  • Patent number: 11736164
    Abstract: A beamforming vector for a communication link between a first device and a second device may be determined by searching, based on a signal from the second device, a hierarchical beamforming codebook including a plurality of beamforming vectors occupying a plurality of levels. The plurality of beamforming vectors may include a first beamforming vector and a second beamforming vector occupying a first level of the hierarchical beamforming codebook. The first beamforming vector may have a first angular range while the second beamforming vector may have a second angular range. The first beamforming vector may be selected as the beamforming vector based on a respective posterior probability an angle-of-arrival of the signal from the second device being in each of the first angular range and the second angular range. Related systems and articles of manufacture, including computer program products, are also provided.
