摘要:

C-V2X或LTE-V标准旨在支持V2X(车辆到一切)通信。该标准是LTE的演进,并且它已经由3GPP在版本14中发布。该新标准引入了C-V2X或LTE-V模式4,该模式专为使用PC 5侧链路接口的V2 V通信而设计,无需任何蜂窝基础设施支持。在模式4中,车辆自主选择和管理其无线电资源。模式4是高度相关的,因为V2 V安全应用不能依赖于基于基础设施的蜂窝覆盖的可用性。本文介绍了C-V2X或LTE-V模式4的通信性能的第一个分析模型。特别是,本文提出了平均PDR(数据包传输率)的分析模型,作为发送器和接收器之间距离的函数,以及C-V2X模式4中可能遇到的四种不同类型的传输错误。该模型进行了验证,为广泛的传输参数和交通密度。为此,本研究将分析模型获得的结果与在静脉上实施的C-V2X模式4模拟器获得的结果进行了比较。

英文摘要:

The C-V2X or LTE-V standard has been designed to support V2X (Vehicle to Everything) communications. The standard is an evolution of LTE, and it has been published by the 3GPP in Release 14. This new standard introduces the C-V2X or LTE-V Mode 4 that is specifically designed for V2V communications using the PC5 sidelink interface without any cellular infrastructure support. In Mode 4, vehicles autonomously select and manage their radio resources. Mode 4 is highly relevant since V2V safety applications cannot depend on the availability of infrastructure-based cellular coverage. This paper presents the first analytical models of the communication performance of C-V2X or LTE-V Mode 4. In particular, the paper presents analytical models for the average PDR (Packet Delivery Ratio) as a function of the distance between transmitter and receiver, and for the four different types of transmission errors that can be encountered in C-V2X Mode 4. The models are validated for a wide range of transmission parameters and traffic densities. To this aim, this study compares the results obtained with the analytical models to those obtained with a C-V2X Mode 4 simulator implemented over Veins.
