With sticky region allocation, the sticky region may be negotiated during the establishment of a connection between a base station and a user terminal, and a single MAP information element (MAP IE) may inform the user terminal of the location of the sticky region. Then, a user terminal can receive/send data bursts for a certain connection in multiple OFDM/OFDMA frames without needing a MAP IE for locating each burst in subsequent frames. Accordingly, the size of the control overhead, such as the downlink (DL) and uplink (UL) MAP messages, may be reduced. The reduced control overhead may increase the frame resources available for data traffic and thus, may boost the overall efficiency and performance of OFDM/OFDMA wireless systems."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and systems for dynamic sticky region allocation in map-based communication systems","description":"Methods and apparatus for allocating, modifying, and terminating a fixed data region (termed “sticky region allocation”) in an orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8526390","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.
