1 Scope
The present document covers the assessment of NR Base Station (BS) and ancillary equipment in respect of
Electromagnetic Compatibility (EMC).
The present document specifies the applicable requirements, procedures, test conditions, performance assessment and
performance criteria for NR base stations and associated ancillary equipment in the following categories:
- BS equipped with antenna connectors or TAB connectors which are possible to be terminated during EMC
testing, meeting the BS type 1-C and BS type 1-H RF requirements of TS 38.104 [2], with conformance
demonstrated by compliance to TS 38.141-1 [3].
- BS not equipped with antenna connectors nor TAB connectors, i.e. with antenna elements radiating during the
EMC testing, meeting the BS type 1-O and BS type 2-O RF requirements of TS 38.104 [2], with conformance
demonstrated by compliance to TS 38.141-2 [4].
Technical requirements related to the antenna and TAB connectors are not included in the present document. These are
found in the relevant product standards [2-4].
The environment classification used in the present document refers to the residential, commercial and light industrial
environment classification used in IEC 61000-6-1 [7], IEC 61000-6-3 [8] and IEC 61000-6-8 [33].
The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus at residential,
commercial and light industrial environments. The levels, however, do not cover extreme cases which may occur in any
location but with low probability of occurrence.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in TR 21.905 [1] and the following apply. A
term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905 [1].
ancillary equipment: electrical or electronic equipment, that is intended to be used with a receiver or transmitter
NOTE: It is considered as an ancillary equipment if:
- the equipment is intended for use with a receiver or transmitter to provide additional operational and/or control
features to the radio equipment, (e.g. to extend control to another position or location); and
- the equipment cannot be used on a stand alone basis to provide user functions independently of a receiver or
transmitter; and
- the receiver or transmitter, to which it is connected, is capable of providing some intended operation such as
transmitting and/or receiving without the ancillary equipment (i.e. it is not a sub-unit of the main equipment
essential to the main equipment basic functions).
antenna port: for EMC purposes, port for connection of an antenna used for intentional transmission and/or reception
of radiated RF energy, equivalent to an RF antenna connector/TAB connector in TS 37.105 [25].
BS type 1-C: NR base station operating at FR1 with requirements set consisting only of conducted requirements
defined at individual antenna connectors.
BS type 1-H: NR base station operating at FR1 with a requirement set consisting of conducted requirements defined at
individual TAB connectors and OTA requirements defined at RIB.
BS type 1-O: NR base station operating at FR1 with a requirement set consisting only of OTA requirements defined at
the RIB.
BS type 2-O: NR base station operating at FR2 with a requirement set consisting only of OTA requirements defined at
the RIB.
channel bandwidth: the RF bandwidth supporting a single NR RF carrier with the transmission bandwidth configured
in the uplink or downlink of a cell. The channel bandwidth is measured in MHz and is used as a reference for
transmitter and receiver RF requirements.
continuous phenomena: electromagnetic disturbance, the effects of which on a particular device or equipment cannot
be resolved into a succession of distinct effects (IEC 60050-161 [9]).
enclosure port: physical boundary of the equipment through which electromagnetic fields may radiate or impinge.
NOTE: In the case of integral antenna equipment, this port is inseparable from the antenna port.

exclusion band: frequency range(s) not subject to test or assessment.
free-space open area test site: reference test site with precautions to ensure that reflections do not influence the
measurement.
NOTE: The free-space open area test site (FSOATS) is the concept of the test site. A practical approximation is a
Fully-Anechoic Room (FAR).
fully-anechoic room: shielded enclosure, the internal surfaces of which are lined with radio-frequency-energy
absorbing material (i.e. RF absorber) that absorbs electromagnetic energy in the frequency range of interest.
integral antenna: antenna designed for permanent connection to the equipment and considered part of the enclosure
port.
NOTE: An integral antenna may be fitted internally or externally.
lower RF bandwidth edge: the frequency of the lower edge of the Base Station RF bandwidth, used as a frequency
reference point for transmitter and receiver requirements.
operating band: frequency range in which NR operates (paired or unpaired), that is defined with a specific set of
technical requirements.
port: particular interface of EUT used for EMC requirements testing purposes.
NOTE: Any connection point on EUT intended for connection of cables to or from EUT during the EMC testing
is considered as a port.

4.1 General
Requirements throughout the EMC specifications are in some cases defined separately for different frequency ranges
(FR). The frequency ranges FR1 and FR2 are defined in subclause 5.1 of TS 38.104 [2].
The equipment shall be tested in normal test environment defined in the corresponding BS conformance testing
specification TS 38.141-1 [3] for BS type 1-C and BS type 1-H, or TS 38.141-2 [4] for BS type 1-O and BS type 2-O.
The test conditions shall be recorded in the test report.
For BS capable of multi-band operation, the requirements in the present document apply for each supported operating
band unless otherwise stated. Operating bands shall be activated according to the test configuration in subclause 4.5.
Tests shall be performed relating to each type of port and all operating bands shall be assessed during the tests.
The manufacturer shall declare the supported operating band(s) according to the list of NR operating bands defined in
TS 38.104 [2].
NOTE 1: NR operating bands for BS type 1-C and BS type 1-H, are declared by the manufacturer according to the
declaration D.3 specified in TS 38.141-1 [3], table 4.6-1.
NOTE 2: NR operating bands for BS type 1-O and BS type 2-O, are declared by the manufacturer according to the
declaration D.4 specified in TS 38.141-2 [4], table 4.6-1.

4.2 Arrangements for establishing a communication link
The wanted RF input signal nominal frequency shall be selected by setting the NR Absolute Radio Frequency Channel
Number (NR-ARFCN) to an appropriate number, as defined in TS 38.104 [2], clause 5.4.2.3.
A communication link shall be set up with a suitable test system capable of evaluating the required performance criteria
(hereafter called "the test system") at the radio interface and telecommunication port(s) (the NG interface). The test
system shall be located outside of the test environment.
When the EUT is required to be in the transmit/receive mode, the following conditions shall be met:
- For the BS type 1-C and BS type 1-H testing, the EUT shall be commanded to operate at rated transmit power;
- For the BS type 1-O and BS type 2-O testing, the EUT transmit power shall be configured as stated in subclause
8.1 for emission test and subclause 9.1 for immunity test accordingly;
