Abstract

The present invention is designed to communicate using a radio interface with improved scalability in the frequency domain. According to the present invention, a user terminal includes a receiving section that receives a downlink control signal including information about the assignment of a downlink data 5 signal and receives the downlink data signal based on the downlink control signal, and a transmission section that transmits an uplink control signal including transmission acknowledgment information in response to the downlink data signal. Further, a plurality of frequency domain units constituting the entire frequency band as a block are formed. The downlink control signal, the downlink data 10 signal and the uplink control signal are time-division-multiplexed in the same frequency domain unit. FIG. 3
