In the case where a block error occurs continuously for a predetermined number of times or longer and an amount of decrease in the reception quality is lower than a predetermined value, the directivity control unit re-adjusts a directivity to decrease the block error, based on a result of the estimation of the block error and a result of the measurement of the reception quality, the re-adjusted directivity being one of the directivities of the antennas."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio communication device and method of controlling directivity","description":"A radio communication device includes: a directivity control unit that configures each of directivities of a plurality of antennas; a directivity switching unit that switches between the directivities","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9825719","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.
