LTE频点计算公式及频点号对应表

下行频点计算公式：

FDL = FDL_low + 0.1(NDL – NOffs-DL)

其中FDL为该载频下行频点，FDL_low对应频段的最低下行频点，NDL为该载频下行频点号，NOffs-DL对应频段的最低下行频点号。对应关系表详见表5.7.3-1。 上行频点计算公式：

FUL = FUL_low + 0.1(NUL – NOffs-UL)

其中FUL为该载频上行频点，FUL_low对应频段的最低上行频点，NUL为该载频上行频点号，NOffs-UL对应频段的最低上行频点号。对应关系表详见表5.7.3-1。

上下行频点号范围： 0 - 65535.

对应关系表详见表5.7.3-1如下：

电信目前可能分配FDD频段，给你的EARFCN是1750，则范围落在

FDL = FDL_low + 0.1(NDL – NOffs-DL)

FDL = 1805 + 0.1 * (1750 - 1200) = 1860 M 是下行的中心频点。

NDL = 10* (FDL – FDL_low ) + NOffs-DL

FDL:中心频率
