Abstract: A method for transmitting, by a user equipment, uplink control information, and a user equipment therefore are discussed. The method according to one embodiment includes determining respective first acknowledgement, negative acknowledgement or discontinuous transmission (ACK/NACK/DTX) responses for four downlink (DL) subframes of a first carrier and respective second ACK/NACK/DTX responses for four DL subframes of a second carrier; and transmitting ACK/NACK information representing the first and second ACK/NACK/DTX responses through the first or second carrier in an uplink (UL) subframe. For a same sequence of the first ACK/NACK/DTX responses for the four DL subframes of the first carrier, a same ACK/NACK information is transmitted when a sequence of the second ACK/NACK/DTX responses for the DL subframes of the second carrier is ‘ACK, ACK, ACK, ACK’ and when the sequence of the second ACK/NACK/DTX responses for the DL subframes of the second carrier is ‘ACK, DTX, DTX, DTX’.

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.
