论文摘要
毫米波（MMWave）通信是第五代（5G）无线网络的基石创新之一，这要归功于这些频带中的大量带宽。但是，要正确评估此类系统的性能，必须基于对MMWave信号的传播特征的深入了解，必须具有可靠的通道模型。在这方面，射线示踪剂可以提供高精度，而牺牲了显着的计算复杂性，从而限制了模拟的可扩展性。为了解决这个问题，在本文中，我们提出了可能的简化，可以降低MMWave环境中射线追踪的复杂性，而不会显着影响模型的准确性。我们评估了此类简化对链接级指标的影响，测试不同的配置参数和传播方案。
Millimeter-wave (mmWave) communication is one of the cornerstone innovations of fifth-generation (5G) wireless networks, thanks to the massive bandwidth available in these frequency bands. To correctly assess the performance of such systems, however, it is essential to have reliable channel models, based on a deep understanding of the propagation characteristics of the mmWave signal. In this respect, ray tracers can provide high accuracy, at the expense of a significant computational complexity, which limits the scalability of simulations. To address this issue, in this paper we present possible simplifications that can reduce the complexity of ray tracing in the mmWave environment, without significantly affecting the accuracy of the model. We evaluate the effect of such simplifications on link-level metrics, testing different configuration parameters and propagation scenarios.
