摘要
首先介绍了5G NR和LTE在小区搜索和频率配置方面的差异,指出NR的频率配置涉及到信道栅格、同步栅格、Point A和系统带宽的配置。然后以3 400 MHz—3 500 MHz为例,给出了NR的信道栅格、同步栅格和Point A的配置方法,建议3 400 MHz—3 500 MHz的信道栅格配置为3 450 MHz(SCS=30 kHz)和3 450.18 MHz(SCS=60 kHz),同步栅格的位置配置为3 404.640 MHz,Point A的位置配置为3 400.860 MHz。最后,给出了3 400 MHz—3 500 MHz的信道栅格、同步栅格和Point A的示意图。
Firstly,the diff erence between the 5 G NR and the LTE in cell search and frequency configuration is introduced.It is pointed out that the NR frequency configuration is involved with channel raster,synchronization raster,Point A and the system bandwidth.Then,taking the 3 400 MHz-3 500 MHz for example,the configuration method of NR channel raster,synchronization raster and Point A.It is suggested that the configurations of channel raster,synchronization raster and Point A at 3 400 MHz-3 500 MHz are set as 3 450 MHz(SCS=30 kHz)and 3 450.18 MHz(SCS=60 kHz),3 404.640 MHz and 3 400.860 MHz,respectively.Finally,the schematics of channel raster,synchronization raster and Point A at 3 400 MHz-3 500 MHz are presented,respectively.
