Abstract: The present disclosure provides a base station test system comprising a link signal acquisition interface configured to acquire a link signal from a device under test, wherein the device under test comprises at least part of a non-terrestrial-network access node, also called NTN access node, and a link signal processor coupled to the link signal acquisition interface, wherein the link signal processor is configured to determine at least one parameter for the device under test based on the acquired link signal. In addition, the present disclosure provides a respective method.

Abstract: A method of testing user equipment for non-terrestrial networks is described. The method includes, for example, the steps of: providing GNSS data and ephemeris data by a test system, wherein the GNSS data is associated with a position of a user equipment (UE) device of a non-terrestrial network, and wherein the ephemeris data is associated with a position of a satellite node of the non-terrestrial network; transmitting the GNSS data and the ephemeris data to the UE device; determining a timing advance and/or a Doppler pre-compensation shift by the UE device based on the GNSS data and the ephemeris data; generating an uplink signal by the UE device based on the determined timing advance and/or the determined Doppler pre-compensation shift; and analyzing the uplink signal by the test system in order to assess a performance of the UE device. Further, a test system for testing user equipment for non-terrestrial networks is described.

Abstract: A method of testing an Integrated Access Backhaul (IAB) node is disclosed, the method including: providing a device under test as well as a test equipment for testing the device under test, wherein the device under test corresponds to an Integrated Access Backhaul (IAB) node to be tested; simulating at least one Integrated Access Backhaul (IAB) donor by the test equipment; simulating a participant by the test equipment, the participant being connected with the device under test; establishing at least one connection between the device under test and the test equipment, wherein a backhaul link is established with the test equipment; configuring link resources for the device under test via configuration information by the test equipment; gathering reception information by the test equipment; and combining the configuration information with the reception information by the test equipment in order to verify correct resource utilization of the device under test.
