摘要
为满足TD-LTE系统对实时性的要求,通过对媒体接入控制(MAC)层和物理层之间的实时性研究以及对操作系统Nucleus PLUS的机制分析,实现了MAC层子帧调度。根据TD-LTE无线综合测试仪中的设计要求,详细介绍了Nucleus PLUS任务循环调度以及MAC子帧调度的流程设计。在实现MAC层基本功能的同时满足了TD-LTE对系统实时性、子帧同步与任务资源管理的需求。
Base on the real-time requirements in TD-LTE system,the sub-frame scheduling of MAC layer has been achieved based on the study of real-time between the MAC layer and physical layer and the analysis of Nucleus PLUS operating mechanism.According to the real-time requirements in TD-LTE wireless comprehensive tester, loop scheduling mechanism of Nucleus PLUS task has been described in detail and the MAC sub-frame scheduling process has been designed. While the basic functions of the MAC layer has been realized, the real-time capability of the TD-LTE and the needs of sub-frame synchronization with the resource management of task have been met.
