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 an acknowledgement/not-acknowledgement ACK/NACK and periodic channels state information CSI, and the PUCCH format dependent value is determined based on a number of bits of the ACK/NACK and a number of bits of the periodic CSI, and wherein: if PUCCH format 3 is configured to be transmitted through two antenna ports or if a total sum of the at least one type of UCI is larger than 11 bits, the PUCCH format dependent value is determined as Equation 1 given below, and if the at least one type of UCI is transmitted through the single antenna port and a total sum of the at least one type of UCI is equal to or smaller than 11 bits, the PUCCH format dependent value is determined as Equation 2, h n CQI n HARQ n SR = n HARQ + n SR + n CQI − 1 / 3 h n CQI n HARQ n SR = n HARQ + n SR + n CQI − 1 / 2 where, in Equations 1 and 2 given above, h(n CQI, n HARQ,n SR) represents the PUCCH format dependent value, n HARQ represents the number of bits of the ACK/NACK, n CQI represents the number of bits of the periodic CSI, and n SR is 1 in the case where the subframe is set for a scheduling request 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 an acknowledgement/not-acknowledgement ACK/NACK and periodic channels state information CSI, and the PUCCH format dependent value is determined based on a number of bits of the ACK/NACK and a number of bits of the periodic CSI, and wherein: if PUCCH format 3 is configured to be transmitted through two antenna ports or if a total sum of the at least one type of UCI is larger than 11 bits, the PUCCH format dependent value is determined as Equation 1 given below, and if the at least one type of UCI is transmitted through the single antenna port and a total sum of the at least one type of UCI is equal to or smaller than 11 bits, the PUCCH format dependent value is determined as Equation 2, h n CQI n HARQ n SR = n HARQ + n SR + n CQI − 1 / 3 h n CQI n HARQ n SR = n HARQ + n SR + n CQI − 1 / 2 where, in Equations 1 and 2 given above, h(n CQI, n HARQ,n SR) represents the PUCCH format dependent value, n HARQ represents the number of bits of the ACK/NACK, n CQI represents the number of bits of the periodic CSI, and n SR is 1 in the case where the subframe is set for a scheduling request and 0 in other cases. if PUCCH format 3 is configured to be transmitted through two antenna ports or if a total sum of the at least one type of UCI is larger than 11 bits, the PUCCH format dependent value is determined as Equation 1 given below, and if the at least one type of UCI is transmitted through the single antenna port and a total sum of the at least one type of UCI is equal to or smaller than 11 bits, the PUCCH format dependent value is determined as Equation 2, h n CQI n HARQ n SR = n HARQ + n SR + n CQI − 1 / 3 h n CQI n HARQ n SR = n HARQ + n SR + n CQI − 1 / 2 where, in Equations 1 and 2 given above, h(n CQI, n HARQ,n SR) represents the PUCCH format dependent value, n HARQ represents the number of bits of the ACK/NACK, n CQI represents the number of bits of the periodic CSI, and n SR is 1 in the case where the subframe is set for a scheduling request and 0 in other cases.
