The present invention is designed to reduce the impact which the variation of the amount of overhead within a subframe has upon the throughput of data channels. A user terminal, according to the present invention, has a transmitting/receiving section that receives a downlink (DL) signal and/or transmits an uplink (UL) signal in a subframe, and a control section that controls transport block sizes (TBSs) of the DL signal and/or the UL signal. The user terminal controls the TBSs based on overhead in the subframe or a desired coding rate.
