A rank indicator (RI) and a precoding matrix indicator (PMI) can be carried on a dedicated control channel (DCCH) and be specified through a physical downlink control channel (PDCCH)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of transmitting channel information in multiple antenna system","description":"A method of transmitting channel information in a multiple antenna system includes receiving the channel information comprising rank information, and transmitting a confirm message through a downlink ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8488537","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.
