Abstract
The subject matter described herein includes methods, systems, and computer readable media for simulating per-UE Doppler shifts. One exemplary method includes generating uplink signals to be transmitted from a plurality of different simulated UEs to an air interface device under test. The method further includes applying per-UE Doppler shifts to the signals, wherein applying per-UE Doppler shifts includes applying different Doppler shifts to at least some of the signals. The method further includes transmitting the signals to the air interface device under test.
