located within a distance $ ρ$ from vehicles are associated with the vehicles to receive their safety messages. We quantify the properties of this vehicle-prioritized association using the stochastic geometry framework. We derive the fractions of users that receive safety messages from vehicles. Then, we obtain the expression for the signal-to-interference ratio of the typical user evaluated on each association type. To address the impact of vehicular broadcast on the cellular network, the paper also derives the effective rate offered to the typical user in this setting.
