论文摘要
3GPP NR V2X代表了下一代车辆系统的新3GPP标准，除其他创新外，还支持毫米波（MMWave）频谱中车辆到车辆（V2V）操作，以满足未来智能自动网络的通信要求。尽管MMWAVES可以实现大量的数据速率和较低的延迟，但频率很高的传播特性变得非常具有挑战性，从而呼吁进行准确的性能评估，以此作为正确评估此类系统性能的手段。沿着这些行，在本文中，基于最新的NR V2X规范的新的NS-3模块用于提供MMWave V2V网络的端到端性能评估。我们研究了不同传播方案和系统参数的影响，包括车辆间距离，所采用的框架命理和调制和编码方案，并为最有希望的V2V部署配置提供指南。
3GPP NR V2X represents the new 3GPP standard for next-generation vehicular systems which, among other innovations, supports vehicle-to-vehicle (V2V) operations in the millimeter wave (mmWave) spectrum to address the communication requirements of future intelligent automotive networks. While mmWaves will enable massive data rates and low latency, the propagation characteristics at very high frequencies become very challenging, thereby calling for accurate performance evaluations as a means to properly assess the performance of such systems. Along these lines, in this paper MilliCar, the new ns-3 module based on the latest NR V2X specifications, is used to provide an end-to-end performance evaluation of mmWave V2V networks. We investigate the impact of different propagation scenarios and system parameters, including the inter-vehicle distance, the adopted frame numerology, and the modulation and coding scheme, and provide guidelines towards the most promising V2V deployment configurations.
