Additionally, when the first CSI-RS is an un-precoded CSI-RS, the first CSI feedback only includes a part of information of CSI feedback based on the un-precoded CSI-RS that is a precoding matrix indicator (PMI) or are the PMI and a rank indicator (RI). In another aspect, a CSI feedback method for a terminal is also disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reference signal transmission method, channel state information feedback method, base station and mobile station","description":"A terminal is disclosed that includes a processor that performs channel measurement based on a first Channel State Information-Reference Signal (CSI-RS) and performs channel measurement based on a sec","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11245450","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.
