System and method for modeling wireless communication environment for new radio-unlicensed signals

A non-transitory computer readable medium storing instructions for modeling a wireless communication environment between user equipment (UE) and an access point (AP) within a test space, that when executed by at least one processing unit, the instructions cause the at least one processing unit to:

• obtain data transmissions received at the UE from the AP, wherein at least a portion of the data transmissions is associated with new radio-unlicensed (NR-U) signals;
• import and filter an NR-U UE log to provide filtered NR-U data, wherein the NR-U UE log has been previously populated by a field capture tool;
• generate a power profile for the wireless communication environment using sampled power level measurements from the filtered NR-U data in the NR-U UE log;
• create a digital twin map of the test space based on practical geometric configurations of the test space, wherein the digital twin map shows relative positions of the AP and a plurality of waypoints corresponding to a plurality of positions of the UE moving in a route through the test space;
• generate a Doppler profile for the UE using the digital twin map, wherein the Doppler profile is dependent on direction of movement of the UE relative to the AP when moving in the route through the test space;
• generate a power delay profile (PDP) profile for the UE using the digital twin map;
• and
• build an emulation model for the UE based on the power profile, the Doppler profile and the PDP profile.

A system for modeling a wireless communication environment between user equipment (UE) and an access point (AP) within a test space, the system comprising:
