Abstract
A method for testing an air interface device by simulating multi-UE uplink virtual MIMO includes receiving, by a multi-UE simulator, a downlink signal transmission from an air interface device under test. The method further includes decoding, by the multi-UE simulator, the downlink signal transmission to identify simulated UEs with uplink resource block grants. The method further includes assigning, by the multi-UE simulator, uplink data transmissions for the simulated UEs with uplink resource block grants to antennas or cables such that uplink data transmissions for simulated UEs with overlapping uplink resource block grants are assigned to different antennas or cables. The method further includes testing, by the multi-UE simulator, uplink virtual MIMO processing capability of the air interface device under test by generating and transmitting uplink signals from the simulated UEs with the overlapping uplink resource block grants to the air interface device under test using the different antennas or cables.
