The present invention provides a method by which a mobile station (MS) operates a beam in a communication system supporting a hybrid multiple-input multiple-output (MIMO) mode, the method comprising the steps of: receiving, from a base station (BS), information related to the number of beams to be used, by the BS, for a beam training process; receiving, from the BS, a downlink reference signal (RS); performing a channel estimation process on the basis of the downlink RS; and transmitting, to the BS, information related to the number of beams to be used by the MS, after performing the channel estimation process."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Beam operation device and method in communication system supporting hybrid multiple-input multiple-output mode","description":"The present invention relates to a 5th-generation (5G) or pre-5G communication system to be provided for supporting a data transmission rate higher than that of a 4th-generation (4G) communication sys","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10516448","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.
