摘要

TD-LTE系统在下行支持多种MIMO传输模式，各个传输模式可以根据信道状态的变化进行自适应切换，提高系统的性能。针对MIMO模式自适应需解决的首要问题，给出如何使用实际系统提供的有限的信道信息，通过自适应算法，最大程度获取可能的系统增益。为评估自适应算法的合理性，给出了性能验证结果。

Abstract

TD-LTE supports several MIMO transmission modes in downlink. Different mode has its favored radio environment，so the system performance can be improved if MIMO modes can adapt to the dynamic of radio condition. Pointing at the necessary channel information for the MIMO mode adaptation，the way on how to get them in TD-LTE system and the adaptation algorithm using this information were introduced. The evaluation results show the efficiency of the adaptation algorithm.
