A terminal apparatus for performing wireless communication with a base station apparatus includes: a receiving unit that receives a radio signal transmitted from the base station apparatus; a CCA-variable channel information processing unit that acquires first CCA-variable channel instruction information contained in the radio signal and containing information regarding a range of a CCA level that is available on a certain channel and that is used for clear channel assessment; and a higher layer unit that selects, according to the first CCA-variable channel instruction information, a channel to be used."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Terminal apparatus and base station apparatus","description":"An object of the present invention is to protect the communication of a legacy terminal while achieving favorable communication rendering the CCA level of a CCA-variable terminal apparatus variable in","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10477456","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.
