  • Methods and systems for hybrid beamforming for MIMO communications
    Patent number: 10951286
    Abstract: Methods and apparatuses for hybrid beamforming are described. The described methods and apparatuses related to hybrid beamforming for single user multiple-input multiple-output (SU MIMO) communications and for multi-user multiple-input single-output (MU MISO) communications. The radio frequency (RF) precoder and baseband precoder are determined such that the hybrid precoder has a minimum or near minimum chordal distance from an optimal precoder. Feedback information enables the transmitter to select columns from a set of discrete Fourier transform (DFT) columns to form the RF precoder matrix.
