NR上下行同步过程研究

Uplink and Downlink Synchronization Process in NR

上行同步和下行同步是两个重要的物理层过程,是提高通信系统性能的关键所在。首先介绍了同步信号的生成和同步信道的设计;然后重点分析了上行同步、下行同步过程和UE如何一步步找到RMSI并得到小区唯一标识C-RNTI。通过对初始同步过程的研究,在实践组网信令中验证同步参数的作用,并提出了同步参数规划的建议。

As two important physical layer processes,uplink synchronization and downlink synchronization are the key to improving the performance of communication systems.Firstly,the generation of synchronization signal and the design of synchronization channel are introduced,and then the uplink and downlink synchronization process and how the UE finds the RMSI step by step and obtains the cell unique identifier C-RNTI emphatically analyzed.And through the research of initial synchronization process,the role of synchronization parameters is verified in the practice network signaling,and the suggestion on synchronous parameter planning finally proposed.
