Method and apparatus for transmitting uplink control information in wireless communication system
First Claim
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 (BS) and comprising:
- transmitting data to a user equipment (UE); and
receiving acknowledgement/negative-acknowledgement (ACK/NACK) information for the data, from the UE, through the PUCCH,wherein transmission power for the PUCCH is determined based on a PUCCH format dependent value, andwherein;
when the ACK/NACK information and periodic channels state information (CSI) are received through a PUCCH format 3,if a total sum of the ACK/NACK information and the periodic CSI is larger than 11 bits, the PUCCH format dependent value is determined as Equation 1 given below, andif a total sum of the ACK/NACK information and the periodic CSI 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 a number of bits of the ACK/NACK information,nCQI represents a number of bits of the periodic CSI, andnSR is 1 or 0.

Abstract
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.
