METHOD AND DEVICE FOR CONDUCTING DOWNLINK CORRECTION IN MASSIVE MULTIPLE-INPUT MULTIPLE-OUTPUT SYSTEM

摘要

A method and device for conducting downlink correction in a massive multiple-input multiple-output system. The method comprises: grouping a plurality of downlink radio-frequency channels, so as to form a plurality of channel groups; conducting downlink correction processing on the plurality of channel groups, so as to obtain downlink correction weights of the plurality of downlink radio-frequency channels; and conducting compensation on downlink signals sent through the plurality of downlink radio-frequency channels using the downlink correction weights of the plurality of downlink radio-frequency channels.
