NODE AND METHOD FOR ESTABLISHING BEAMFORMING FOR DOWNLINK COMMUNICATIONS

摘要

Example embodiments presented herein are directed towards an eNodeB (401), and method therein, for establishing beamforming for downlink communications in a multiple antenna system. The eNodeB may be configured to receive, from a user equipment, a plurality of signal quality assessments which correspond to a distinct direction within at least one correlated domain (e.g., an elevation and/or azimuth domain). Based on the signal quality assessments, at least one first and second signal quality assessment may be identified according to a predetermined signal characteristic. Thereafter, a transmission direction may be determined based on the at least one first and second signal quality assessment and associated directions within the at least one correlated domain. Based on the determined transmission direction, downlink communications may be transmitted to the user equipment.
