Abstract
Transmission methods and systems include calibrating a mismatch between uplink and downlink digital elements of hybrid beamforming transceivers. calibrating a mismatch between uplink and downlink analog elements of the plurality of hybrid beamforming transceivers. Respective downlink channels are estimated between a user equipment and the hybrid beamforming transceivers using respective mismatch calibrations for the digital and analog elements of each of the hybrid beamforming transceivers. Data is transmitted to the user equipment from the hybrid beamforming transceivers using a distributed beamforming pattern based on the estimated downlink channels.
