A terminal for controlling the physical uplink control channel (PUCCH), according to the present invention, comprises: a processor for deciding the uplink transmission power for a PUCCH format 3 transmission; and a transmitter for transmitting the PUCCH format 3 at the uplink transmission power that is decided, wherein the processor distinguishes and decides the uplink transmission power from bits of the PUCCH format 3, based upon a predetermined number of information bits, the processor controls so that a different diversity method is applied to the PUCCH format 3, based upon the predetermined number of information bits, and wherein the transmitter transmits the PUCCH format 3 to which the different diversity method is applied with respect to the PUCCH format 3, by means of the processor, based upon the predetermined number of information bits.
