论文摘要
随着移动交通需求的爆炸性增长，宏观细胞的密集部署的小细胞具有巨大的5G和无线网络的潜力。在本文中，我们考虑了通过利用三个高频频段（即28GHz频段，E波段和Terahertz（THZ）频段）来支持各种QoS要求的交通流的问题。这三个乐队的合作有助于最大程度地满足流量的数量。为了解决公式的非线性整数编程问题，我们提出了一个三频调度方案，可以在三个不同的频段之间选择每个流量的最佳调度带。所提出的方案还有效地利用资源来安排时间插槽中的流动传输。广泛的模拟证明了所提出的方案的出色性能超过了三个基线方案，相对于完成的流量和系统吞吐量。
With the explosive growth of mobile traffic demand, densely deployed small cells underlying macrocells have great potential for 5G and beyond wireless networks. In this paper, we consider the problem of supporting traffic flows with diverse QoS requirements by exploiting three high frequency bands, i.e., the 28GHz band, the E-band, and the Terahertz (THz) band. The cooperation of the three bands is helpful for maximizing the number of flows with their QoS requirements satisfied. To solve the formulated nonlinear integer programming problem, we propose a triple-band scheduling scheme which can select the optimum scheduling band for each flow among three different frequency bands. The proposed scheme also efficiently utilizes the resource to schedule flow transmissions in time slots. Extensive simulations demonstrate the superior performance of the proposed scheme over three baseline schemes with respect to the number of completed flows and the system throughput.
