Testing methods and systems for mobile communication devices

A testing method for testing a mobile communication device, the method comprising:

• measuring a first three-dimensional antenna pattern of an active phased antenna array (AAS) of the mobile communication device by measuring at least two antenna sub-patterns associated with at least two different beamforming alignments of the AAS of the mobile communication device, with the AAS being maintained at the at least two different beamforming alignments during the measurement of the at least two antenna sub-patterns;
• combining the at least two antenna sub-patterns to obtain the first three-dimensional antenna pattern;
• calibrating a predefined base fading profile with the measured first three-dimensional antenna pattern to obtain an first optimized fading profile adapted to the first beamforming alignment;
• emulating a first channel model for emulation of a base station on the basis of the first optimized fading profile;
• performing a receiver test on the mobile communication device using the emulated first channel model;
• measuring a second three-dimensional antenna pattern of the AAS of the mobile communication device, with the AAS being maintained at a second beamforming alignment during the measurement, the second beamforming alignment being different from the first beamforming alignment;
• calibrating the first optimized fading profile with the measured second three-dimensional antenna pattern to obtain an second optimized fading profile adapted to the second beamforming alignment;
• emulating a second channel model for emulation of a base station on the basis of the second optimized fading profile;
• and
• performing a receiver test on the mobile communication device using the emulated second channel model.
