  • Adaptive digital precoder codebook configurations for mmWave communication based on hybrid beamforming
    Patent number: 11152980
    Abstract: Base stations and user terminals may adaptively configure a digital precoder codebook for mmWave-based hybrid beamforming, such as by determining at least one analog beamformer and combiner, determining at the user terminal a lowest codebook resolution of digital precoding that can be used to achieve at least one performance parameter, and communicating to the base station the determined lowest codebook resolution of digital precoding. The adjustment of digital precoder codebook resolution, on top of analog beamforming, across different radio resources (e.g. time/frequency) may optimize feedback efficiency for a user terminal. In some cases, the user terminal may also receive from a base station an assistance parameter relating to an achievable performance gain using digital precoding. The user terminal may use the received assistance parameter in determining the digital precoder codebook resolution.
