| 摘 要： | 针对LTE系统的动态不连续接收机制,系统分析了动态控制LTE DRX周期算法的引入背景,提出了一种基于自适应控制休眠周期的LTEDRX机制,并通过仿真平台对其性能进行了仿真验证。仿真结果表明该算法在能耗和时延2方面均具有良好的性能,可以实现两者之间的有效折衷与权衡。

| Abstract: | In order to enhance the use time and Standby time of UE, DRX technology served as a method of reducing the UE power loss in MAC layer is applied widely in mobile communication system. However, it is implacable between the power saving and delay of UE after the application of DRX technology. So, a new dynamic LTE DRX mechanism based on adaptive control of dormancy period is proposed in this paper. Simulation results prove this mechanism can ensure the power saving and satisfy the delay demand of different services. |
