Abstract: A wireless communication system is disclosed. Disclosed herein are methods for transmitting a physical uplink control channel (PUCCH) signal in a wireless communication system, which includes setting transmit power for the PUCCH signal, and an apparatus thereof. 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. When determining the transmit power for the PUCCH, the SR bit is selectively considered depending on whether or not a transport block for an uplink shared channel (UL-SCH) is present in the subframe.

Abstract: A method for transmitting control information using PUCCH format 3 in a radio communication system includes detecting one or more Physical Downlink Control Channels (PDCCHs), receiving one or more Physical Downlink Shared Channel (PDSCH) signals corresponding to the one or more PDCCHs, and determining a PUCCH resource value nPUCCH(3,p) corresponding to a value of a transmit power control (TPC) field of a PDCCH for a PDSCH signal on a secondary cell (SCell) among a plurality of PUCCH resource values configured by a higher layer for the PUCCH format 3. If a single antenna port transmission mode is configured, the PUCCH resource value nPUCCH(3,p) indicated by the TPC field is mapped to one PUCCH resource for a single antenna port, and, if a multi-antenna port transmission mode is configured, the PUCCH resource value nPUCCH(3,p) indicated by the TPC field is mapped to a plurality of PUCCH resources for multiple antenna ports.
