Abstract: A method is provided for receiving a signal by a user equipment (UE) using time division duplex (TDD) in a wireless communication system. The UE receives uplink (UL) grant information on a first cell, the UL grant information scheduling a UL transmission on a second cell. The UE transmits UL data in a UL subframe on the second cell via a physical UL shared channel based on the UL grant information. The UE receives hybrid automatic repeat and request acknowledgement (HARQ-ACK) information in a downlink (DL) subframe on the first cell. The first cell and the second cell have different TDD UL-DL configurations. The DL subframe on the first cell is determined based on a TDD UL-DL configuration of the second cell.

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.

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 is presented for transmitting an Acknowledgement/Negative Acknowledgement (ACK/NACK) information at a User Equipment (UE) configured to use Physical Uplink Control Channel (PUCCH) format 3 in a wireless communication system. The UE determines that transmission of a scheduling request is configured in one uplink subframe in which a transmission of ACK/NACK information for downlink transmission in a downlink subframe set including one or more downlink subframes is to be transmitted. The UE transmits the ACK/NACK information and the scheduling request using PUCCH format 1b in the one uplink subframe, when transmission of the ACK/NACK information coincides with the one uplink subframe for the transmission of the scheduling request and at least one of specific conditions is met, (e.g., the ACK/NACK information corresponds to one Semi-Persistent Scheduling (SPS) release Physical Downlink Control Channel (PDCCH) having a Downlink Assignment Index (DAI) value of 1 in the downlink subframe set).
