A method for transmitting, by user equipment, uplink control information,UCI, through a physical uplink control channel, PUCCH, in a wireless communication system, the method comprising: determining, based on a PUCCH format dependent value, transmission power to be applied to a PUCCH format 3, wherein PUCCH formats are classified according to a modulation scheme and a number of bits transmitted in a subframe; and transmitting at least one type of UCI at the determined transmission power in the PUCCH format 3, wherein the PUCCH format 3 uses quadrature phase shift keying as the modulation scheme and in which 48 bits can be transmitted, the at least one type of UCI includes only an acknowledgement/not-acknowledgement ACK/NACK or scheduling request, SR, without a periodic channel state information,CSI, and wherein: if a total sum of the at least one type of UCI is larger than 11 bits or the PUCCH format 3 is configured to be transmitted through two antenna ports, the PUCCH format dependent value is determined in Equation 1 given below and in other cases, the PUCCH format dependent value is determined in Equation 2, h = n HARQ + n SR − 1 / 3 h = n HARQ + n SR − 1 / 2 where, in Equations 1 and 2 given above, h represents the PUCCH format dependent value, n HARQ represents a number of bits of the ACK/NACK, and n SR is 1 in the case where the subframe is set for the SR and 0 in other cases. determining, based on a PUCCH format dependent value, transmission power to be applied to a PUCCH format 3, wherein PUCCH formats are classified according to a modulation scheme and a number of bits transmitted in a subframe; and transmitting at least one type of UCI at the determined transmission power in the PUCCH format 3, wherein the PUCCH format 3 uses quadrature phase shift keying as the modulation scheme and in which 48 bits can be transmitted, the at least one type of UCI includes only an acknowledgement/not-acknowledgement ACK/NACK or scheduling request, SR, without a periodic channel state information,CSI, and wherein: if a total sum of the at least one type of UCI is larger than 11 bits or the PUCCH format 3 is configured to be transmitted through two antenna ports, the PUCCH format dependent value is determined in Equation 1 given below and in other cases, the PUCCH format dependent value is determined in Equation 2, h = n HARQ + n SR − 1 / 3 h = n HARQ + n SR − 1 / 2 where, in Equations 1 and 2 given above, h represents the PUCCH format dependent value, n HARQ represents a number of bits of the ACK/NACK, and n SR is 1 in the case where the subframe is set for the SR and 0 in other cases. if a total sum of the at least one type of UCI is larger than 11 bits or the PUCCH format 3 is configured to be transmitted through two antenna ports, the PUCCH format dependent value is determined in Equation 1 given below and in other cases, the PUCCH format dependent value is determined in Equation 2, h = n HARQ + n SR − 1 / 3 h = n HARQ + n SR − 1 / 2 where, in Equations 1 and 2 given above, h represents the PUCCH format dependent value, n HARQ represents a number of bits of the ACK/NACK, and n SR is 1 in the case where the subframe is set for the SR and 0 in other cases.
