Study on Configuration of Frame Structure in TD-LTE System

针对TD-LTE无线网络规划中时隙规划的需要,对TD-LTE小区帧配置方法进行了研究。首先归纳总结了TD-LTE系统吞吐量计算方法,通过仿真,验证了TD-LTE帧配置对系统容量的影响。然后研究了TD-LTE单业务小区的帧配置方法,设计建立了基于帧结构的TD-LTE小区业务吞吐量仿真平台,并对单业务小区的用户平均吞吐量进行了仿真分析,给出了部分单业务小区的最佳帧配置建议。最后,仿真分析了多业务小区的用户平均吞吐量,给出了部分混合业务下小区的最佳帧配置建议。

Aiming at the requirement of the timeslot plan which is a part of the network plan of TD-LTE,the configuration of the frame structure of TD-LTE system is studied in this paper.First,a kind of calculation method of TD-LTE system throughput is concluded,and it is verified that the configuration of the frame structure of TD-LTE will influence the capacity of the system by simulation.Then the method of the configuration of the frame structure of TD-LTE in the cell which contain only one service is researched,and a simulation platform of the throughput of the service in the cell of TD-LTE system is created based on frame structure.Then the average throughput of the users in the cell is simulated,and advice of the configuration of the frame structure is given.At last,the users＇ average throughput in the cell which contain several kind of services is simulated and analyzed,and advice of the configuration of the frame structure in this cells is given.
