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 an uplink control channel of a subframe, wherein PUCCH formats are classified according to a modulation scheme and the number of bits transmitted in the subframe; encoding at least one type of UCI using block code comprising 11 basis sequences, wherein if the at least one type of UCI is equal or less than 11 bits, the block code is once used for the encoding, and if the at least one type of UCI is more than 11 bits, the block code is dually used for the encoding; and transmitting the at least one type of UCI at the determined transmission power in the uplink control channel, wherein in a case that the PUCCH format is PUCCH format 3 which uses quadrature phase shift keying as the modulation scheme, and the at least one type of UCI includes an acknowledgement/not-acknowledgement, ACK/NACK, and periodic channels state information, CSI, 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, 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 or 0. determining, based on a PUCCH format dependent value, transmission power to be applied to an uplink control channel of a subframe, wherein PUCCH formats are classified according to a modulation scheme and the number of bits transmitted in the subframe; encoding at least one type of UCI using block code comprising 11 basis sequences, wherein if the at least one type of UCI is equal or less than 11 bits, the block code is once used for the encoding, and if the at least one type of UCI is more than 11 bits, the block code is dually used for the encoding; and transmitting the at least one type of UCI at the determined transmission power in the uplink control channel, wherein in a case that the PUCCH format is PUCCH format 3 which uses quadrature phase shift keying as the modulation scheme, and the at least one type of UCI includes an acknowledgement/not-acknowledgement, ACK/NACK, and periodic channels state information, CSI, 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, 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 or 0. 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 or 0.
