摘　　要：资源调度是TDLTE系统空中接口的关键技术,信道质量指示(CQI,Channel qualityindication)又是资源调度最重要的考虑因素之一。首先介绍了CQI信号的定义、在TDLTE系统中位置及计算流程,接着详细阐述了CQI 2种反馈机制结构模式、承载的物理信道和不同的上报格式等,最后在公司TDLTE系统空中接口测试环境下,对CQI信号进行实际的测试验证,并对测试结果进行研究分析。Resource scheduling is the key technology of air interface based on TDLTE system, and CQI （Channel Quality Indication scheduling, too. This paper first outlines the ） is a most important factor in resource definition of CQI signal, the location in LTE system and the calculation process, and then describes the two CQI including structure mode, physical channel, different report formats, response mechanisms, and so on. Finally, the CQI signal is verified in the testing environment of TDLTE system, and the result also analyzed in detail.
