4 Technical requirements specifications
4.1 Environmental profile
The technical requirements of the present document apply under the environmental profile for operation of the
equipment, which shall be declared by the manufacturer. The equipment shall comply with all the technical
requirements of the present document, which are identified as applicable in annex A, at all times when operating within
the boundary limits of the declared operational environmental profile.
The operational environmental profile declared by the manufacturer shall at least contain all test environments specified
throughout clause 5 of the present document.
4.2 Conformance requirements
4.2.1 Introduction
The requirements in the present document are based on the assumption that the operating band (see table 1-1) is shared
between systems of the IMT family (for band 3 and 8 also GSM) or systems having compatible characteristics.
To meet the essential requirement under article 3.2 of Directive 2014/53/EU [i.1] for IMT Repeaters, a set of essential
parameters in addition to those in ETSI EN 301 908-1 [i.3] have been identified. Table 4.2.1-1 provides a cross
reference between these essential parameters and the corresponding technical requirements for equipment within the
scope of the present document.

NOTE: Some of the essential parameters of the ETSI EG 203 336 [i.2] are not included into the present document
since those requirements are not applicable for repeater equipment.
The manufacturer shall declare operating band(s) for the Repeater. The technical requirements in the present document
apply for the declared operating band(s) as outlined for each requirement. For a Repeater supporting more than one
operating band, conformance testing for each technical requirement in clause 5 shall be performed.
The technical requirements also apply to Repeater configurations described in annex B.
4.2.2 Operating band unwanted emissions
4.2.2.1 Definition
Unwanted emissions consist of out of band emissions and spurious emissions (Recommendation ITU-R
SM.329-12 [i.6]). Out of band emissions are emissions immediately outside the pass band bandwidth resulting from the
modulation process and non-linearity in the transmitter, but excluding spurious emissions. Spurious emissions are
emissions which are caused by unwanted transmitter effects such as harmonics emission, parasitic emission,
intermodulation products and frequency conversion products, but exclude out of band emissions.
ETSI
12 Draft ETSI EN 301 908-15 V15.0.1 (2019-09)
The out of band emissions requirement for repeater is specified both in terms operating band unwanted emissions and
protection of the BS receiver in the uplink operating band. The operating band unwanted emissions define all unwanted
emissions in the repeater operating band plus the frequency ranges 10 MHz above and 10 MHz below that band.
Unwanted emissions outside of this frequency range are limited by a spurious emissions requirement.
4.2.2.2 Limit
4.2.2.2.0 General
Emissions shall not exceed the maximum levels specified in the tables below, where:
• Δf is the separation between the nominal pass band edge frequency and the nominal -3 dB point of the
measuring filter closest to the carrier frequency.
• Nominal passband edge is the lowest and highest frequency of the pass band of the repeater.
• BW is the measurement bandwidth.
Meas
• BW is the bandwidth of the repeaters pass band.
Pass band
• f_offset is the separation between the nominal pass band edge frequency and the centre of the measuring filter.
• f_offset is the offset to the frequency 10 MHz outside the repeater operating band.
max
• Δf is equal to f_offset minus half of the bandwidth of the measuring filter.
max max
Unless otherwise stated, all requirements are measured as mean power (RMS).
This requirement applies to the uplink and downlink of the repeater, at maximum gain, and with the following input
signals:
• without E-UTRA input signal;
• with E-UTRA input signals in the pass band of the repeater, at levels that produce the maximum rated power
output per channel;
• with 10 dB increased E-UTRA input signals in all channels in the pass band, compared to the input level
producing the maximum rated output power.
4.2.2.2.1 General operating band unwanted emissions

For the purposes of the present document, the following terms apply:
carrier: modulated waveform conveying the E-UTRA or UTRA (WCDMA) physical channels
ETSI
9 ETSI EN 301 908-15 V15.1.1 (2020-01)
channel bandwidth: RF bandwidth supporting a single E-UTRA RF carrier with the transmission bandwidth
configured in the uplink or downlink of a cell
NOTE: The channel bandwidth is measured in MHz and is used as a reference for transmitter and receiver RF
requirements.
channel edge: lowest and highest frequency of the E-UTRA carrier, separated by the channel bandwidth
donor coupling loss: coupling loss between the repeater and the donor Base Station
downlink: signal path where Base Station transmits and mobile receives
downlink operating band: part of the operating band designated for downlink
nominal passband edge: lowest and highest frequency of the pass band of the repeater
operating band: frequency range that is defined with a specific set of technical requirements, in which E-UTRA FDD
operates
NOTE: The operating band(s) for an E-UTRA Repeater is declared by the manufacturer according to the
designations in clause 1, table 1-1. Operating bands for UTRA are designated with Roman numerals,
while the corresponding operating bands for E-UTRA are designated with Arabic numerals. Unless
specified, operating band refers to the uplink operating band and downlink operating band.
output power, Pout: mean power of one carrier at maximum repeater gain delivered to a load with resistance equal to
the nominal load impedance of the transmitter
pass band: frequency range that the repeater operates in with operational configuration
NOTE: This frequency range can correspond to one or several consecutive channels. If they are not consecutive
each subset of channels is considered as an individual pass band. The Repeater can have one or several
pass bands.
rated output power: rated output power of the repeater is the mean power level per carrier that the manufacturer has
declared to be available at the antenna connector
repeater: device that receives, amplifies and transmits the radiated or conducted RF carrier both in the downlink
direction (from the Base Station to the mobile area) and in the uplink direction (from the mobile to the Base Station)
NOTE: In operating bands specified with only down-link or up-link, only the up-link or down-link as specified
for the operating band is repeated.
transmission bandwidth: bandwidth of an instantaneous transmission from a UE or BS, measured in Resource Block
units
transmission bandwidth configuration: highest transmission bandwidth allowed for uplink or downlink in a given
channel bandwidth, measured in Resource Block units
uplink: signal path where mobile transmits and Base Station receives

4 Technical requirements specifications
4.1 Environmental profile
The technical requirements of the present document apply under the environmental profile for operation of the
equipment, which shall be declared by the manufacturer. The equipment shall comply with all the technical
requirements of the present document, which are identified as applicable in annex A, at all times when operating within
the boundary limits of the declared operational environmental profile.
The operational environmental profile declared by the manufacturer shall at least contain all test environments specified
throughout clause 5 of the present document.
4.2 Conformance requirements
4.2.1 Introduction
The requirements in the present document are based on the assumption that the operating band (see table 1-1) is shared
between systems of the IMT family (for band 3 and 8 also GSM) or systems having compatible characteristics.
To meet the essential requirement under article 3.2 of Directive 2014/53/EU [i.1] for IMT Repeaters, a set of essential
parameters in addition to those in ETSI EN 301 908-1 [i.3] have been identified. Table 4.2.1-1 provides a cross
reference between these essential parameters and the corresponding technical requirements for equipment within the
scope of the present document.

NOTE: Some of the essential parameters of the ETSI EG 203 336 [i.2] are not included into the present document
since those requirements are not applicable for repeater equipment.
The manufacturer shall declare operating band(s) for the Repeater. The technical requirements in the present document
apply for the declared operating band(s) as outlined for each requirement. For a Repeater supporting more than one
operating band, conformance testing for each technical requirement in clause 5 shall be performed.
The technical requirements also apply to Repeater configurations described in annex B.
4.2.2 Operating band unwanted emissions
4.2.2.1 Definition
Unwanted emissions consist of out of band emissions and spurious emissions (Recommendation ITU-R
SM.329-12 [i.6]). Out of band emissions are emissions immediately outside the pass band bandwidth resulting from the
modulation process and non-linearity in the transmitter, but excluding spurious emissions. Spurious emissions are
emissions which are caused by unwanted transmitter effects such as harmonics emission, parasitic emission,
intermodulation products and frequency conversion products, but exclude out of band emissions.
ETSI
12 ETSI EN 301 908-15 V15.1.1 (2020-01)
The out of band emissions requirement for repeater is specified both in terms operating band unwanted emissions and
protection of the BS receiver in the uplink operating band. The operating band unwanted emissions define all unwanted
emissions in the repeater operating band plus the frequency ranges 10 MHz above and 10 MHz below that band.
Unwanted emissions outside of this frequency range are limited by a spurious emissions requirement.
4.2.2.2 Limit
4.2.2.2.0 General
Emissions shall not exceed the maximum levels specified in the tables below, where:
• Δf is the separation between the nominal pass band edge frequency and the nominal -3 dB point of the
measuring filter closest to the carrier frequency.
• Nominal passband edge is the lowest and highest frequency of the pass band of the repeater.
• BW is the measurement bandwidth.
Meas
• BW is the bandwidth of the repeaters pass band.
Pass band
• f_offset is the separation between the nominal pass band edge frequency and the centre of the measuring filter.
• f_offset is the offset to the frequency 10 MHz outside the repeater operating band.
max
• Δf is equal to f_offset minus half of the bandwidth of the measuring filter.
max max
Unless otherwise stated, all requirements are measured as mean power (RMS).
This requirement applies to the uplink and downlink of the repeater, at maximum gain, and with the following input
signals:
• without E-UTRA input signal;
• with E-UTRA input signals in the pass band of the repeater, at levels that produce the maximum rated power
output per channel;
• with 10 dB increased E-UTRA input signals in all channels in the pass band, compared to the input level
producing the maximum rated output power.
4.2.2.2.1 General operating band unwanted emissions
For E-UTRA FDD repeater operating in bands 1, 3, 8 or 32 emissions shall not exceed the maximum levels specified in
tables 4.2.2.2.1-1 and 4.2.2.2.1-2. The measurements shall apply to both paths uplink and downlink of the Repeater.

4 Technical requirements specifications
4.1 Environmental profile
The technical requirements of the present document apply under the environmental profile for operation of the
equipment, which shall be declared by the manufacturer. The equipment shall comply with all the technical
requirements of the present document, which are identified as applicable in annex A, at all times when operating within
the boundary limits of the declared operational environmental profile.
The operational environmental profile declared by the manufacturer shall at least contain all test environments specified
throughout clause 5 of the present document.
4.2 Conformance requirements
4.2.1 Introduction
The requirements in the present document are based on the assumption that the operating band (see table 1-1) is shared
between systems of the IMT family (for band 3 and 8 also GSM) or systems having compatible characteristics.
To meet the essential requirement under article 3.2 of Directive 2014/53/EU [i.1] for IMT Repeaters, a set of essential
parameters in addition to those in ETSI EN 301 908-1 [i.3] have been identified. Table 4.2.1-1 provides a cross
reference between these essential parameters and the corresponding technical requirements for equipment within the
scope of the present document.

NOTE: Some of the essential parameters of the ETSI EG 203 336 [i.2] are not included into the present document
since those requirements are not applicable for repeater equipment.
The manufacturer shall declare operating band(s) for the Repeater. The technical requirements in the present document
apply for the declared operating band(s) as outlined for each requirement. For a Repeater supporting more than one
operating band, conformance testing for each technical requirement in clause 5 shall be performed.
The technical requirements also apply to Repeater configurations described in annex B.
4.2.2 Operating band unwanted emissions
4.2.2.1 Definition
Unwanted emissions consist of out of band emissions and spurious emissions (Recommendation ITU-R
SM.329-12 [i.6]). Out of band emissions are emissions immediately outside the pass band bandwidth resulting from the
modulation process and non-linearity in the transmitter, but excluding spurious emissions. Spurious emissions are
emissions which are caused by unwanted transmitter effects such as harmonics emission, parasitic emission,
intermodulation products and frequency conversion products, but exclude out of band emissions.
ETSI
12 ETSI EN 301 908-15 V15.1.1 (2020-01)
The out of band emissions requirement for repeater is specified both in terms operating band unwanted emissions and
protection of the BS receiver in the uplink operating band. The operating band unwanted emissions define all unwanted
emissions in the repeater operating band plus the frequency ranges 10 MHz above and 10 MHz below that band.
Unwanted emissions outside of this frequency range are limited by a spurious emissions requirement.
4.2.2.2 Limit
4.2.2.2.0 General
Emissions shall not exceed the maximum levels specified in the tables below, where:
• Δf is the separation between the nominal pass band edge frequency and the nominal -3 dB point of the
measuring filter closest to the carrier frequency.
• Nominal passband edge is the lowest and highest frequency of the pass band of the repeater.
• BW is the measurement bandwidth.
Meas
• BW is the bandwidth of the repeaters pass band.
Pass band
• f_offset is the separation between the nominal pass band edge frequency and the centre of the measuring filter.
• f_offset is the offset to the frequency 10 MHz outside the repeater operating band.
max
• Δf is equal to f_offset minus half of the bandwidth of the measuring filter.
max max
Unless otherwise stated, all requirements are measured as mean power (RMS).
This requirement applies to the uplink and downlink of the repeater, at maximum gain, and with the following input
signals:
• without E-UTRA input signal;
• with E-UTRA input signals in the pass band of the repeater, at levels that produce the maximum rated power
output per channel;
• with 10 dB increased E-UTRA input signals in all channels in the pass band, compared to the input level
producing the maximum rated output power.
4.2.2.2.1 General operating band unwanted emissions
For E-UTRA FDD repeater operating in bands 1, 3, 8 or 32 emissions shall not exceed the maximum levels specified in
tables 4.2.2.2.1-1 and 4.2.2.2.1-2. The measurements shall apply to both paths uplink and downlink of the Repeater.
