D.2.4 Receiver spurious emissions

TAB connector(s) may be connected to the measurement equipment singularly and tested one at a time (figure D.2.2-1), or may be tested simultaneously in groups (figure D.2.2-2) where the group size may range from 2 to all the TAB connectors.

In all cases the measurement is per TAB connector but the measurement may be done in parallel.

D.3 IAB type 1-H performance requirements

D.3.1 Performance requirements for PUSCH and PUCCH on single antenna port in multipath fading conditions

Figure D.3.1-1: Functional set-up for performance requirements for PUSCH and PUCCH for IAB with Rx diversity (2 Rx case shown)

NOTE 1: The feedback could be done as an RF feedback, either using NR channels or using other means, or as a digital feedback. The HARQ Feedback should be error free.

NOTE 2: In tests performed with signal generators, a synchronization signal may be provided between the IAB node and the signal generator, or a common (e.g., GNSS) source may be provided to both IAB node and the signal generator, to enable correct timing of the wanted signal. The method of synchronization with the TE is left to test implementation.

NOTE 3: It is left up to implementation how L1/L2 is configured for testing.
