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 shall
be verified.

There are EC and ECC Decisions for the harmonisation of certain frequency bands for terrestrial systems capable of
providing electronic communications services, including technical conditions and parameters related to spectrum usage
of the bands. These are related to the deployment and installation of the equipment, but are not related to the conformity
of the equipment with the present document.
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.

4.2.3 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, 4.2.3.2.1-2, 4.2.3.2.2-1 and 4.2.3.2.2-2 are based upon a measurement filter
characteristic that is rectangular with a width dependent upon the BS channel bandwidth and the BCI.
The requirements in tables 4.2.3.2.1-3 and 4.2.3.2.2-3 are based upon an adjacent channel measurement filter
characteristic that is RRC with a roll off factor of 0,22 and a width dependent upon the UE channel bandwidth.
The measurement bandwidth for the on-channel power is:
• 4,75 MHz for a 5 MHz channelized system;
• 9,5 MHz for a 10 MHz channelized system.

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
Recommendation ITU-R SM.329-12 [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].

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.

providing electronic communications services, including technical conditions and parameters related to spectrum usage
of the bands. These are related to the deployment and installation of the equipment, but are not related to the conformity
of the equipment with the present document.
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.

4.2.3 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, 4.2.3.2.1-2, 4.2.3.2.2-1 and 4.2.3.2.2-2 are based upon a measurement filter
characteristic that is rectangular with a width dependent upon the BS channel bandwidth and the BCI.
The requirements in tables 4.2.3.2.1-3 and 4.2.3.2.2-3 are based upon an adjacent channel measurement filter
characteristic that is RRC with a roll off factor of 0,22 and a width dependent upon the UE channel bandwidth.
The measurement bandwidth for the on-channel power is:
• 4,75 MHz for a 5 MHz channelized system;
• 9,5 MHz for a 10 MHz channelized system.

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
Recommendation ITU-R SM.329-12 [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].
