Title:
BASE STATION, COMMUNICATION CONTROL METHOD, AND PROCESSOR
Document Type and Number:
WIPO Patent Application WO/2014/208350
Kind Code:
A1
Abstract:
This base station, which manages a cell in a mobile communication system that supports downlink multi-antenna transmission, receives beamforming control information provided as feedback from each of a plurality of beamforming-target terminals connected to the cell in question and null-steering control information provided as feedback from a null-steering-target terminal. If there are no beamforming-target terminals from which beamforming control information that matches the null-steering control information was provided as feedback, the base station selects, as a pair terminal, a beamforming-target terminal from which beamforming control information containing a predetermined rank indicator was provided as feedback.
