  • Detection of weak users in beam selection for massive MIMO receiver
    Patent number: 11082119
    Abstract: There is disclosed a method of operating a receiver arrangement in a radio access network. The receiver arrangement is adapted for receiving a plurality of antenna signals from a plurality of antennas, wherein the plurality of signals is collected to form a collected signal. The method includes transforming the collected signal into beam space based on a transform base, to provide a set of beams, selecting a subset of beams from the set of beams and evaluating the subset of beams for a quality requirement. If evaluating results in the quality requirement not being fulfilled, either the subset of selected beams is changed and it is returned to evaluating or the transform base is changed and it is returned to transforming. The disclosure also pertains to related methods and devices.
