4.3.1 IAB-DU class

The requirements in the present document apply to Wide Area IAB-DU, Medium Range IAB-DU and Local Area IAB-DU unless otherwise stated. The associated deployment scenarios for each class are exactly the same for IAB-DU with and without connectors.

For IAB type 1-O and 2-O, IAB-DU classes are defined as indicated below:

– Wide Area IAB-DU are characterised by requirements derived from Macro Cell scenarios with a BS to UE minimum distance along the ground equal to 35 m.

– Medium Range IAB-DU are characterised by requirements derived from Micro Cell scenarios with a BS to UE minimum distance along the ground equal to 5 m.

– Local Area IAB-DU are characterised by requirements derived from Pico Cell scenarios with a BS to UE minimum distance along the ground equal to 2 m.

The manufacturer shall declare the intended class of the IAB under test.

4.3.2 IAB-MT class

The requirements in the present document apply to Wide Area IAB-MT and Local Area IAB-MT classes unless otherwise stated.

For IAB type 1-O, and IAB type 2-O, IAB-MT classes are defined as indicated below:

– Wide Area IAB-MT are characterised by requirements derived from Macro Cell and/or Micro Cell scenarios.

– Local Area IAB-MT are characterised by requirements derived from Pico Cell and /or Micro Cell scenarios.
