摘要

研究了如何在 LTE-Advanced系统异构网络中通过有效的增强型小区间干扰协调提高系统总吞吐量问题。通过分析网络中存在的干扰，建立数学模型，提出了一种基于减少发射功率几乎空白子帧的小区间联合干扰协调算法，利用优化方法研究系统总吞吐量和减少发射功率几乎空白子帧之间的关系，实现了最大化系统吞吐量，同时解决宏基站分配多少资源给微微小区，以及用户的接入选择问题。仿真结果表明，所提方法和对比方法相比，系统总吞吐量有19.8%提升，可以达到算法上限的97.4%，适用于对系统总吞吐量要求较高，而边缘用户性能要求较低的场景。

Abstract

The total system throughput was improved by means of enhanced inter-cell interference coordination (eICIC)in heterogeneous networks(HetNets)in LTE-Advanced system. Through analyzing the existing system interference

mathematical model was established and a joint optimization algorithm for eICIC was raised based on the reduced power almost blank subframe. By using this optimized method

the relationship between the total system throughput and the re-duced power almost blank subframe was studied

so as to realize the maximized total system throughput and solve the problems of the amount of radio resources that macro cells should offer to pico cells and UE assignments. Simulation re-sults show that

compared with the comparative method

the proposed method has 19.8% improvement in the total system throughput and the optimality gap is 97.4%. Conclusions can be drawn that the proposed method is suitable for the scene where the total system throughput requirement is relat vely high while the performance of the edge user requirement is relatively low.
