3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in the Radio Equipment Directive
2014/53/EU [i.2] and the following apply:
burst: period during which radio waves are intentionally transmitted, preceded and succeeded by periods during which
no intentional transmission is made
environmental profile: declared range of environmental conditions under which equipment within the scope of the
present document is required to be compliant
Eval_BW1: test condition where the pass band of a rectangular filter with a bandwidth of 4,75 MHz for 5 MHz
equipment and 9,5 MHz for 10 MHz equipment is used for measurement centred on an operating channel or a victim
channel
integral antenna: antenna which is declared to be part of the radio equipment by the supplier
NOTE: Even when equipment with an integral antenna is concerned, it might still be possible to separate the
antenna from the equipment using a special tool. In such cases the assessment of the radio equipment and
of the antenna against requirements of this multi-part deliverable may be done separately.
maximum output power: mean power level per carrier of the base station or user equipment measured at the antenna
connector in a specified reference condition
mean power: power (transmitted or received) in a bandwidth, when applied to a modulated signal
NOTE: The term "mean" here is used to exclude the amplitude fluctuation related to those theoretical variations
present in signal for example due to amplitude modulation, pulse shaping, pre-equalization, etc. Time
averaging should be applied to estimate mean power with the effect of the theoretical variations. The duty
cycle corresponding to burst activity within a frame should be also incorporated for "mean" power
estimation.

4.2.2 Spectrum emission mask
4.2.2.1 Definition
Spectrum emission mask defines an out of band emission requirement for the transmitter. These out of band emissions
are unwanted emissions outside the channel bandwidth resulting from the modulation process and non-linearity in the
transmitter but excluding spurious emissions.
4.2.2.2 Limits
A Base Station device transmitting on a single RF carrier configured in accordance with the manufacturer's
specification shall meet the requirement. Emissions shall not exceed the maximum level specified in tables 4.2.2.2.1-1
and 4.2.2.2.2-1 for the appropriate BS maximum output power and nominal channel bandwidths of 5 MHz and 10 MHz.
4.2.2.2.1 Requirements for 5 MHz channel bandwidth
The out-of-channel emission is specified as power level measured over the specified measurement bandwidth but
relative to dBc centred in the 5 MHz channel.
The power of any BS emission shall not exceed the levels specified in table 4.2.2.2.1-1.
Table 4.2.2.2.1-1: Spectrum emission mask requirement

3 3,5 to < 4,0 30 -26
4 7,5 to ≤ 12,5 1 000 -13
4.2.2.2.2 Requirements for 10 MHz channel bandwidth
The out-of-channel emission is specified as a power level relative to dBc centred in the 10 MHz channel.
The power of any BS emission shall not exceed the levels specified in table 4.2.2.2.2-1.
Table 4.2.2.2.2-1: Spectrum emission mask requirement
Segment Integration Allowed emission level within the
Offset Δf from channel centre
number (MHz) bandwidth integration bandwidth

1 5,0 to < 5,2 30 -14
2 5,2 to < 6,0 30 -14 - 15 (∆f - 2,715)
3 6,0 to < 6,5 30 -26
4 6,5 to < 15,0 1 000 -13
1 000 -15
5 15,0 to ≤ 25,0
NOTE: As an exception, in the band 925 MHz to 960 MHz, the maximum extent to which the emission mask
Segment 5 extends above the downlink band is limited to +10 MHz outside the upper downlink band
edge. Beyond this point, the spurious emission requirements of clause 4.2.4 shall be applied.
4.2.2.3 Conformance
Conformance tests described in clause 5.4.1 shall be carried out.
4.2.3 Transmitter Adjacent Channel Leakage power Ratio (ACLR)
4.2.3.1 Definition
Adjacent Channel Leakage power Ratio (ACLR) is the ratio of the mean power measured through a filter pass band
centred on the assigned channel frequency to the mean power measured through a filter pass band centred on the first
adjacent channel. The filter pass band, response and nominal bandwidth are set according to Eval_BW 1.

4.2.4 Transmitter spurious emissions
4.2.4.1 Definition
Transmitter 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. This conducted measurement is measured at the RF output port. The spurious emission limits are specified in
terms of general requirements in line with Recommendation ITU-R SM.329-10 [i.1] and frequency range specific
requirements to address inter-system co-existence.
4.2.4.2 Limits
4.2.4.2.0 General requirements
The requirements shall apply to both Wide Area BS and Local Area BS.
The limits of spurious emissions (or more precisely, according latest ITU-R definitions, unwanted emissions in the
spurious domain), shall conform to CEPT/ERC/Recommendation 74-01 [2].
The following requirements in tables 4.2.4.2.1-1, 4.2.4.2.2-1 and 4.2.4.2.3-1 are only applicable for frequencies, which
are greater than 250 % of the channel bandwidth (that is 12,5 MHz for the 5 MHz channel bandwidth and 25 MHz for
the 10 MHz channel bandwidth) away from the carrier centre frequency. In the following f is the centre frequency of
c
transmit signal and f is the frequency of spurious emission. BW is the channel bandwidth of choice, i.e. 5 MHz or
10 MHz.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in the Radio Equipment Directive
2014/53/EU [i.2] and the following apply:
burst: period during which radio waves are intentionally transmitted, preceded and succeeded by periods during which
no intentional transmission is made
environmental profile: declared range of environmental conditions under which equipment within the scope of the
present document is required to be compliant
Eval_BW1: test condition where the pass band of a rectangular filter with a bandwidth of 4,75 MHz for 5 MHz
equipment and 9,5 MHz for 10 MHz equipment is used for measurement centred on an operating channel or a victim
channel
integral antenna: antenna which is declared to be part of the radio equipment by the manufacturer
NOTE: Even when equipment with an integral antenna is concerned, it might still be possible to separate the
antenna from the equipment using a special tool. In such cases the assessment of the radio equipment and
of the antenna against requirements of this multi-part deliverable may be done separately.
maximum output power: mean power level per carrier of the base station or user equipment measured at the antenna
connector in a specified reference condition
ETSI
9 ETSI EN 301 908-22 V6.1.1 (2016-07)
mean power: power (transmitted or received) in a bandwidth, when applied to a modulated signal
NOTE: The term "mean" here is used to exclude the amplitude fluctuation related to those theoretical variations
present in signal for example due to amplitude modulation, pulse shaping, pre-equalization, etc. Time
averaging should be applied to estimate mean power with the effect of the theoretical variations. The duty
cycle corresponding to burst activity within a frame should be also incorporated for "mean" power
estimation.
nominal maximum output power: maximum nominal mean power level measured over total allocated channel
bandwidth of the Base Station available at the antenna connector declared by the manufacturer; for equipment
implementing dynamic change of modulation format, it is intended as the maximum nominal mean power associated to
the modulation format delivering the highest power
receiver thermal noise power: equal to k×T×BW×F
TM
WiMAX : trademarked name for the OFDMA TDD WMAN IMT technology

4.2.2 Spectrum emission mask
4.2.2.1 Definition
Spectrum emission mask defines an out of band emission requirement for the transmitter. These out of band emissions
are unwanted emissions outside the channel bandwidth resulting from the modulation process and non-linearity in the
transmitter but excluding spurious emissions.
4.2.2.2 Limits
A Base Station device transmitting on a single RF carrier configured in accordance with the manufacturer's
specification shall meet the requirement. Emissions shall not exceed the maximum level specified in tables 4.2.2.2.1-1
and 4.2.2.2.2-1 for the appropriate BS maximum output power and nominal channel bandwidths of 5 MHz and 10 MHz.
4.2.2.2.1 Requirements for 5 MHz channel bandwidth
The out-of-channel emission is specified as power level measured over the specified measurement bandwidth but
relative to dBc centred in the 5 MHz channel.
The power of any BS emission shall not exceed the levels specified in table 4.2.2.2.1-1.

4.2.4 Transmitter spurious emissions
4.2.4.1 Definition
Transmitter 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. This conducted measurement is measured at the RF output port. The spurious emission limits are specified in
terms of general requirements in line with Recommendation ITU-R SM.329-10 [i.1] and frequency range specific
requirements to address inter-system co-existence.
4.2.4.2 Limits
4.2.4.2.0 General requirements
The requirements shall apply to both Wide Area BS and Local Area BS.
The limits of spurious emissions (or more precisely, according latest ITU-R definitions, unwanted emissions in the
spurious domain), shall conform to CEPT/ERC/Recommendation 74-01 [2].
The following requirements in tables 4.2.4.2.1-1, 4.2.4.2.2-1 and 4.2.4.2.3-1 are only applicable for frequencies, which
are greater than 250 % of the channel bandwidth (that is 12,5 MHz for the 5 MHz channel bandwidth and 25 MHz for
the 10 MHz channel bandwidth) away from the carrier centre frequency. In the following f is the centre frequency of
c
transmit signal and f is the frequency of spurious emission. BW is the channel bandwidth of choice, i.e. 5 MHz or
10 MHz.

This conducted measurement is measured at the RF output port. The spurious emission limits are specified in terms of general requirements in line with Recommendation ITU-R SM.329-10 [i.1] and frequency range specific requirements to address inter-system co-existence. 4.2.4.2 Limits 4.2.4.2.0 General requirements The requirements shall apply to both Wide Area BS and Local Area BS. The limits of spurious emissions (or more precisely, according latest ITU-R definitions, unwanted emissions in the spurious domain), shall conform to CEPT/ERC/Recommendation 74-01 [2]. The following requirements in tables 4.2.4.2.1-1, 4.2.4.2.2-1 and 4.2.4.2.3-1 are only applicable for frequencies, which are greater than 250 % of the channel bandwidth (that is 12,5 MHz for the 5 MHz channel bandwidth and 25 MHz for the 10 MHz channel bandwidth) away from the carrier centre frequency. In the following fc is the centre frequency of transmit signal and f is the frequency of spurious emission. BW is the channel bandwidth of choice, i.e. 5 MHz or 10 MHz. 4.2.4.2.1 Requirements for 5 MHz channel bandwidth Table 4.2.4.2.1-1: Spurious Emission requirement for 5 MHz channel bandwidth Segment Frequency Range Measurement Bandwidth Maximum allowed level (dBm) 1 9 kHz ≤ f < 150 kHz 1 kHz -36 2 150 kHz ≤ f < 30 MHz 10 kHz -36 3 30 MHz ≤ f < 1 000 MHz 100 kHz -36 4 1 GHz ≤ f < 12,75 GHz 30 kHz If 12,5 MHz ≤ |fc-f| < 50 MHz 300 kHz If 50 MHz ≤ |fc-f| < 60 MHz 1 MHz If 60 MHz ≤ |fc-f| -30
