3gpp中NR规定了两个较大的频率范围。一个是我们通常所说的(sub 6 Ghz),另一个是我们通常所说的毫米波。根据范围的不同,最大带宽和子载波间隔会有所不同。在sub 6 Ghz,最大带宽为100兆赫,在毫米波范围内,最大带宽为400兆赫。一些子载波间隔(15,30 kHz)只能用于6 GHz以下,一些副载波间隔(120 kHz)只能用于毫米波范围,一些副载波间隔(60 kHz)可以同时用于sub 6 Ghz和毫米波范围。

这个例子看起来很明显,说“信道带宽=最大传输带宽+两侧的保护带”,但下表中,可能不清楚,因为最大传输带宽是以RB为单位指定的,保护带是以千赫为单位。
为了澄清这一点,有一个简单的方程式和例子,如下所示:

GSCN称为全局同步栅格信道(Global Synchronization Raster Channel)。已经有了名为ARFCN的现有频率规范(光栅)时,为什么我们需要这种额外的频率规范?”.
3GPP 规范中没有明确解释,个人猜测如下:
当NSA中的NR被激活时,由于频率、子载波间隔等都是由LTE RRC连接重新配置消息配置的,因此UE不需要对SSB进行盲搜索。但在SA中,UE需要盲目检测SSB,因为UE需要在收到任何RRC(MIB、SIB)之前检测到SSB。如果用户需要基于ARFCN搜索SSB,则由于ARFCN光栅很窄,搜索时间太长。因此,以更宽的步长定义SSB搜索频率很有必要。
