Abstract: A test system for testing performance of a multi-link communication system including at least one non-terrestrial network (NTN) communication link. The system comprises an encoding and compression stage to process transmission data at a signal transmission side of the test system by emulating different encoding and compression schemes to provide encoded and compressed transmission data converted into radio frequency, RF, signals transferred via communication links of the communication system to a terrestrial wireless device at a signal reception side of the test system. The system further comprises a decoding and decompression stage to apply corresponding decoding and decompression schemes to sampled RF signals to provide reception data at the signal reception side of the system and a data analysing unit adapted to analyse a performance of the communication system by evaluating the reception data provided by the decoding and decompression stage of the system.

Abstract: Embodiments of the present disclosure provide a method of operating an internet-of-things (IoT) device. An internet-of-things device with an energy storage is provided. An energy harvesting signal is transmitted over-the-air. The energy harvesting signal provides energy to be stored in the energy storage. The energy harvesting signal is transmitted prior to a synchronization signal which synchronizes the internet-of-things device.

Abstract: A system for testing a real time application for synchronized user equipment is provided. The system comprises a first UE and a second UE. The first UE and the second UE are configured to exchange information as part of executing the real time application. The system further comprises a network simulator. The network simulator is configured to test, if the first UE and the second UE exchange and/or process the information according to a latency requirement. The information is exchanged between the first UE and the second UE by means of uplink communication, downlink communication, and/or sidelink communication.

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.

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.
