2、5G频点号（NR-ARFCN）计算
FREF = FREF-Offs + ΔFGlobal (NREF – NREF-Offs)
式中，FREF-Offs和NREF-Offs由下表给出，NREF即NR-ARFCN。

2.1 计算实例
例1：中国移动频段2515MHz-2675MHz频点号计算
由FREF = (2515+2675)/2 MHz = 2545 MHz
因此2545 = 0+0.005(NREF -0)
得NREF = 509000
又需被30/5=6整除（频带信道栅格是全局频率栅格整数倍），取NREF = 509004
例2：中国联通频段3400MHz-3500MHz频点号计算
由FREF = (3400+3500)/2 MHz = 3450MHz
因此3450 = 3000+0.015(NREF -600000)
得NREF = 603000
满足被30/15=2整除（频带信道栅格是全局频率栅格整数倍），故NREF = 603000
