The signal that is transmitted may be a probing signal having at least a predetermined temporally varying transmission pattern, and where determining includes correlating at least the predetermined temporally varying transmission pattern with changes, if any, in the monitored channel signal quality-related feedback. The channel signal quality-related feedback that is monitored may include at least one of ACK/NACK feedback, power control feedback, rate control feedback and channel quality indicator feedback."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Determination of coupling between radio devices","description":"A method includes transmitting, from a radio device of a secondary communication system, a signal into a channel of a primary communication system; monitoring channel signal quality-related feedback o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8483629","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.
