The sub-frame includes the beam restricted sub-frame and a normal sub-frame, setting information includes information indicating a sub-frame set as the beam restricted sub-frame among multiple sub-frames, the beam restricted sub-frame is a sub-frame transmitted only based on a first beam subset, the normal sub-frame is a sub-frame transmitted based on the first beam subset and a second beam subset, the first beam subset is the set of beams generated based on a first precoding matrix set, and the second beam subset is the set of beams generated based on a second precoding matrix set including the first precoding matrix set."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmitting downlink data on basis of beam restricted sub-frame","description":"The method comprises: a step in which the base station transmits to a terminal configuration information related to the beam restricted sub-frame; and a step in which the base station transmits downli","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9660712","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.
