Currently

LTE network below 6GHz spectrum is difficultto meet the growing demand for ultra-wideband.5Gcan 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 5Gin future.
