Systems and methods for digital and analog beamforming in wireless communications

A wireless communication device, comprising:

• a first module configured to form beams in the digital domain by generating digitally pre-coded spatial streams;
• a plurality of second modules configured to form beams in the analog domain by measuring signal and channel quality metrics from received signals and calculating gain and phase adjustment values, the second modules adjusting the gain and phase of the digitally pre-coded spatial streams;
• and
• a plurality of antenna arrays configured to transmit the digitally pre-coded spatial streams,
• wherein a radio base station receives and applies digital beamforming to the spatial streams, wherein the radio base station does not apply analog beamforming.

A method, comprising:

• receiving signals by a plurality of antenna arrays in a wireless communication device, wherein the signals are transmitted by a radio base station using digital beamforming, wherein the radio base station does not apply analog beamforming;
• measuring, by the wireless communication device, signal and channel quality metrics from the received signals and calculating gain and phase adjustment values;
• forming beams in the analog domain, by the wireless communication device, by adjusting the gain and phase of the received signals;
• and
• forming beams in the digital domain, by the wireless communication device, by generating digital weights and applying the digital weights to the gain and phase adjusted received signals.
