A user terminal communicates, in time division duplexing, with a radio base station that reconfigures the DL/UL configuration, and has a judging section that judges a delivery acknowledgement in response to each DL subframe, and a feedback control section that allocates a delivery acknowledgement signal in response to each DL subframe to a UL subframe and sends feedback, and, when the number of DL subframes that correspond to a UL subframe is greater than a predetermined value in a radio frame after the reconfiguration of the DL/UL configuration, the feedback control section bundles at least part of the delivery acknowledgement signals for a plurality of DL subframes corresponding to the UL subframe, and sends feedback."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"User terminal, radio base station and radio communication method","description":"The present invention is designed to feed back feedback signals such as delivery acknowledgement signals properly even when the DL/UL configuration is reconfigured in TDD.
