B.2.6 Enhanced IFF

38.508-13GPP5GSPart 1: Common test environmentRelease 17TSUser Equipment (UE) conformance specification

B.2.6.1 Description

The Enhanced IFF method utilizing multiple compact antenna test ranges (CATRs) creates the far field environment using a transformation with 2 or more parabolic reflectors for RRM testing with two simultaneously active AoA (NMAX_AoAs = 2) as defined in Clause 7.1.3.

An example RRM baseline system using an Enhanced IFF setup are shown in Figure B.2.6.1-1. Implementations of the RRM baseline system with only a subset of the reflectors/probes are possible as long as the system can satisfy the relative angular relationships outlined in Clause 7.1.3.2.1.

The key aspects of this test method setup are the same as the IFF setup, outlined in Clause B.2.4.1.

B.2.6.2 Quiet zone dimension

Same as Clause B.2.2.2.

B.2.6.3 Quality of the quiet zone

Same as Clause B.2.2.3.

B.2.6.4 Measurement Distance

Same as Clause B.2.4.4.
