Therefore, reducing calculation complexity on a terminal side of channel measurement and reducing a resource occupied for channel measurement and feedback in a multi-antenna port."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-antenna channel measurement method and apparatus","description":"A multi-antenna channel measurement method is provided, where: a base station sends a first channel state information-reference signal (CSI-RS) and a second CSI-RS to the terminal, and the first CSI-R","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10530450","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.
