【1】CMCC TDD LTE Band 38 Freq = (2570 ~ 2620)Mhz

【2】由：FDL = FDL_low + 0.1(NDL – NOffs-DL)

推出：

NDL = 10* (FDL – FDL_low ) + NOffs-DL

= 10* (FDL – 2750) + 37750

(1)低EARFCN = 10 * (2580 -2570) + 37750 = 37850

(2)中EARFCN = 10 * (2590 – 2570) + 37750 = 37950

(3)高EARFCN = 10 * (2600 – 2570) + 37750 = 38050

FDL為中心頻率，NDL為通道號，即頻點

如果對應到38350，反推中心頻率就是2630Mhz
