LTE系统小区间干扰协调技术研究
首发时间:2009-12-17
摘要:LTE系统是一种使用多输入多输出(MIMO)以及正交频分复用(OFDM)的下一代宽带无线通信系统。如何减小小区间干扰是LTE系统需要重点研究的问题之一。有很多针对小区间干扰的新技术应运而生,干扰协调技术就是其中最主要的一种。本文主要介绍了小区间干扰协调的多种方法以及如何将干扰协调技术与频域资源调度技术有效结合,并提供了系统级仿真结果。

Research on the Inter-Cell Interference Coordination in LTE System
Abstract:The Multi-Inputs-Multi-Outputs and Orthogonal Frequency Division Multiplexing are implemented in LTE system, which is a broadband wireless communication system. How to reduce the inter-cell interference is one of the most important subjects in LTE system. Inter-Cell Interference Coordination is one of the technologies, which are raised to overcome the inter-cell interference. In this paper, the inter-cell interference coordination technologies are introduced. And the combination of interference coordination with frequency resource scheduling also been mentioned. In the end, the system level simulation results are provided.
Keywords: LTE inter-cell interference coordination resource scheduling
