在NR中,3GPP主要指定了两个频点范围。一个是我们通常称为Sub 6GHz,另一个是我们通常称为毫米波(Millimeter Wave)。对于不同的频点范围,系统的带宽和子载波间隔都所有不同。
在Sub 6GHz,系统最大的带宽为100MHz而在毫米波中最大的带宽为400MHz。子载波间隔15KHz和30KHz只能用在Sub 6GHz,而120KHz子载波间隔只能用在毫米波中,60KHz子载波间隔可以同时在Sub 6GHz和毫米波中使用。
下面的表格主要来自38.101-1 和38.101-2,汇总于此,方便查阅。
如上所述,3GPP为NR主要定义了两个频率范围:Sub 6GHz和毫米波。Sub 6GHz称为FR1,毫米波称为FR2。FR1和FR2具体的频率范围如下表所示:
TDD表示时分双工
FDD表示频分双工
SDL只能用于下行传输
SUL只能用于上行传输

<38.101-1表 5.3.2-1: FR1最大传输带宽与RB配置>
在上表5MHz带宽、15KHz子载波间隔中,一共包含25个RB。则这25个RB一共占用的带宽为:25个RB*每个RB12个RE*15KHz子载波间隔+一个保留RE(15KHz)=4515KHz。剩余的为保护间隔。其他情况同理。

ARFUN是用来表示频点的一个数,举个例子说明ARFUN的计算规则。以n1 band Uplink为例,其对应的频率范围为1920 MHz-1980 MHz。下表中的100KHz为频率步长,<20>表示ARFCN的步长。即384000表示1920 MHz这个频点,则384020表示(1920MHz+100KHz)这个频点,以此类推。
