Abstract:
This invention presents a RF channel emulator for testing a large-scale Multiple-User Multiple-Input Multiple-Output (MU-MIMO) wireless communication system, including embodiments of using over-the-air channels for connecting a RF channel emulator and a large-scale MU-MIMO wireless communication system, calibration processes that maintain the over-the-air channel reciprocity, and emulation of carrier aggregation.

Claim (Index 1):
A method for testing a Multiple-User Multiple-Input Multiple-Output (MU-MIMO) wireless communication system comprising connecting the signals from and to K testing User Equipment (UEs) each of which has one or more transmitting and receiving paths and the associated antennas with a MU-MIMO Channel Emulator (M-CE) using wired or over-the-air (OTA) wireless connections, wherein K>1; connecting the signals from and to a Base Station (BS) with M transmitting and receiving paths and the associated antennas with a M-CE using wired or wireless connections, wherein the BS is capable of spatial multiplexing N beams on the same frequency and time resource to communicate with the K UEs wherein M\u2265N\u2265K and the BS communicates with a UE using one or more spatial beams; in the M-CE in the downlink, obtaining the baseband digital signals from the signals received from the M transmitting paths or the associated antennas of the BS, applying to the baseband digital signals filters designed based on one or more models of the channels from the BS to the K UEs in the intended environment or application to map the set of signals transmitted by the M transmitting paths or the associated antennas of the BS to the set of signals to be received by the receiving paths or the associated antennas of the K UEs, and converting and transmitting the filtered digital baseband signals to the receiving paths or associated antennas of the K UEs; and, in the M-CE in the uplink, applying to the baseband signals filters designed based on one or more models of the channels from the K UEs to the BS in the intended environment or application to map the set of signals transmitted by the transmitting paths or the associated antennas of the K UEs to the set of signals to be received by the M receiving paths or the associated antennas of the BS, and converting and transmitting the filtered digital baseband signals to the receiving paths or associated antennas of the BS.
