Advantageously, the abbreviated identifier is derived from a full identifier, e.g., a full-length device identifier taken from a full identifier space that is larger than the numeric range represented by the abbreviated identifier space. Use of the abbreviated identifier with its smaller numeric range results in more robust synchronization sequence detection at a receiver, and requires less complexity than would be required if sequence detection operated over the full identifier space."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for mapping identities to device-to-device synchronization sequences","description":"In one aspect of the teachings herein, Device-to-Device, D2D, synchronization signals are generated as a function of an abbreviated identifier associated with the D2D synchronization signals, e.g., th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9681472","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.
