In one of the exemplary embodiments, the method would include not limited to receiving, via a first wireless receiver tuned to a licensed spectrum, a control message which at least indicates a pattern of a reference signal to be received; receiving, via a second wireless receiver tuned to an unlicensed spectrum, a first message which comprises the reference signal in the unlicensed spectrum; performing a measurement of the reference signal; generating a feedback based on the measurement of the reference signal; and transmitting, via a wireless transmitter tuned to the licensed spectrum, a second message which comprises the feedback of the reference signal in the licensed spectrum."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of transmitting reference signal in unlicensed spectrum for LTE-LAA system and wireless device using the same","description":"The disclosure is directed to method of transmitting a reference signal used by a wireless device in an unlicensed spectrum for a LTE-LAA communication system, and a wireless communication device usin","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9680617","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.
