Testing framework for ue timing-tracking capabilities over satellite or similar communications

The method as in claim 105, further comprising feeding the user equipment with position information by emulating a global satellite navigation system including its values, wherein the values fed by feeding the user equipment with position information by emulating the global satellite navigation system are performed by one of the following:

• a) the values are generated by recording of global satellite navigation system signals received by actual devices in field conditions;
• b) the values are created via a computer algorithm to artificially generate a reference position for the location in which the user equipment is placed;
• c) the feeding the user equipment with position information by emulating a global satellite navigation system is repeated to emulate different conditions for one or both of the following:
• i) rapid movements of the user equipment;
• or
• ii) scenarios for acquisition of signals for the global satellite navigation system that are considered to be challenging;
• d) for initial transmissions by the user equipment, variation of the position of the user equipment is set to zero, to establish the reference transmission timing by the user equipment before common delay variations are introduced.

An apparatus comprising

• at least one processor;
• and
• at least one memory including computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus to perform at least:
• setting one or more common delays for a base station, the base station and a user equipment able to communicate via signals and to use the one or more common delays in communication, wherein the one or more common delays correspond to delay in communication of the signals in a path from a simulated satellite to a reference point, where the reference point is a point selected between the base station and the simulated satellite and where the user equipment is placed in a known location;
• setting ephemeris values for the base station for the simulated satellite and causing the ephemeris values to be broadcasted toward the user equipment, wherein the ephemeris values represent positioning of the simulated satellite through which the signals are supposed to travel;
• and
• in response to communication over the path by the user equipment, determining error corresponding to at least timing at least between the user equipment and the reference point.
