-LTE系统终端上报CQI/PMI/RI过程的研究
Research on UE Procedure for Reporting CQI/PMI/RI in TD-LTE system
发射端通过获得终端上报的信道状态信息，调整数据流的调制编码方式以及预编码处理等，使通信质量达到最优。本文就TD-LTE系统终端上报CQI/PMI/RI的过程进行研究。针对PDSCH的处理流程分析了CQI、PMI、RI的定义及用途，总结分析了每一种上报模式，并就信道状态信息的控制信令进行说明。最后，依据终端一致性测试协议，分析终端信道状态信息上报能力的测试方法。
ccording to channel state information reported by UE, transmitter adjusts modulation and coding scheme and precoding method for data to get the best communication. This report focuses on studies of UE procedure for reproting CQI/PMI/RI in TD-LTE system .According to PDSCH procedure it analyzes the defination and purpose of CQI/PMI/RI. What's more, it summerizes each reporting module and describes control messages of channel state informatoin. Finally, this report provides a testing method to analyze ability of reporting based on UE Conformance Testing protocol.
