The mobile communication system comprises a user terminal that feeds back feedback information of a target frequency band, to a base station. The feedback information includes combinations of precoder matrix information indicating the precoder matrix and rank information indicating the rank."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mobile communication system and communication control method","description":"A mobile communication system performs downlink multi-antenna transmission by applying a precoder matrix that defines transmission directionality of downlink and a rank that defines number of signal s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9735848","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.
