Abstract
According to one aspect of the present invention, a user terminal has a transmission section that performs UL grant-free transmission, in which UL data is transmitted without a UL transmission command from a radio base station, a receiving section that receives a DL signal that is transmitted from the radio base station in response to the UL grant-free transmission, and a control section that monitors the DL signal in a predetermined range, and controls retransmission of the UL data or transmission of new data, based on the DL signal received.
