A method is provided for transmitting uplink control information at a communication apparatus configured with a plurality of cells including a Primary Cell (PCell) and a Secondary Cell (SCell) in a wireless communication system operating in a Time Division Duplex (TDD) mode. The communication apparatus receives one or more downlink signals requiring Hybrid Automatic Repeat reQuest Acknowledgement (HARQ-ACK) feedback in a set of subframes. The communication apparatus transmits reception response information about the one or more downlink signals on a subframe configured for Scheduling Request (SR) transmission using one of a Physical Uplink Control CHannel (PUCCH) resources. The PUCCH resources include a HARQ PUCCH resource and a SR PUCCH resource.
