Zusammenfassung:	According to an example, a massive multiple-input multiple-output (mMIMO) system operable for beamforming actuation may comprise an open radio access network radio unit (O-RU) having a processing device operable to: compute one or more of a predictive channel estimate, a beamforming estimate, or an antenna calibration; compute, based on an objective function having one or more of the predictive channel estimate, the beamforming estimate, or the antenna calibration as inputs, a power level for a data stream associated with a transmitting antenna path, wherein the power level for the data stream is selected to facilitate an equal-power distribution across a plurality of transmitting antenna paths; and set the power level for the data stream associated with the transmitting antenna path.
