1 Scope
The present document covers the assessment of E-UTRA, E-UTRA with NB-IoT or NB-IoT base stations, repeaters and
associated ancillary equipment in respect of Electromagnetic Compatibility (EMC).
The present document specifies the applicable test conditions, performance assessment and performance criteria for E-
UTRA, E-UTRA with NB-IoT or NB-IoT base stations, repeaters and associated ancillary equipment in one of the
following categories:
- base sations of E-UTRA, E-UTRA with NB-IoT or NB-IoT meeting the requirements of TS 36.104 [2], with
conformance demonstrated by compliance to TS 36.141 [3].
- repeaters of E-UTRA meeting the requirements of TS 36.106 [4], with conformance demonstrated by
compliance to TS 36.143 [5].
Technical requirements related to the antenna port of E-UTRA, E-UTRA with NB-IoT or NB-IoT base stations or
repeaters are not included in the present document. These are found in the relevant product standards [2-5].
The environment classification used in the present document refers to the residential, commercial and light industrial
environment classification used in IEC 61000-6-1 [6] and IEC 61000-6-3 [7].
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.

4 Test conditions
4.1 General
The equipment shall be tested in normal test environment defined in base station conformance testing specification TS
36.141 [3] or in the E-UTRA repeater conformance testing specification TS 36.143 [5]. The test conditions shall be
recorded in the test report.
For an EUT which contains more than one BS, it is sufficient to perform tests relating to each type of port of each
representative type of the BS forming part of the EUT.
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 4.6.
Tests shall be performed relating to each type of port and all bands shall be assessed during the tests.
4.2 Arrangements for establishing a communication link
The wanted RF input signal nominal frequency shall be selected by setting the E-UTRA Absolute Radio Frequency
Channel Number (EARFCN) to an appropriate number.
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 air interface and/or the S1 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:
ETSI
3GPP TS 36.113 version 15.4.0 Release 15 11 ETSI TS 136 113 V15.4.0 (2019-10)
- the EUT shall be commanded to operate at maximum rated transmit power;
- Adequate measures shall be taken to avoid the effect of the unwanted signal on the measuring equipment;
- The wanted input signal level shall be set to a level where the performance is not limited by the receiver noise
floor or strong signal effects e.g.15 dB above the reference sensitivity level as defined in TS 36.141 [3] to
provide a stable communication link.
For immunity tests subclause 4.3 shall apply and the conditions shall be as follows.
4.2.1 Multiple enclosure BS solution
For a BS with multiple enclosures, the BS part with Radio digital unit and the Radio unit may be tested separately.
Communication link shall be set up in the same way as if they are in single BS enclosure. The Radio Digital unit and
the Radio unit shall communicate over an interface enabling establishment of a communication link.
4.3 Narrow band responses on receivers
Responses on receivers or duplex transceivers occurring during the immunity test at discrete frequencies which are
narrow band responses (spurious responses), are identified by the following method:
- if during an immunity test the quantity being monitored goes outside the specified tolerances (clause 6), it is
necessary to establish whether the deviation is due to a narrow band response or to a wide band (EMC)
phenomenon. Therefore, the test shall be repeated with the unwanted signal frequency increased, and then
decreased by 2 x BW MHz, where BW is the channel bandwidth as defined in TS 36.104 [2];
Channel Channel
- if the deviation disappears in either or both of the above 2 x BW MHz offset cases, then the response is
Channel
considered as a narrow band response;
- if the deviation does not disappear, this may be due to the fact that the offset has made the frequency of the
unwanted signal correspond to the frequency of another narrow band response. Under these circumstances the
procedure is repeated with the increase and decrease of the frequency of the unwanted signal set to 2.5 x
BW MHz;
Channel
- if the deviation does not disappear with the increased and/or decreased frequency, the phenomenon is considered
wide band and therefore an EMC problem and the equipment fails the test.
Narrow band responses are disregarded.
For BS capable of multi-band operation, all supported operating bands shall be considered for narrowband responses.
4.4 Test condition for Repeater
The wanted RF input signal nominal frequency shall be selected by setting the Absolute Radio Frequency Channel
Number (ARFCN) to an appropriate number within the operating band of the Repeater.
The Repeater path shall be tested with a suitable test system capable of measuring RF performance criteria (hereafter
called "the test system"). The test system shall be located outside of the test environment.
When the EUT is required to be in the operational mode, the following conditions shall be met:
- the EUT shall be commanded to operate at maximum rated gain;
- Adequate measures shall be taken to avoid the effect of the unwanted signal on the measuring equipment;
For immunity tests conditions subclause 4.3 shall apply.
4.4.1 Arrangements for test signals for repeaters
For immunity tests of repeaters, the wanted RF input signal shall be coupled to one antenna port at a level which will
result, when measured, in the maximum rated RF output power per channel, as declared by the manufacturer. The test
ETSI
3GPP TS 36.113 version 15.4.0 Release 15 12 ETSI TS 136 113 V15.4.0 (2019-10)
shall either be repeated with a wanted signal coupled to the other antenna port, or a single test shall be performed with
the specified input signals being simultaneously coupled to both antenna ports.
4.5 Exclusion bands
4.5.1 Transmitter exclusion band
For the purpose of EMC specifications there shall be a transmitter exclusion band.
- Lower carrier frequency used - 2.5 x BW MHz to upper carrier frequency used + 2.5 x BW MHz,
Channel Channel
where BW is the channel bandwidth as defined in TS 36.104 [2].
Channel
4.5.2 Receiver exclusion band
The receiver exclusion band for base stations is the frequency range over which no tests of radiated immunity of a
receiver are made. The receiver exclusion band is defined as:
F – Δf < f < F + Δf
UL,low OOB UL,high OOB
Where:
Values of FUL,low and FUL,high are defined for each operating band in TS 36.104 [2], subclause 5.5.
For E-UTRA, the value of Δf is 20 MHz.
OOB
For BS capable of multi-band operation, the total receiver exclusion band shall be the combination of the exclusion
bands for each operating band supported by the BS.
NOTE 1: The receiver exclusion bands do not apply for SDL bands.
NOTE 2: The receiver exclusion bands do not apply for Band 47.
4.6 BS test configurations
The present clause defines the BS test configurations that shall be used for demonstrating conformance. A single
E-UTRA carrier shall be used for testing of single-carrier capable BS. For other E-UTRA BS types, the test
configurations in Table 4.6.1 shall be used. The test configurations (ETCx) are defined in TS 36.141 [3], subclause
4.10.

5 Performance assessment
5.1 General
Following information shall be recorded in or annexed to the test report:
- the primary functions of the radio equipment to be tested during and after the EMC testing;
- the intended functions of the radio equipment which shall be in accordance with the documentation
accompanying the equipment;
- the method to be used to verify that a communications link is established and maintained;
- the user-control functions and stored data that are required for normal operation and the method to be used to
assess whether these have been lost after EMC stress;
- the ancillary equipment to be combined with the radio equipment for testing (where applicable);
- the information about ancillary equipment intended to be used with the radio equipment;
- information about the common and/or band-specific active RF components and other HW blocks for a
communication link in BS capable of multi-band operation;
- an exhaustive list of ports, classified as either power or signal/control. Power ports shall further be classified as
AC or DC power.
Performance assessment of a BS with multiple enclosures may be done separately for the BS part with the Radio digital
unit and the Radio unit respectively, according to the manufacturer's choice.
A communication link used by more than one operating band shall be assessed on all operating bands. Communication
link(s) and/or radio performance parameters for the operating bands can during the test be assessed simultaneously or
separately for each band, depending on the test environment capability.
5.2 Assessment of throughput in Downlink
The output of the transmitter shall be connected to an equipment which meet the requirements for the throughput
assessment of TS 36.101 [9] for the bearer used in the immunity tests. The level of the signal supplied to the equipment
should be within the range for which the assessment of throughput is not impaired. Power control shall be off during the
immunity testing.
5.3 Assessment of throughput in Uplink
The value of the throughput at the output of the receiver shall be monitored at S1 interface by using suitable test
equipment.
