A measurement
system for over-the-air testing of a device for non-terrestrial networks is described. The measurement
system includes an
anechoic chamber, at least one transmission antenna configured to transmit a source
signal, a
polarization rotator configured to rotate a polarization state of the source
signal transmitted by the transmission antenna, and an
electronic circuit configured to control the
polarization rotator such that an ionospheric Faraday rotation is simulated. In addition, a
user equipment (UE) is described. The UE is configured to measure a polarization direction of a received
signal and to report the measured polarization direction by transmitting it as
channel state information. Further, a method for emulating and determining a polarization mismatch in non-terrestrial communication systems is described. The method includes a step of establishing a connection between a
system simulator and a
device under test, wherein the system simulator indicates the used polarization to the
device under test.
