In one embodiment, an alternative duplex mode of operation is disclosed (semi-static half duplex FDD operation) that enables coordination between the client device (e.g., UMTS UE) and the base station in order to centralize control of radio resource control (RRC) to the base station. The disclosed methods and apparatus may also advantageously incorporate hybrid ARQ (HARQ) or comparable timing requirements into their operation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Adaptive operational full-duplex and half-duplex FDD modes in wireless networks","description":"Methods and apparatus that enable a wireless network system to dynamically change between full-duplex FDD operation and half-duplex FDD operation in order to take advantage of operational aspects of b","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8542617","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.
