Abstract

See full text

The present invention is designed so that uplink control signals can be transmitted adequately even when the number of component carriers that can be configured in a user terminal is expanded. A user terminal can communicate by using six or more component carriers, and has a receive receiving section that receives a DL signal, a transmission section that transmits a UL control signal, which includes a delivery acknowledgement signal in response to the DL signal, and a control section that controls a format to apply to the UL control signal, and the control section applies a format, having large capacity in comparison to a PUCCH format of an existing system in which the number of component carriers to be configured is five or less, to the UL control signal.
