Measurement system for over-the-air testing of a device for non-terrestrial networks, user equipment, and method for emulating and determining a polarization mismatch in non-terrestrial communication systems

Abstract

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.
