By reconfiguring the radio frame structure, the invention can flexibly support different coverage ranges, enhance the flexibility of satisfying different service requirements, and implement the coexistence of two types of TDD systems."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and an apparatus for determining the radio frame structure of time division duplex system","description":"A method for determining the radio frame structure of a Time Division Duplex system is disclosed, which comprises: configuring, by the network side, the radio frame structure used for service transmis","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8472465","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.
