摘要
首先分析了中国移动可以使用的频率资源,建议随着3G用户的大幅减少,采用SUL方式在A频段上部署5G网络,以增加上行峰值速率和降低空中接口时延,然后给出了SUL载波和NUL载波的调度方式以及SUL参数的配置原则和建议,最后给出了A频段、D频段和3.5 GHz频段的峰值速率,采用SUL方式,A频段和D频段的上行峰值速率可以达到407 Mbit/s。
Firstly this paper analyzes the available frequency resources for China Mobile,and suggests that with the decreasing 3G subscribers,the SUL method should be adopted to deploy 5G network inA band to increase uplink peak rate and reduce the delay of air interface.Secondly,the configuration principle and suggestions are given for the scheduling mode in SUL and NUL carriers as well as the SUL parameters.Finally,the peak rates in A band,D band and 3.5GHz band are given,where the uplink peak rates of A band and D band can reach 407 Mbit/s through the SUL method.
