4 Essential requirements specification
With reference to article 3.2 of Directive 1999/5/EC [i.2] the phenomena in this clause have been identified as relevant
to the essential requirements.
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 at all times when operating within the boundary limits of the required operational
environmental profile.
4.2 Conformance requirements
This clause describes the conformance requirements for OFDMA TDD WMAN Base Stations.
4.2.1 Introduction
To meet the essential requirement under article 3.2 of the R&TTE Directive [i.2] for IMT Base Stations (BS) six
essential parameters in addition to those in EN 301 908-1 [1] have been identified. Table 4.2.1-1 provides a cross
reference between these six essential parameters and the corresponding nine technical requirements for equipment
within the scope of the present document.
To fulfil an essential parameter the compliance with all the corresponding technical requirements in table 4.2.1-1 must
be verified.

4.2.2 Transmitter Spectrum Emission Mask
4.2.2.1 Definition
The Transmitter 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 transmitting on a single RF carrier configured in accordance with the manufacturer's specification shall
meet the requirement.

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 the same filter pass band centred on a
first or second adjacent channel. The first adjacent and second adjacent channel centre offsets relative to the assigned
channel centre frequency are 5 MHz and 10 MHz when the nominal occupied channel bandwidth is 5 MHz. These
offsets are 10 MHz and 20 MHz respectively when the nominal occupied channel bandwidth is 10 MHz.
4.2.3.2 Limits
The requirements in tables 4.2.3.2.1-1 and 4.2.3.2.2-1 are based upon a measurement filter characteristic that is
rectangular with a width dependant upon the BS channel bandwidth.

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 is measured at the Base Station RF output port.
The spurious emission limits are specified in terms of general requirements in line with ITU-R Recommendation
SM.329-10 [i.7] and frequency range specific requirements to address inter-system co-existence.
4.2.4.2 Limits
4.2.4.2.1 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/REC 74-01 [2].
The following requirements in tables 4.2.4.2.1.1-1 and 4.2.4.2.1.2-1 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 centre carrier frequency. In the following fc is the center frequency of
transmit signal and f is the frequency of spurious emission.

4.2.5 Base station maximum output power
4.2.5.1 Definition
The maximum output power tolerance is the difference between the declared Pnom and the actual maximum output
power and corresponding tolerance limits.
4.2.5.2 Limits
The requirement shall apply to both Wide Area BS and Local Area BS.
In normal conditions, the measured output power, derived according to clause 5.4.4.1.2, shall remain within +2,7 dB
and -2,7 dB of the manufacturer's rated output power.

4.2.5.3 Conformance
Conformance tests described in clause 5.4.4 shall be carried out.
4.2.6 Transmit intermodulation
4.2.6.1 Definition
The transmit intermodulation performance is a measure of the capability of the transmitter to inhibit the generation of
signals in its non linear elements caused by presence of the wanted signal and an interfering signal reaching the
transmitter via the antenna.
The transmit intermodulation level is the power of the intermodulation products when a modulated interference signal is
injected into the antenna connector at a mean power level of 30 dB lower than that of the mean power of the wanted
signal. The wanted signal bandwidth shall be 5 MHz and 10 MHz respectively. The interferer has the same bandwidth
as the wanted signal.
For 5 MHz channel BW, the centre frequency of the interference signal offset from the subject signal carrier centre
frequency shall be at ±5 MHz, ±10 MHz, ±15 MHz (±10 MHz, ±20 MHz, ±30 MHz for 10 MHz channel BW) but
exclude interference frequencies that are partially or completely outside of the declared operating frequency band of the
base station.
4.2.6.2 Limits
rd
With the test signal applied, the spectrum emission mask, ACLR and spurious emission requirements at the specific 3
th
and 5 order intermodulation frequencies, excluding those overlapping the interfering signal, shall continue to meet the
limits in clauses 4.2.2, 4.2.3 and 4.2.4.
4.2.6.3 Conformance
Conformance tests described in clause 5.4.5 shall be carried out.
4.2.7 Receiver spurious emissions
4.2.7.1 Definition
The spurious emissions power is the power of emissions, generated or amplified in a receiver, which appear at the BS
antenna connector. The requirements apply to all BS with separate Rx and Tx antenna port. The test shall be performed
when both Tx and Rx are on with the Tx port terminated.
For BS equipped with only a single antenna connector for both transmitter and receiver, the requirements of clause 4.2.4
Transmitter spurious emissions shall apply to this port, and this test need not be performed.
The following requirements in table 4.2.7.2-1 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 centre carrier frequency.
4.2.7.2 Limits
The requirement shall apply to both Wide Area BS and Local Area BS.

4 Essential requirements specification
With reference to article 3.2 of Directive 1999/5/EC [i.2] the phenomena in this clause have been identified as relevant
to the essential requirements.
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 at all times when operating within the boundary limits of the required operational
environmental profile.
4.2 Conformance requirements
This clause describes the conformance requirements for OFDMA TDD WMAN Base Stations.
4.2.1 Introduction
To meet the essential requirement under article 3.2 of the R&TTE Directive [i.2] for IMT Base Stations (BS) six
essential parameters in addition to those in EN 301 908-1 [1] have been identified. Table 4.2.1-1 provides a cross
reference between these six essential parameters and the corresponding nine technical requirements for equipment
within the scope of the present document.
To fulfil an essential parameter the compliance with all the corresponding technical requirements in table 4.2.1-1 must
be verified.

4.2.2 Transmitter Spectrum Emission Mask
4.2.2.1 Definition
The Transmitter 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

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 the same filter pass band centred on a
first or second adjacent channel. The first adjacent and second adjacent channel centre offsets relative to the assigned
channel centre frequency are 5 MHz and 10 MHz when the nominal occupied channel bandwidth is 5 MHz. These
offsets are 10 MHz and 20 MHz respectively when the nominal occupied channel bandwidth is 10 MHz.
4.2.3.2 Limits
The requirements in tables 4.2.3.2.1-1 and 4.2.3.2.2-1 are based upon a measurement filter characteristic that is
rectangular with a width dependant upon the BS channel bandwidth.

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 is measured at the Base Station RF output port.
The spurious emission limits are specified in terms of general requirements in line with ITU-R Recommendation
SM.329-10 [i.7] and frequency range specific requirements to address inter-system co-existence.
4.2.4.2 Limits
4.2.4.2.1 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/REC 74-01 [2].
The following requirements in tables 4.2.4.2.1.1-1 and 4.2.4.2.1.2-1 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 centre carrier frequency. In the following fc is the center frequency of
transmit signal and f is the frequency of spurious emission.

4.2.6 Transmit intermodulation
4.2.6.1 Definition
The transmit intermodulation performance is a measure of the capability of the transmitter to inhibit the generation of
signals in its non linear elements caused by presence of the wanted signal and an interfering signal reaching the
transmitter via the antenna.
The transmit intermodulation level is the power of the intermodulation products when a modulated interference signal is
injected into the antenna connector at a mean power level of 30 dB lower than that of the mean power of the wanted
signal. The wanted signal bandwidth shall be 5 MHz and 10 MHz respectively. The interferer has the same bandwidth
as the wanted signal.
For 5 MHz channel BW, the centre frequency of the interference signal offset from the subject signal carrier centre
frequency shall be at ±5 MHz, ±10 MHz, ±15 MHz (±10 MHz, ±20 MHz, ±30 MHz for 10 MHz channel BW) but
exclude interference frequencies that are partially or completely outside of the declared operating frequency band of the
base station.
4.2.6.2 Limits
rd
With the test signal applied, the spectrum emission mask, ACLR and spurious emission requirements at the specific 3
th
and 5 order intermodulation frequencies, excluding those overlapping the interfering signal, shall continue to meet the
limits in clauses 4.2.2, 4.2.3 and 4.2.4.
4.2.6.3 Conformance
Conformance tests described in clause 5.4.5 shall be carried out.
4.2.7 Receiver spurious emissions
4.2.7.1 Definition
The spurious emissions power is the power of emissions, generated or amplified in a receiver, which appear at the BS
antenna connector. The requirements apply to all BS with separate Rx and Tx antenna port. The test shall be performed
when both Tx and Rx are on with the Tx port terminated.
For BS equipped with only a single antenna connector for both transmitter and receiver, the requirements of clause 4.2.4
Transmitter spurious emissions shall apply to this port, and this test need not be performed.
The following requirements in table 4.2.7.2-1 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 centre carrier frequency.
4.2.7.2 Limits
The requirement shall apply to both Wide Area BS and Local Area BS.
