The full discovery physical layer capability corresponds to an alternative where a discovery-capable user terminal has a capability to perform both Discovery_Scan (on an uplink band) and Discovery_Tx (on a downlink band) operations. A Discovery_Tx operation corresponds to transmission of a discovery signal to another user terminal directly over the air. A Discovery_Scan operation corresponds to reception of the discovery signal from another user terminal directly over the air. The partial discovery physical layer capability corresponds to an alternative where the discovery-capable terminal has a capability to perform either Discovery_Scan operation (on the downlink band) or Discovery_Tx (on the uplink band) operation (or both)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Proximity service in communications","description":"Two physical layer user terminal capability alternatives are introduced for device-to-device discovery for FDD mode terminals: a full discovery physical layer capability, and a partial discovery physi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9826382","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.
