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 NR 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 manufacturer's 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, methods of measurement, frequency ranges, applicable
limits and minimum performance criteria for all types of NR UE(s) and their accessories]. NR 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. NR base station equipment operating within network infrastructure is covered by the technical specification TS
38.113 [2].
[Requirements for the radiated emission from the enclosure port of integral antenna equipment and ancillaries are
included in the present document. Technical specifications for conducted emissions from the antenna connector are
found in the 3GPP specifications for the radio interface, e.g. TS 38.xyz, for the effective use of the radio spectrum.]
Requirements for the radiated emissions from the enclosure port and ancillaries cover two cases:
- [UE equipment supporting operations in a frequency range for which antenna connectors are available (i.e. for
operations in Frequency Range 1 as defined in e.g. TS 38.101-1 [3] for the radio interface)]
- [UE equipment supporting operations in a frequency range for which only integral antennas may be available
(i.e. for operations in Frequency Range 2 as defined in e.g. TS 38.101-2 [4] for the radio interface)]
The immunity requirements are 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.
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.

3.1 Definitions
For the purposes of the present document, the terms and definitions given in 3GPP 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 3GPP
TR 21.905 [1].

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).
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.]
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.
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.
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.
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.
Spurious emission from ITU-R SM 329 [5]: 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,
