Provided are a method for a terminal transmitting uplink control information (UCI) through a physical uplink control channel (PUCCH) in a wireless communication system, and a terminal using the method. A transmission power to be applied to the uplink control channel is determined on the basis of a value subordinate to a PUCCH format, and at least one type of UCI is transmitted from the physical uplink control channel by using the transmission power that is determined, wherein when the PUCCH format is PUCCH format 3, and the at least one type of UCI includes acknowledgement/negative-acknowledgement (ACK/NACK) and periodic channel state information (CSI), the value subordinate to the PUCCH format is determined on the basis of the number of bits of the ACK/NACK and the number of bits of the periodic CSI. |

1. A method for receiving uplink control information (UCI) through a physical uplink control channel (PUCCH) in a wireless communication system, the method performed by a base station and comprising:
transmitting data to a user equipment; and receiving at least one type of UCI, transmitted from the user equipment, through a PUCCH of a subframe, wherein transmission power of the PUCCH is determined based on a PUCCH format dependent value, PUCCH formats being classified according to a modulation scheme and the number of bits transmitted in the subframe, wherein if the PUCCH format is PUCCH format 3 which uses quadrature phase shift keying (QPSK) 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) for the data 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,
h(nCQI,nHARQ,nSR)=(nHARQ+nSR+nCQI−1)/3 [Equation 1]h(nCQI,nHARQ,nSR)=(nHARQ+nSR+nCQI−1)/2, [Equation 2] in Equations 1 and 2 given above, h(nCQI, nHARQ,nSR) represents the PUCCH format dependent value, nHARQ represents the number of bits of the ACK/NACK, nCQI represents the number of bits of the periodic CSI, and nSR is 1 or 0 according to a configuration for a scheduling request (SR) for the user equipment. |
