摘要

针对LTE-Advanced中的5个关键技术，选择MIMO增强技术进行深入研究和阐述。从技术原理、算法实现、测试验证、网络兼容性多个维度讨论了LTE-Advanced下行传输模式9（TM9），分析了TM9的使用范围、性能优势和兼容性问题；并在此基础上，横向对比了LTE和LTE-Advanced的所有天线模式，给出布网建议。

Abstract

MIMO enhancement was studied and investigated out of five key technologies in LTE-Advanced system. Based on the technique theory

algorithm implement and test trail of transmission mode 9 were well disscussed. The utilization method

performance advantages and network compatibility of transmission mode 9 were also analyzed. Furthermore

all downlink transmission modes of LTE and LTE-Advanced were compared

and some suggestions were provided for network planning.
