摘　　要：文章主要探讨5G移动通信基站的符号节能方法,通过确定5G小区下行业务的负荷值,低于负荷门限动态调整5G的业务信道资源(Resource Block,RB)在时域上的时隙调度或符号调度值,将资源粒度调至最小,同时在一个无线帧结构中,只保留单边带(Single Sideband,SSB)及导频,将时频域的调度粒子都更小化后,可关闭的下行符号在时频域达到最大化,从而进一步降低5G基站耗能。This paper mainly discusses the symbol energy saving method of 5G mobile communication base station.By determining the downlink service load value of 5G cell,the time slot scheduling or symbol scheduling value of 5G service channel Resource Block(RB)in the time domain is dynamically adjusted below the load threshold,and the resource granularity is adjusted to the minimum.Meanwhile,in a wireless frame structure,Only Single Sideband(SSB)and pilot are retained,and after the scheduling particles in the time-frequency domain are reduced,the downlink symbols that can be closed are maximized in the time-frequency domain,thus further reducing the energy consumption of 5G base stations.
