摘要

针对LTE系统中多用户下行吞吐量难以预测的问题，从LTE 系统的时域和频域资源出发，结合用户位置、终端类型以及下行MIMO模式等内容，分析了多用户条件下时域和频域调度算法的特点、影响因素和作用过程。并在此基础上建立了多用户下行吞吐量分析和估算模型，进而应用此模型对具体实例进行了预测和分析，从而对多用户性能分析工作起到一定的指导作用。

Abstract

Aiming at LTE multi-user downlink throughput

it was analyzed that from time domain and frequency domain of LTE resources

user location

UE category and downlink MIMO modes

also combined with the characteristics

influencing factors

action processes of time-domain and frequency-domain scheduling algorithms under multi-user conditions. The multi-user downlink throughput analysis and estimation model was then built based on this

and the model was used to analyze a real example. It would be beneficial for LTE performance optimization.
