A channel estimation unit uses a pilot signal to obtain SINR for each RB. A feedback information generation unit converts SINR of each RB into a corresponding CQI. Moreover, as the transmission band width increases, the number X of the quantization bits is decreased when quantizing the average CQI, thereby generating feedback information. A radio transmission unit transmits feedback information from an antenna."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio reception device, radio transmission device, and feedback method","description":"Provided are a radio reception device, a radio transmission device, and a feedback method which can uniformly guarantee the feedback accuracy of an average channel quality indicator (CQI) even when th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8520760","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.
