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 BS transmit / UE receive FDL_low   –  FDL_high	Duplex Mode

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).

NR CA Band	NR Band (Table 5.2-1)
CA_n77C	n77
CA_n78C	n78
CA_n79C	n79

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 N_RB values w.r.t each Channel bandwidth and SCS.

SCS (kHz)	5MHz	10MHz	15MHz	20 MHz	25 MHz	30 MHz	40 MHz	50MHz	60 MHz	80 MHz	100 MHz
	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
30	11	24	38	51	65	[78]	106	133	162	217	273
60	N/A	11	18	24	31	[38]	51	65	79	107	135

Maximum transmission bandwidth configuration N_RB

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 

SCS (kHz)	5 MHz	10 MHz	15 MHz	20 MHz	25 MHz	30 MHz	40 MHz	50MHz	60 MHz	80 MHz	100 MHz
15	242.5	312.5	382.5	452.5	522.5	[592.5]	552.5	692.5	N/A	N/A	N/A
30	505	665	645	805	785	[945]	905	1045	825	925	845
60	N/A	1010	990	1330	1310	[1290]	1610	1570	1530	1450	1370
