The method includes obtaining partial channel state information from a reference signal transmitted by a number X, 1≤X<M, of said transmitting antenna ports and received by all of said receiving antenna ports, said partial channel state information providing a measure for the N×X propagation channels between all of said receiving antenna ports and said transmitting antenna ports. Also disclosed are corresponding devices and computer programs. Also disclosed is a method for controlling transmission based on estimated channel state information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and devices for estimation of MIMO channel state information","description":"A method for estimating Multiple Input Multiple Output, MIMO, channel state information for a radio link between a first radio node including a number N, N≥2, of receiving antenna ports and a second r","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11233553","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.
