中文摘要：

提出一种基于神经网络预测信道质量指示（CQI）的长期演进下行调度方法，设计了基于神经网络的CQI预测模型，使用系统中已获得的CQI历史值来预测调度时刻的当前CQI值，调度器使用此预测值进行调度．仿真结果表明，该方法对由CQI延迟所导致的系统性能下降有明显改善．

英文摘要：

Using the available outdated channel quality indicator （CQI） , an optimized long term evolu- tion downlink resource allocation method is proposed. The key is a neural network based on CQI predic- tion model and algorithm, which can predict the current CQI from the outdated CQIs. The scheduler uses the predicted CQI to allocate radio resources and decide on proper modulation and coding scheme. Simu- lation shows that the proposed prediction model and algorithm have practical effects on solving the degra- dation of scheduling efficiency due to the outdated CQI.
