1.What is ?
-----RF Reference Frequency
The global frequency channel raster defines a set of RF reference frequencies .The RF reference frequency is used in signalling to identify the position of RF channels, SS blocks and other elements. 38101-1-f30 5.4.2
频率是一系列连续的值，如3.4567GHz，3.6666GHz，那么有哪些频率值可以用来标记载波的中心频点或者SSB的频点呢，与LTE一样，NR的协议中定义了表格5.4.2.1-1：NR-ARFCN parameters for the global frequency raster
