Abstract
Systems and methods of beam selection for hybrid beamforming are disclosed. Determining a select set of beam indices for use with transmissions to a receiver using hybrid precoding includes obtaining metrics for a first set of pairs of beam indices for use with the transmissions, where each pair includes a transmit beam index for a transmit antenna and a receive beam index for a receiver antenna. The method also includes selecting a first subset of the first set of pairs according to a first pruning decision, where the first subset includes at least one of the pairs. The method also includes processing only the first subset to determine the selected set of beam indices for use with the transmissions using hybrid precoding. In this way, a beam selection is made without the need to perform an exhaustive search of beams which is typically a time consuming process.
