Abstract: A method and apparatus for transmitting a physical uplink control channel (PUCCH) in a wireless communication system is provided. A machine-type communication (MTC) user equipment (UE) determines a PUCCH resource in a plurality of subframes. The PUCCH resource is subject to frequency hopping across the plurality of subframes regardless of a number of repetition of PUCCH transmission and a starting subframe of the PUCCH transmission. The UE transmits the PUCCH by using the PUCCH resource to a network.
