Abstract
A method for modeling an NR DUT using a MIMO OTA test system including a BTS configured to send and receive RF test signals to and from the DUT, and probes configured to reproduce a three-dimensional fading environment for the DUT placed in a quiet zone of an anechoic chamber in response to the RF test signals. The method includes building CIR files for fading channels provided by a channel emulator in the MIMO OTA test system; selecting preferred CIR files from the CIR files having corresponding channel power levels higher than a threshold corresponding to a minimum power level; and performing bi-directional fading emulation with the fading channels using the preferred CIR files, where remaining CIR files are disregarded. The probes reproduce the three-dimensional fading environment for the DUT in the quiet zone using the RF test signals adjusted by the bi-directional fading emulation with the fading channels.
