Tommaso Zugno, Matteo Drago, Marco Giordani, Michele Polese, Michele Zorzi

摘要:

3GPP NR V2X代表了下一代车载系统的新3GPP标准,除其他创新外,该标准还支持毫米波(mmWave)频谱中的车对车(V2 V)操作,以满足未来智能汽车网络的通信需求。虽然毫米波将实现大数据率和低延迟,但非常高频率下的传播特性变得非常具有挑战性,因此需要准确的性能评估作为适当评估此类系统性能的手段。在本文中,基于最新NR V2X规范的新型ns-3模块MilliCar用于提供毫米波V2 V网络的端到端性能评估。我们调查不同的传播场景和系统参数的影响,包括车辆间的距离,所采用的帧参数,以及调制和编码方案,并提供最有前途的V2 V部署配置的指导方针。

英文摘要:

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.
