论文摘要
通过提供多GBPS数据速率，毫米波（MMWave）频段被认为是下一代移动网络的强大关键推动器。但是，他们严重的路径和对阻塞的敏感性在实际实施中提出了挑战。减轻这些效果并增加通信范围的一种有效方法是结合继电器。在本文中，我们专注于两个典型的MMWave继电器网络，对于每个网络，我们提出了三种光束调度方法来接近网络信息理论能力。所提出的梁调度方法包括确定性的水平连续边缘着色（HC-EC）调度程序，自适应背压（BP）调度程序和自适应低 - 延迟新的新反压（NEWBP）调度程序。借助计算机模拟，我们表明在网络容量范围内，提议的调度程序为网络稳定性提供了良好的保证，同时达到了非常低的数据包端到端延迟。
Millimeter wave (mmWave) bands are considered a powerful key enabler for next generation (5G) mobile networks by providing multi-Gbps data rates. However, their severe pathloss and sensitivity to blockage present challenges in practical implementation. One effective way to mitigate these effects and to increase communication range is beamforming in combination with relaying. In this paper, we focus on two typical mmWave relay networks and for each network, we propose three beam scheduling methods to approach the network information theoretic capacity. The proposed beam scheduling methods include the deterministic horizontal continuous edge coloring (HC-EC) scheduler, the adaptive back pressure (BP) scheduler and the adaptive low-delay new back pressure (newBP) scheduler. With the aid of computer simulations, we show that within the network capacity range, the proposed schedulers provide good guarantees for the network stability, meanwhile achieve very low packet end-to-end delay.
