基于频率域灵活划分的5G实时调度算法

A real-time scheduling algorithm based on flexible frequency resources in 5G

5G网络的出现使无线技术在工业控制系统中的全面应用成为可能。目前,工业控制系统中存在大量高实时数据需通过无线网络进行传输,但已有的传输调度方法无法适用于频率域可灵活拆分的5G网络。因此,文章针对5G时频使用规则,基于经典装箱算法,提出一种对5G时频资源分类细化处理的启发式调度方法。评估测试表明文章所提方法与传统调度方法相比数据传输延时减小了28%。

The emergence of 5 G networks has made possible the full-scale application of wireless technology in industrial control systems. At present, there is a large amount of high real-time data in industrial control systems to be transmitted through wireless networks, but the existing transmission scheduling methods cannot be applied to 5 G networks with flexible splitting of frequency domain. Therefore, this paper proposes a heuristic scheduling method based on the classical boxing algorithm to classify and refine 5 G time-frequency resources for 5 G time-frequency usage rules. Evaluation tests show that the proposed method reduces the data transmission delay by 28% compared with the traditional scheduling method.
