Claim Text:
1. 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; and transmitting at least one type of UCI at the determined transmission power in the uplink control channel, wherein, if the PUCCH format is PUCCH format 3 which uses quadrature phase shift keying as the modulation scheme and in which 48 bits can be transmitted, and if the at least one type of UCI includes an acknowledgement/not-acknowledgement (ACK/NACK) and periodic channels state information (CSI), the PUCCH format dependent value is determined based on the number of bits of the ACK/NACK and the 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 given below, in Equations 1 and 2 given above, h(n n n n
