摘要
基于5G(第五代移动通信)的铁路下一代移动通信系统,将为未来智能铁路发展提供关键动力,如何利用有限的频谱资源,满足最大的平均业务容量和安全可靠的业务需求是一个重要问题。针对基于5G的铁路下一代移动通信,充分考虑了铁路特殊应用场景对频谱效率的影响,提出一种改进的频谱使用效率评估算法,并通过计算实例对算法的适应性进行了评估。
The next-generation railway mobile communication system based on 5G(fifth generation mobile communication)will be a key drive for the development of intelligent railway in the future.So,it is big problem to make use of limited spectrum resources to meet the needs of maximum average service capacity and safe and reliable services.For the next generation of railway mobile communication based on 5G,the influence of special railway application scenarios on spectrum efficiency is fully considered,an improved spectrum efficiency evaluation algorithm is proposed and the adaptability of the algorithm is evaluated by calculation cases.
