摘要
A hybrid digital and analog beamforming device for a node operable with an antenna array is disclosed. In an example, the hybrid digital and analog beamforming device can include computer circuitry configured to: Segment antenna elements of an antenna array into at least two groups of antenna elements; map antenna ports for transmission chains to one group of the antenna elements; constrain digital precoding weights for a digital precoder for the antenna elements, where the digital precoding weight includes a digital phase and amplitude; and determine analog precoding weights for an analog precoder for the antenna elements, where the analog precoding weight includes an analog phase.
