Abstract
Systems and methods of beam training for hybrid beamforming are disclosed. In some embodiments, a method of operation of a receiver includes identifying multiple sets of beam indices for use with transmissions from a transmitter using hybrid precoding. The method also includes communicating the sets of beam indices to the transmitter for use with transmissions using hybrid precoding and receiving a transmission from the transmitter using one of the sets of beam indices. In some embodiments, each set of beam indices is for a different transmission mode. In this way, a transmission mode may be changed without the need to perform re-training of beams which is typically a time consuming process.
