The disclosure relates to a beamforming device (200), including: a first beamforming circuit (201) configured to generate a first beam (211) based on a first set of beamforming coefficients; a second beamforming circuit (202) configured to generate a second beam (212) based on a second set of beamforming coefficients; and a scheduling circuit (203) configured to allocate (204, 206) a first set of frequency resources, a second set of frequency resources, the first set of beamforming coefficients and the second set of beamforming coefficients to a plurality of mobile stations (UE0, UE1, UE2) based on an optimality criterion related to a target scheduling metric.
