OTA test requirements specific and OTA measurement chamber specific calibration (and measurement) procedures were captured in TR 37.941 [25] for the following requirements sets:

– TX and Rx directional requirements

– In-band and out-of-band TRP requirements

– Co-location requirements

– In-band and out-of-band blocking requirements

All the calibrations procedures in TR 37.941 [25] for the BS are assumed to be also applicable to IAB type 1-H and IAB type 1-O for the FR1 frequency range (i.e. up to 6 GHz), as well as for IAB type 2-O for the FR2 frequency range, unless stated otherwise.
