This may reduce uplink feedback overheads and enable the transmitting end to quickly determine the preferred coordinated transmitting node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for feeding back information, and terminal","description":"A method for feeding back information includes: measuring a CQI of a link between each coordinated transmitting node in a coordinated transmitting node set and a terminal; using the CQI of and an RI v","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9590788","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.
