5GNR TS38.101, 104 Channel Raster频率栅格与NR-ARFCN
FR1频点对应TS38.101-1 5.4.2 Channel raster一节FR2频段对应TS38.101-2 5.4.2 Channel raster需要注意的是TS 38.101-1(-2) Table 5.2-1 定义的工作频段范围是表示整个载波 CBW 的边界。 载波中心频率 F_REF 只是确定载波位置的参考点载波的整体频谱占用包括保护带必须全部落在 F_low 和 F_high 之间否则该信道号码不得使用。简单来说整个载波带宽CBW必须完整地包含在表 5.2-1 所定义的工作频段范围内而不仅仅是中心频率 F_REF 落在频段内即可。如果仅F_REF落在频段内但是CBW的部分频带落在带外则这个F_REF不可用。所以说实际能够使用的载波中心频率F_REF要使得整个CBWChannel Bandwidth包含Transmission Bandwidth和GuardBand都必须处于TS 38.101-1(-2) Table 5.2-1 定义的工作频段范围内才行。原文NOTE 1:The channel numbers that designate carrier frequencies so close to the operating band edges that the carrier extends beyond the operating band edgeshall not be used.TS38.101-1 5.4.2.3 Channel raster entries for each operating bandNOTE1:These channel numbers shall also be such that the minimum guard band for each channel bandwidth and SCS specified in Table 5.3.3-1 are met for carriers located at the upper or lower edge of an operating band.TS38.101-1 5.4.2.3 Channel raster entries for each operating band
