现有LTE(长期演进)网络所使用的6 GHz以下频段难以满足日益增长的网络带宽的需求, 而5G网络能够提供大量连续的频谱资源, 是未来无线网络的基础。针对多种无线接入应用场景, 提出影响频谱资源分配的各种因素和高低频段的一些分配方式。结果表明, 复用低频段和增加新的高频段空口能够满足5G网络的需求。

Currently,LTE network below 6 GHz spectrum is difficultto meet the growing demand for ultra-wideband. 5G can provide a large number of continuous spectrum bands, which is the foundation of the future wireless network. For a variety of application scenarios, the factors that affect the spectrum occupation and the ways of occupation for high and low frequency bands are proposed. The results show that re-using lower band and new higher band could meet requirements of 5G in future.
