A radio base station transmits downlink reference signals that are specific to a plurality of transmission beams, a plurality of user terminals feed back coarse channel state information that is acquired by channel estimation, to the radio base station, the radio base station selects a plurality of user terminals to make feed back accurate channel state information based on the coarse channel state information, a plurality of user terminals that are selected feed back accurate channel state information, the radio base station determines a plurality of user terminals to non-orthogonal-multiplex, per transmission beam, based on the accurate channel state information, and non-orthogonal-multiplexes downlink signals, and a plurality of user terminals that are determined, after having canceled interference between the transmission beams by means of a linear filter, cancels downlink signals for other terminals, from the downlink signals that are non-orthogonal-multiplexed in each transmission beam."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio base station, user terminal, radio communication method and radio communication system","description":"The present invention is designed to provide a radio base station, a user terminal, a radio communication method and a radio communication system of novel structures that can achieve improved throughp","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10536203","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.
