1 Scope
rd
The present document establishes the essential EMC requirements for "3 generation" digital cellular mobile terminal
equipment and ancillary accessories in combination with a 3GPP E-UTRA user equipment (UE).
The equipment conforming to the requirements laid out in the present document and used in its intended
electromagnetic environment in accordance with the manufacturers instructions
- shall not generate electromagnetic disturbances at a level which may interfere with the intended operation of
other equipment;
- has an adequate level of intrinsic immunity to electromagnetic disturbances to operate as intended;
The present document specifies the applicable EMC tests, the methods of measurement, the frequency range, the limits
and the minimum performance criteria for all types of E-UTRA UE´s and their accessories. E-UTRA base station
equipment operating within network infrastructure is outside the scope of the present document. However, the present
document does cover mobile and portable equipment that is intended to be operated in a fixed location while connected
to the AC mains. E-UTRA base stations in the radio access network are covered by the technical specification
TS36.113 [2].
Requirements for the radiated emission from the enclosure port of integral antenna equipment and ancillaries have been
included. Technical specifications for conducted emissions from the antenna connector are found in the 3GPP
specifications for the radio interface, e.g. TS36.521 [3], for the effective use of the radio spectrum.
The immunity requirements have been selected to ensure an adequate level of compatibility for apparatus in residential,
commercial, light industrial and vehicular environments. The levels however, do not cover extreme cases, which may
occur in any location but with low probability of occurrence.
The environment classification used in the present document refers to the environment classification used in the Generic
Standards IEC 61000-6-1 [4], IEC 61000-6-3 [5], except the vehicular environment class which refers to
ISO 7637 Part 1 [6] and Part 2 [7].
Compliance of radio equipment to the requirements of the present document does not signify compliance to any
requirement related to the use of the equipment (i.e. licensing requirements).
Compliance to the requirements of the present document does not signify compliance to any safety requirement.
However, any temporary or permanent unsafe condition caused by EMC is considered as non-compliance.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply.
Ancillary equipment: Equipment (apparatus), used in connection with a user equipment (UE) is considered as an
ancillary equipment (apparatus) if:
- the equipment is intended for use in conjunction with a UE to provide additional operational and/or control
features to the UE, (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 UE; and
- the UE 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).
Average power: The average transmitter output power obtained over any specified time interval, including periods
with no transmission, when the transmit time slots are at the maximum power setting.
Camped on a cell: The UE is in idle mode and has completed the cell selection/reselection process and has chosen a
cell. The UE monitors system information and (in most cases) paging information. Note that the services may be
limited, and that the PLMN may not be aware of the existence of the UE within the chosen cell.
Channel bandwidth: The RF bandwidth supporting a single E-UTRA 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 (continuous disturbance): Electromagnetic disturbance, the effects of which on a particular
device or equipment cannot be resolved into a succession of distinct effects (IEC 60050-161 [8]).
Data application ancillary: Ancillary which provides send and/or receive data access to UMTS services via UE.
Enclosure port: Physical boundary of the apparatus through which electromagnetic fields may radiate or impinge. In
the case of integral antenna equipment, this port is inseparable from the antenna port.
End- User data: Manufacturer defined data patterns for data transfer testing. Represents EUT´s typical user application
(e.g. photo, video, text file, message) in its characteristics.
Idle mode: Idle mode is the state of User Equipment (UE) when switched on but with no Radio Resource Control
(RRC) connection.
Integral antenna: Antenna designed to be connected directly to the equipment with or without the use of an external
connector and considered to be part of the equipment. An integral antenna may be fitted internally or externally to the
equipment.
Maximum throughput: The maximum achievable throughput for a reference measurement channel.
Necessary bandwidth: For a given class of emission, the width of the frequency band which is just sufficient to ensure
the transmission of information at the rate and with the quality required under specified conditions.
ETSI
3GPP TS 36.124 version 16.3.0 Release 16 9 ETSI TS 136 124 V16.3.0 (2022-07)
Out of band emissions: Emission on a frequency or frequencies immediately outside the necessary bandwidth, which
results from, the modulation process, but excluding spurious emissions.
NOTE: Any unwanted emission which falls at frequencies separated from the centre frequency of the emission by
less than 250% of the necessary bandwidth of the emission will generally be considered out-of-band
emission.
Port: particular interface, of the specified equipment (apparatus), with the electromagnetic environment. For example,
any connection point on an equipment intended for connection of cables to or from that equipment is considered as a
port (see figure 1).
Spurious emission from ITU-R SM 329 [9]: Emission on a frequency, or frequencies, which are outside the necessary
bandwidth and the level of which may be reduced without affecting the corresponding transmission of information.
Spurious emissions include harmonic emissions, parasitic emissions, intermodulation products and frequency
conversion products but exclude out-of-band emissions.
Telecommunication port: Ports which are intended to be connected to telecommunication networks (e.g. public
switched telecommunication networks, integrated services digital networks), local area networks (e.g. Ethernet, Token
Ring) and similar networks (see CISPR 22 [10]).
Throughput: The number of payload bits successfully received per second for a reference measurement channel in a
specified reference condition.
Transient phenomena: Pertaining to or designating a phenomena or a quantity which varies between two consecutive
steady states during a time interval short compared with the time-scale of interest (IEC 60050-161 [8])
Traffic mode: Is the state of User Equipment (UE) when switched on and with Radio Resource Control (RRC)
connection established.
Universal mobile telecommunications system (UMTS): The telecommunications system, incorporating mobile
cellular and other functionality, that is the subject of specifications produced by 3GPP
User equipment (UE): is a "Mobile Station" (MS) which is an entity capable of accessing a set of UMTS services via
one or more radio interfaces. This entity may be stationary or in motion within the UMTS service area while accessing
the UMTS services, and may simultaneously serve one or more users.

4 Test conditions
4.1 General
The equipment shall be tested under normal test conditions according to the relevant product and basic standards (See
Annex E of TS 36.101 [11] for environmental conditions). If these conditions are not specified then the manufacturers
declared range of humidity, temperature and supply voltage shall be used. The test conditions shall be recorded in the
test report.
Whenever the Equipment under test (EUT) is provided with a detachable antenna, the EUT shall be tested with the
antenna fitted in a manner typical of normal intended use, unless specified otherwise.
Where the equipment incorporates an external 50 Ω RF antenna connector that is normally connected via a coaxial
cable, then the wanted signal to establish a communication link also uses a coaxial cable.
Where the equipment has an external 50 Ω RF antenna connector that is not normally connected via a coaxial cable or
where the equipment has no external 50 Ω RF connector (i.e., integral antenna equipment), then the wanted signal, to
establish a communication link, shall be delivered from the equipment to an antenna located within the test
environment.
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 base station simulator (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 traffic mode, a call is set up according to the Generic call set-up procedure and
the following conditions shall be met:
See TS 36.508 [12] and TS 36.509 [24] for details regarding generic call set-up procedure and throughput test loop
scenarios.
- Set and send continuously positive TPC commands to the UE;
ETSI
3GPP TS 36.124 version 16.3.0 Release 16 11 ETSI TS 136 124 V16.3.0 (2022-07)
- the DTX shall be disabled;
- uplink power control shall be enabled;
- transmitting and/or receiving (UL/DL) bit rate for reference test channel shall be the reference measurement
channel as specified in Annex C in TS 36.101 [11] with parameters specified in Table 7.3.1-1 and Table 7.3.1-2
in TS 36.101 [11];
- adequate measures shall be taken to avoid the effect of the unwanted signal on the measuring equipment;
- for immunity testing, the wanted input signal level shall be set to 40 dB above the reference sensitivity level to
provide a stable communication link. The reference sensitivity level is defined in TS 36.101 [11];
- for emission testing, the wanted input signal level shall be no more than 15 dB above the reference sensitivity
level, such that the performance of the measuring receiver is not limited by strong signal effects.
When the EUT is required to be in the idle mode, the following conditions shall be met:
- UE shall be camped on a cell
- UE shall perform Location Registration (LR) before the test, but not during the test;
- UE´s neighbour cell list shall be empty;
- Paging repetition period and DRX cycle shall be set to minimum (shortest possible time interval);
For immunity tests subclause 4.3, shall apply and the conditions shall be as follows:
4.3 Narrow band responses on receivers
Responses on receivers or duplex transceivers occurring during the 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, it is necessary to
establish whether the deviation is due to an unwanted effect on the receiver of the UE or on the test system
(narrow band response) or to a wide band (EMC) phenomenon. Therefore, the test shall be repeated with the
unwanted signal frequency increased or decreased by BW MHz, where BW is the channel bandwidth
Channel Channel
as defined in TS 36.101 [11];
- if the deviation does not disappear, the procedure is repeated the unwanted signal frequency increased or
decreased by 2 x BW MHz, where BW is the channel bandwidth as defined in TS 36.101 [11];

- 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.
The procedure above does not apply to conducted immunity tests in the frequency range 150 kHz to 80 MHz.
4.4 Receiver exclusion band
The receiver exclusion band for terminals extends from the lower frequency of the allocated receiver band minus
85 MHz to the upper frequency of the allocated receiver band plus 85 MHz. The receiver exclusion band for UE is the
frequency range over which no tests of radiated immunity of a receiver are made. The exclusions bands are as set out
below:
F – 85 < f < F + 85 (MHz)
DL,low DL,high
Where values of F and F are defined for each operating band in TS 36.101 [11], clause 5.5.
DL,low DL,high

5 Performance assessment
5.1 General
The manufacturer shall at the time of submission of the equipment for test, supply the following information to be
recorded in the test report:
- the primary functions of the radio equipment to be tested during and after the EMC testing;
- if applicable, the method to be used to verify that a communications link is established and maintained;
- the intended functions of the radio equipment which shall be in accordance with the documentation
accompanying the equipment;
- 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);
- information about ancillary equipment intended to be used with the radio equipment;
- an exhaustive list of ports, classified as either power or signal/control. Power ports shall further be classified as
AC or DC power;
- the humidity range, temperature, and supply voltage for all equipment submitted for testing.
5.2 Equipment which can provide a continuous communication
link
The test arrangement and signals, given in clause 4, apply to radio equipment or a combination of radio equipment and
ancillary equipment that permits the establishment of a communication link. The assessment of equipment performance
shall be based on speech call and data transfer according to the criteria in clause 6.
5.3 Equipment which can only provide a discontinuous
communication link (packet data/transmission)
If the equipment does not permit or allow for a communications link to be established and maintained during the EMC
tests (as in subclause 5.2), the manufacturer shall define the performance assessment. The manufacturer shall provide
the method of observing the degradation of performance of the equipment.
5.4 Equipment which does not provide a communication link
If the equipment is of a specialised nature which does not permit a communication link to be established, the
manufacturer shall define the method of test to determine the acceptable level of performance or degradation of
performance during and/or after the test. The manufacturer shall provide the method of observing the degradation of
performance of the equipment.
The performance assessment carried out shall be simple, but at the same time give adequate proof that the primary
functions of the equipment are operational.
5.5 Conformance of ancillary equipment
Ancillary equipment shall be tested with it connected to a UE in which case compliance shall be demonstrated to the
appropriate clauses of the present document.
