摘要： 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).

摘要： A method is provided for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information at a User Equipment (UE) in a wireless communication system. The UE is configured to use a Physical Uplink Control Channel (PUCCH) format 3 for the transmission of the ACK/NACK information. A PUCCH format between a PUCCH format 1a/1b and the PUCCH format 3 is determined for transmission of the ACK/NACK information for downlink transmission in a downlink frame set including M downlink subframes is to be transmitted, where M≥1, in one uplink subframe, according to whether at least one of specific conditions is met. The ACK/NACK information is transmitted using the determined PUCCH format in the one uplink subframe. The ACK/NACK information is transmitted by using the PUCCH format 1a/1b, when at least one of the specific conditions is met. One serving cell is configured for the UE.
