4.1 Relationship between Minimum Requirements and Test Requirements
The Minimum Requirements given in this specification make no allowance for measurement uncertainty. The test specification 25.141 section 4 defines Test Tolerances. These Test Tolerances are individually calculated for each test. The Test Tolerances are used to relax the Minimum Requirements in this specification to create Test Requirements.
The measurement results returned by the Test System are compared – without any modification – against the Test Requirements as defined by the shared risk principle.
The Shared Risk principle is defined in ITU-R M.1545.
4.2 Base station classes
The requirements in this specification apply to Wide Area Base Stations, Medium Range Base Stations, Local Area Base Stations and Home Base Stations unless otherwise stated.
Wide Area Base Stations are characterised by requirements derived from Macro Cell scenarios with a BS to UE minimum coupling loss equal to 70 dB. The Wide Area Base Station class has the same requirements as the base station for General Purpose application in Release 99, 4 and 5.
Medium Range Base Stations are characterised by requirements derived from Micro Cell scenarios with a BS to UE minimum coupling loss equal to 53 dB.
Local Area Base Stations are characterised by requirements derived from Pico Cell scenarios with a BS to UE minimum coupling loss equal to 45 dB.
Home Base Stations are characterised by requirements derived from Femto Cell scenarios.
4.3 Regional requirements

4.4 Environmental requirements for the BS equipment
The BS equipment shall fulfil all the requirements in the full range of environmental conditions for the relevant environmental class from the relevant IEC specifications listed below
60 721-3-3 "Stationary use at weather protected locations"
60 721-3-4 "Stationary use at non weather protected locations"
Normally it should be sufficient for all tests to be conducted using normal test conditions except where otherwise stated. For guidance on the use of test conditions to be used in order to show compliance refer to TS 25.141.
4.5 Applicability of requirements
For BS that is UTRA (single-RAT) capable only, the requirements in the present document are applicable and additional conformance to TS 37.104 [10] is optional. For a BS additionally conforming to TS 37.104 [10], conformance to some of the RF requirements in the present document can be demonstrated through the corresponding requirements in TS 37.104 [10] as listed in Table 4.2.

4.6 Requirements for contiguous and non-contiguous spectrum
A spectrum allocation where the BS operates can either be contiguous or non-contiguous. Unless otherwise stated, the requirements in the present specification apply for BS configured for both contiguous spectrum operation and non-contiguous spectrum operation.
For BS operation in non-contiguous spectrum, some requirements apply also inside the sub-block gaps. For each such requirement, it is stated how the limits apply relative to the sub-block edges.
4.7 Requirements for BS capable of multi-band operation
For BS capable of multi-band operation, the RF requirements in clause 6 and 7 apply for each supported operating band unless otherwise stated. For some requirements it is explicitly stated that specific additions or exclusions to the requirement apply for BS capable of multi-band operation.
For BS capable of multi-band operation, various structures in terms of combinations of different transmitter and receiver implementations (multi-band or single band) with mapping of transceivers to one or more antenna port(s) in different ways are possible. In the case where multiple bands are mapped on separate antenna connectors, the following applies:
– Single-band transmitter spurious emissions, spectrum emission mask, ACLR, transmitter intermodulation and receiver spurious emissions requirements apply to each antenna connector.
– If the BS is configured for single-band operation, single-band requirements shall apply to the antenna connector configured for single-band operation and no exclusions or provisions for multi-band capable BS are applicable. Single-band requirements are tested separately at the antenna connector configured for single-band operation, with all other antenna connectors terminated.
