The present invention is designed so that retransmission control is executed appropriately in smaller units than TBs (for example, in units of CBs, in units CBGs, etc.). A user terminal according to one aspect of the present invention has a receiving section that receives a downlink (DL) signal including one or more code blocks (CBs), and a control section that controls transmission of delivery acknowledgment information for the DL signal per CB or per code block group (CBG) including or one or more CBs, and a CB or a CBG where a negative acknowledgment (NACK) is indicated by the delivery acknowledgment information is retransmitted by using a numerology that is the same as or different from that of initial transmission.
