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 21):
An apparatus for emulating a Multiple-User Multiple-Input Multiple-Output (MU-MIMO) wireless communication system comprising wired or over-the-air (OTA) wireless interface for connecting the apparatus with K testing User Equipment (UEs) wherein K>1 and each UE has one or more transmitting and receiving paths and the associated antennas; wired or over-the-air (OTA) wireless interface for connecting the apparatus with a Base Station (BS) which has M transmitting and receiving paths and the associated antennas, 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; one or more memories for storing instructions and channel models; one or more processors which transforms signals transmitted by a BS (and/or by K UEs) to signals received by K UEs (and/or by a BS) to emulate the communication channels between the BS and the K UEs; a module that obtains the baseband digital signals from the signals received from the M transmitting paths or the associated antennas of the BS, and sends the baseband signals to the one or more processors which apply 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; a module that converts and transmits the filtered digital baseband signals to the receiving paths or associated antennas of the K UEs; a module that obtains the baseband digital signals from the signals received from the transmitting paths or the associated antennas of the K UEs, and sends the baseband signals to the one or more processors which apply to the baseband digital 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 a module that converts and transmits the filtered digital baseband signals to the M receiving paths or associated antennas of the BS.
