NOTE 1: The band designations given are the MSR BS band designations. The relation between the band
designations for MSR BS and the designations for NR, E-UTRA, UTRA and GSM/EDGE are given in
table 4.4-1 of ETSI TS 137 141 [1].
NOTE 2: The band is for NR and/or E-UTRA only.
NOTE 3: The band is for NR, E-UTRA and/or UTRA only.
NOTE 4: The band is for NR, E-UTRA and/or NB-IoT only.
NOTE 5: Void.
NOTE 6: In Europe according to [i.9] and [i.11], radio equipment in band 28 operates between 758 MHz and 791 MHz
for the transmitter (F = 758 MHz and F = 791 MHz) and between 703 MHz and 736 MHz for the
DL_low DL_high
receiver (FUL_low = 703 MHz and FUL_high = 736 MHz).
NOTE 7: In Europe according to [i.22] and [i.24], radio equipment in band 41 operates between 2 570 MHz and
2 620 MHz (F = 2 570 MHz and F = 2 620 MHz).
DL_low DL_high
NOTE 8: In Europe according to [i.7] and [i.25], radio equipment in band 77 operates between 3 400 MHz and
4 200 MHz (F = 3 400 MHz and F =4 200 MHz).
DL_low DL_high
NOTE 9: In Europe according to [i.7] and [i.25], radio equipment in band 78 operates between 3 400 MHz and
3 800 MHz (FDL_low = 3 400 MHz and FDL_high = 3 800 MHz).
NOTE 10: Restricted to NR and/or E-UTRA operation when carrier aggregation is configured. The downlink operating
band is paired with the uplink operating band (external) of the carrier aggregation configuration that is
supporting the configured Pcell.
NOTE 11: Restricted to UTRA operation when dual band is configured (e.g. DB-DC-HSDPA or dual band 4C-HSDPA).
The down link frequency(ies) of this band are paired with the uplink frequency(ies) of the other FDD band
(external) of the dual band configuration.
NOTE 12: The band is for NR only.
NOTE 13: The band is for E-UTRA and/or UTRA only.
NOTE 14: The band is for E-UTRA and/or NB-IoT only.
NOTE 15: The band is for E-UTRA only.
NOTE 16: This band includes two frequency ranges that are harmonised in Europe:
(a) According to [i.23] and [i.24], radio equipment in band 65 operates between 2 110 MHz to 2 170 MHz
for the transmitter (F = 2 110 MHz and F = 2 170 MHz), and between 1 920 MHz to
DL_low DL_high
1 980 MHz for the receiver (FUL_low = 1 920 MHz and FUL_high = 1 980 MHz).
(b) Based on [i.25], radio equipment in band 65 operates between 2 170 MHz to 2 200 MHz for the
transmitter (F = 2 170 MHz and F = 2 200 MHz) and between 1 980 MHz to 2 010 MHz for
DL_low DL_high
the receiver (FUL_low = 1 980 MHz and FUL_high = 2 010 MHz) as the Complementary Ground
Component (CGC) of a Mobile-satellite service by reference to the present Harmonised Standard.

NOTE 1: For BS capable of multi-band operation, the supported operating bands may belong to different Band
Categories.
The present document covers conducted requirements for multi-RAT capable NR, E-UTRA, UTRA and GSM/EDGE
MSR Base Stations for 3GPP™ Release 9, 10, 11, 12, 13, 14 and 15. This includes the requirements for MSR operating
bands from 3GPP Release 16.
NOTE 2: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.1] is given in annex A.

Introduction
The present document is part of a set of standards developed by ETSI that are designed to fit in a modular structure to
cover radio equipment within the scope of the Radio Equipment Directive [i.1]. The present document is produced
following the guidance in ETSI EG 203 336 [i.2] as applicable.

1 Scope
The present document specifies technical characteristics and methods of measurements for the following equipment
types:
• Multi-Standard Radio capable Base stations (NR, E-UTRA, UTRA, GSM/EDGE, NB-IoT).
Operation of NR in combination with UTRA or GSM/EDGE is not supported.
These radio equipment types are capable of operating in all or any part of the frequency bands given in table 1-1.

table 4.4-1 of ETSI TS 137 141 [1].
NOTE 2: The band is for NR and/or E-UTRA only.
NOTE 3: The band is for NR, E-UTRA and/or UTRA only.
NOTE 4: The band is for NR, E-UTRA and/or NB-IoT only.
NOTE 5: Void.
NOTE 6: In Europe according to [i.9] and [i.11], radio equipment in band 28 operates between 758 MHz and 791 MHz
for the transmitter (F = 758 MHz and F = 791 MHz) and between 703 MHz and 736 MHz for the
DL_low DL_high
receiver (FUL_low = 703 MHz and FUL_high = 736 MHz).
NOTE 7: In Europe according to [i.22] and [i.24], radio equipment in band 41 operates between 2 570 MHz and
2 620 MHz (F = 2 570 MHz and F = 2 620 MHz).
DL_low DL_high
NOTE 8: In Europe according to [i.7] and [i.25], radio equipment in band 77 operates between 3 400 MHz and
4 200 MHz (F = 3 400 MHz and F =4 200 MHz).
DL_low DL_high
NOTE 9: In Europe according to [i.7] and [i.25], radio equipment in band 78 operates between 3 400 MHz and
3 800 MHz (FDL_low = 3 400 MHz and FDL_high = 3 800 MHz).
NOTE 10: Restricted to NR and/or E-UTRA operation when carrier aggregation is configured. The downlink operating
band is paired with the uplink operating band (external) of the carrier aggregation configuration that is
supporting the configured Pcell.
NOTE 11: Restricted to UTRA operation when dual band is configured (e.g. DB-DC-HSDPA or dual band 4C-HSDPA).
The down link frequency(ies) of this band are paired with the uplink frequency(ies) of the other FDD band
(external) of the dual band configuration.
NOTE 12: The band is for NR only.
NOTE 13: The band is for E-UTRA and/or UTRA only.
NOTE 14: The band is for E-UTRA and/or NB-IoT only.
NOTE 15: The band is for E-UTRA only.
NOTE 16: This band includes two frequency ranges that are harmonised in Europe:
(a) According to [i.23] and [i.24], radio equipment in band 65 operates between 2 110 MHz to 2 170 MHz
for the transmitter (F = 2 110 MHz and F = 2 170 MHz), and between 1 920 MHz to
DL_low DL_high
1 980 MHz for the receiver (FUL_low = 1 920 MHz and FUL_high = 1 980 MHz).
(b) Based on [i.25], radio equipment in band 65 operates between 2 170 MHz to 2 200 MHz for the
transmitter (F = 2 170 MHz and F = 2 200 MHz) and between 1 980 MHz to 2 010 MHz for
DL_low DL_high
the receiver (FUL_low = 1 980 MHz and FUL_high = 2 010 MHz) as the Complementary Ground
Component (CGC) of a Mobile-satellite service by reference to the present Harmonised Standard.

NOTE 1: For BS capable of multi-band operation, the supported operating bands may belong to different Band
Categories.
The present document covers conducted requirements for multi-RAT capable NR, E-UTRA, UTRA and GSM/EDGE
MSR Base Stations for 3GPP™ Release 9, 10, 11, 12, 13, 14 and 15. This includes the requirements for MSR operating
bands from 3GPP Release 16.
NOTE 2: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.1] is given in annex A.
