Patent ID: 8755343

Claim:
A method for transmitting a physical uplink control channel (PUCCH) signal by a communication apparatus in a wireless communication system, comprising: setting transmit power for the PUCCH signal, wherein, if the PUCCH signal is transmitted on a subframe configured for a scheduling request (SR), the PUCCH signal includes one or more hybrid automatic repeat request acknowledgement (HARQ-ACK) bits and an SR bit, and wherein the transmit power for the PUCCH is determined by using the following equation: h ⁡ ( · ) = n HARQ + n SR - 1 N where, n HARQ is associated with the number of information bits of HARQ-ACK, N denotes a positive integer, and n SR is 1 when a transport block for an uplink shared channel (UL-SCH) is not present at the subframe and is 0 when the transport block for the UL-SCH is present at the subframe.
