The method for transmitting CSI by a terminal in a wireless access system that supports massive multi-input multi-output (MIMO), according to one embodiment of the present invention, may comprise the steps of: receiving a signal including report period information; receiving downlink data including a reference signal; measuring first CSI using the reference signal; acquiring second CSI using the first CSI; and reporting the first CSI or the second CSI to a base station based on the report period information. According to the present invention, the first CSI may be information on a first antenna set including antennas for transmitting the reference signal, and the second CSI may be information on a second antenna set including antennas not transmitting the reference signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for transceiving channel state information in wireless access system, and apparatus for supporting same","description":"The present invention relates to a wireless access system that supports massive MIMO, and provides a method for transceiving channel state information (CSI) for operating the massive MIMO and an appar","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9800379","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.
