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 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 [5].

4.2 Relay classes

The Relay classes are defined based on the RF scenarios expected for the Relay access deployment, defined in terms of the Minimum Coupling Loss (MCL) between Relay and UE. The following definitions are used:

– High-CL Relay are characterised by requirements derived from outdoor Relay scenarios with a Relay to UE minimum coupling loss equals to 59 dB.

– Low-CL Relay are characterised by requirements derived from indoor Relay scenarios with a Relay to UE minimum coupling loss equals to 45 dB.

4.3 Regional requirements

Some requirements in the present document may only apply in certain regions either as optional requirements or set by local and regional regulation as mandatory requirements. It is normally not stated in the 3GPP specifications under what exact circumstances that the requirements apply, since this is defined by local or regional regulation.

Table 4.3-1 lists all requirements that may be applied differently in different regions.

Table 4.3-1: List of regional requirements

Clause number	Requirement	Comments
5.2	Operating bands	Some bands may be applied regionally.
5.3	Channel bandwidth	Some channel bandwidths may be applied regionally.
5.4	Channel arrangement	The requirement is applied according to what operating bands in clause 5.5 that are supported by the BS.
6.5.1	Transmitter spurious emissions	Some of the requirements references in this may be applied regionally. This is further detailed in TS 36.104 [3] subclause 4.3.
7.6.3	Blocking requirements for co-location	Some of the requirements references in this may be applied regionally. This is further detailed in TS 36.104 [3] subclause 4.3.
