When there exists no beamforming target terminal that feeds back the beamforming control information that coincides with the null steering control information, the base station selects, as a pair terminal, a beamforming target terminal that feeds back the beamforming control information containing a predefined rank indicator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Base station, communication control method, and processor","description":"In a mobile communication system that supports downlink multi-antenna transmission, a base station managing a cell receives beamforming control information fed back from each of a plurality of beamfor","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9698886","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
