In one embodiment, a method of operation of a wireless device includes receiving a carrier signal transmitted by a radio access node and detecting, in the carrier signal, a first physical signal that primarily supports synchronization and cell identification and a second physical signal that supports a functionality other than synchronization and cell identification. A time-domain spacing between the first and second physical signals is a function of a characteristic of the carrier signal. The method further includes determining a characteristic of the carrier signal based on a time-domain spacing between the first and second physical signals detected in the carrier signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Synchronization sequences and carrier type detection","description":"Systems and methods relating to detecting one or more characteristics (e.g., a carrier type or a carrier mode) of a carrier signal transmitted by a radio access node of a cellular communications netwo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9755880","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.
