Claim Text:
1. A beamforming processor to configure a large aperture array antenna of a base station for communication at millimeter-wave (mmW) frequencies, within a 60 GHz frequency band, with a plurality of user equipment (UE), the beamforming processor configured to: allocate each UE a non-interfering spectral portion of a full channel bandwidth, the full channel bandwidth being 2 GHz wide; determine a transmit power allocation for each UE for use within the allocated portion of bandwidth to increase power spectral density (PSD) for each UE within the allocated portion of bandwidth, the transmit power allocation based on a total transmit power (Pmax) limitation, a signal power density (Smax) limitation and a PSD limitation; perform multi-beam beamforming to concurrently direct a plurality of multi-user multiple-input multiple-output (MU-MIMO) antenna beams to the UEs for a concurrent transmission of data streams to the UEs within their allocated non-interfering spectral portion in accordance with the transmit power allocation; instruct the UEs to refrain from utilizing the full channel bandwidth when allocated a non-interfering spectral portion; and communicate with the UEs within the allocated non-interfering spectral portion instead of the full channel bandwidth.
