Abstract: The present invention is designed so that the transmission of A/Ns can be controlled properly when the reference value for the timing for transmitting signals is controlled in radio base stations and/or user terminals. A user terminal, according to the present invention, has a receiving section that receives a downlink (DL) shared channel, and a control section that controls transmission of retransmission control information in response to the DL shared channel. The control section controls the transmission of the retransmission control information based on a reference value that is configured for timing for transmitting the retransmission control information.
