Abstract:
A method includes receiving, by a base station, a sounding reference signal (SRS) symbol from a user equipment (UE). The method also includes estimating, by the base station, an uplink (UL) channel from the UE to a full dimensional multiple-input multiple-output (FD-MIMO) base station base band based on the received SRS symbol. The method also includes receiving, by the base station from the UE, an estimate of a downlink (DL) channel from the FD-MIMO base station base band to the UE. The method also includes performing, by the base station, a joint calibration by applying one or more calibration algorithms using channel state information (CSI) of the UL channel and the DL channel.
