论文摘要
为了利用富裕资源以提高服务质量，已经考虑了高速铁路（HSR）通信系统的毫米波（MMWave）通信。在本文中，我们专注于安排尽可能多的流量，同时满足其QoS要求。由于干扰，窃听或其他问题，可能不会直接从轨道侧BS传输一些流。在本文中，我们提出了一种无人机辅助调度方案，该方案利用无人机作为这种流程的继电器。所提出的方案还使用两个MMWave频段，一个用于BS链接，另一个用于UAV链接。所提出的算法旨在满足其QoS要求最大化流量的数量。模拟表明，所提出的方案在完成的两个基线方案上的完整流量和系统吞吐量上实现了卓越的性能。
To exploit richer spectrum resources for even better service quality, millimeter wave (mmWave) communication has been considered for high-speed railway (HSR) communication systems. In this paper, we focus on scheduling as many flows as possible while satisfying their QoS requirements. Due to interference, eavesdropping, or other problems, some flows may not be directly transmitted from the track-side BS. In this paper, we propose an UAV-assisted scheduling scheme which utilizes a UAV to serve as relay for such flows. The proposed scheme also utilize two mmWave bands, one for the BS links and the other for the UAV links. The proposed algorithm aims to maximize the number of flows with their QoS requirements satisfied. Simulations demonstrate that the proposed scheme achieves a superior performance on the number of completed flows and the system throughput over two baseline schemes.
