The radio communication method of the present invention includes a plurality of base station apparatuses that transmit CSI-RSs for measuring CSI and a user terminal that communicates with the plurality of base station apparatuses, and, when a plurality of CSI processes, which are combinations of SMRs and IMRs, are configured, in each of the base station apparatuses, a CSI process for requesting CSI with a nearest CSI reference resource in a subframe of the subframe number N-4 or an earlier subframe is configured, and in the user terminal, the CSI process configured in each of the base station apparatuses is determined, and, the CSI feedback process is performed based on the determination."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio communication system, base station apparatus, user terminal and radio communication method","description":"The present invention is designed to provide a radio communication system, a base station apparatus, a user terminal and a radio communication method, whereby, when a plurality of kinds of CSI process","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9801190","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.
