5G Stuff: NR Frequency bands - FR1 or Sub6 GHz


As per 3GPP TS 38101-1 (Rel15, 2018-03) version, 5G is expected to be operated in two Frequency Ranges (FR1 and FR2) and the bands in each FR as below



Frequency range designation
Corresponding frequency range
FR1
450 MHz – 6000 MHz
FR2
24250 MHz – 52600 MHz

Definition of frequency ranges

FR1 is also called as Sub-6 and FR2 is called as mmWave. 

FR1 is further split into different bands as below with UL and DL freq bands with Operating mode.


NR operating band
Uplink (UL) operating band
BS receive / UE transmit
FUL_low   –  FUL_high
Downlink (DL) operating band

NR operating bands in FR1

Please note that some bands will be supporting either UL or DL (SUL means Supplementary Uplink and SDL means Supplementary Downlink).

Intra-band contiguous CA operating bands in FR1


In FR1, Sub-carrier spacing takes either of 15/30/60 kHz unlike 15 kHz in LTE and the Channel bandwidth is scalable from 5 MHz to 100 MHz unlike 1.4/3/5/10/20 MHz in LTE. Below are the NRB values w.r.t each Channel bandwidth and SCS.

Maximum transmission bandwidth configuration NRB


The minimum guardbands have been calculated using the following equation: (CHBW x 1000 (kHz) - RB value x SCS x 12) / 2 - SCS/2, where RB values are from the above table
