Abstract: A method and apparatus for transmitting control information are discussed. The method can include generating uplink control information (UCI) and transmitting the UCI through an physical uplink control channel (PUCCH) in a subframe, wherein when the subframe is configured for transmission of a scheduling request (SR) and when transmission of a hybrid automatic repeat request (HARD)-acknowledgement (ACK) coincides with the subframe, transmission power of the PUCCH is determined based on a number of HARQ-ACK information bits and a SR bit. A value of the SR bit can be determined by whether or not the subframe is configured for a scheduling request.
