5G频段定义

1、子载波间隔

Table 5.1-1: Supported transmission numerologies.

从该表可以看出，numerology一共支持5种子载波间距：15kHz,30kHz,60kHz,120kHz,240kHz。对于PSS，SSS和PBCH所在的BWP，只支持子载波间距为15kHz，30kHz，120kHz和20kHz。用于上下行数据传输的numerology所支持的BWP对应的子载波间距为15kHz,30kHz,60kH和120kHz。

其中只有子载波间距60kH( = 2)支持extended CP。

2、FR1和FR2定义

Table 5.1-1: Definition of frequency ranges

Frequency range designation	Corresponding frequency range
FR1	410 MHz – 7125 MHz
FR2	24250 MHz – 52600 MHz

3、BAND定义

FR1和FR2BAND有两个表定义

 

4、最大传输带宽

 

Figure 5.3.1-1: Definition of the channel bandwidth and the maximum transmission bandwidth configuration for one NR channel

FR1 The maximum transmission bandwidth configuration NRB for each UE channel bandwidth and subcarrier spacing is specified in Table 5.3.2-1.

Table 5.3.2-1: Maximum transmission bandwidth configuration NRB

SCS (kHz)	5 MHz	10 MHz	15 MHz	20 MHz	25 MHz	30 MHz	40 MHz	50 MHz	60 MHz	80 MHz	90 MHz	100 MHz
	NRB	NRB	NRB	NRB	NRB	NRB	NRB	NRB	NRB	NRB	NRB	NRB
15	25	52	79	106	133	160	216	270	N/A	N/A	N/A	N/A
30	11	24	38	51	65	78	106	133	162	217	245	273
60	N/A	11	18	24	31	38	51	65	79	107	121	135

FR2 The maximum transmission bandwidth configuration NRB for each UE channel bandwidth and subcarrier spacing is specified in Table 5.3.2-1

Table 5.3.2-1: Maximum transmission bandwidth configuration NRB

SCS (kHz)	50 MHz	100 MHz	200 MHz	400 MHz
	NRB	NRB	NRB	NRB
60	66	132	264	N.A
120	32	66	132	264

 

5、资源栅格

ΔFGlobal全局频率栅格间隔(granularity of the global frequency raster)

FREF  RF reference frequencies

NR-ARFCN取值范围FR1为0…2016666，FR2为2016667 – 3279165，与RF reference frequency FRE的关系见下表。

FREF = FREF-Offs + ΔFGlobal (NREF – NREF-Offs)

channel raster 是RF reference frequencies的子集，对每个band来说，可用的见下表。

ΔFRaster为间隔粒度，大于等于ΔFGlobal。
