在NR中,3GPP中规定了大约两个大的频率范围。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,最大带宽和子载波间隔会有所不同。在sub 6 Ghz中,最大带宽为100 Mhz,在毫米波范围内,最大带宽为400 Mhz。一些子载波间隔(15,30 Khz)仅可用于Sub 6 Ghz,并且一些子载波间隔(120 Khz)仅可用于毫米波范围,并且一些子载波间隔(60 Khz)可用于低于6 Ghz和毫米波范围。
以下是此处涉及的主题列表。在这个页面中没有那么多解释。它们大多是一堆表,但是一旦你开始开发(特别是测试)NR设备,你就会经常参考这些表。我只是想把这些表放在单页中,这样你就可以轻松找到这些信息。本页显示的大部分表格均为38.101-1和38.101-2。

2 频率范围
如上所述,在3GPP中定义了两种类型的频率范围。Sub 6 Ghz范围称为FR1,毫米波范围称为FR2。FR1(sub 6 Ghz)和FR2(毫米波)的确切频率范围定义如下。
<38.101-1 表5.1-1:频率范围的定义>
3 频谱和带宽
< 38.101-1图5.3.3-1一个NR信道的信道带宽和传输带宽配置的定义>
这个插图看起来很明显,说“通道BW =两侧的最大传输带宽+保护带”,但是当你看下面的表时,由于最大传输带宽是以RB为单位指定的,保护带是以khz为单位指定。
为了清楚说明这一点,我的日本朋友Tanaka Junya提出了一个简单的等式和例子,如下所示。
信道带宽(CBW)约为[N_RB x NumOfSubcarrier x SCS + GuardBand x 2]
,其中N_RB = 38.101-1中的最大传输带宽表5.3.2-1,38.101-2表5.3.2-1
NumberOfSubcarrier = 12(常数)
SCS =子载波间距=实验栏中的数字为(A)
在38.101-1表5.3.2-1,38.101-2表5.3.2-1
GuardBand = 38.101-1表5.3.3-1,38.101-2表5.3.3-1中C(C)部分的编号
示例>
在CBW = 5Mhz的情况下,SCS = 30 Khz,意味着38.101-1表5.3.2-1中的第二行
[N_RB x NumOfSubcarrier x SCS] = 11 x 12 x 30 = 3960 [kHz] -----(a)
[GuardBand x 2] = 505 x 2 = 1010 --------------------------------(b)
(a)+(b)= 3960 + 1010 = 4970 kHz = 4.970 Mhz,接近5 Mhz CBW
注意:保护带在表中定义为“最小”值,因此(a)+(b)可能与CBW不完全相同,但足够接近CBW

6 GSCN
当我第一次看到称为GSCN(全局同步光栅通道)的频率规范时。我问自己'为什么我们需要这种额外的频率规格,当我们已经有现有的频率规格(光栅)称为ARFCN?'时。
我仍然不知道3GPP TS或TDocs中的官方答案(我未能在规范中找到答案)。所以我想出了如下个人猜测:
当在NSA中激活NR时,UE不需要对SSB进行盲搜索,因为频率,子载波间隔等都是由LTE RRC连接重新配置消息配置的。但是在SA中,UE需要盲目地检测SSB,因为UE需要在它获得任何RRC(MIB,SIB)之前检测到它。如果UE需要基于ARFCN栅格搜索SSB,则ARFCN栅格非常窄,因此需要很长时间。因此,最好以更宽的步骤定义SSB搜索频率。这是GSCN的用途/目的。
