Beamforming for multiple-input multiple-output (MIMO) modes in open radio access network (O-RAN) systems

One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause a non-real time (non-RT) radio access network (RAN) intelligent controller (RIC) to:

• request, from an open distributed unit (O-DU), beamforming configuration information associated with a plurality of multiple-input/multiple-output (MIMO) modes, the beamforming configuration information comprising at least one beamforming parameter for each of the plurality of MIMO modes, the at least one beamforming parameter selected from beam direction, horizontal beam width, vertical beam width, and beam power gain;
• receive, from the O-DU, the beamforming configuration information;
• request, from the O-DU based on the beamforming configuration information, measurements associated with the plurality of MIMO modes, the measurements comprising performance metrics associated with spatial distribution of user equipment for each of the plurality of MIMO modes;
• receive, from the O-DU, the measurements associated with the plurality of MIMO modes;
• and
• based on the received measurements, train an artificial intelligence/machine learning (AI/ML) model that is to predict relative beamforming performance between the plurality of MIMO modes by determining differences in beamforming characteristics between a first MIMO mode of the plurality of MIMO modes and a second MIMO mode of the plurality of MIMO modes.
