The present invention relates to a wireless communication system. In more detail, the present invention relates to a method for transmitting uplink control information in a wireless communication system operating in TDD, and a device for same. The method includes transmitting Hybrid Automatic Repeat request - Acknowledgement (HARQ) in a subframe n through Physical Uplink Control Channel (PUCCH), and a transmission power of the PUCCH relates to a method determined using a specific equation, and a device for same. The specific equation includes applying a modulo-4 operation to a difference between a downlink assignment index, DAI, number and a number of physical downlink control channels, PDCCHs, the DAI number corresponding to a value of a DAI in a PDCCH lastly detected within at least one subframe associated with the UL subframe in the cell according to a specifc UL-DL configuration, and the number of PDCCHs corresponding to a total number of scheduling-related PDCCHs detected within the at least one subframe associated with the UL subframe in the cell according to the specific UL-DL configuration. |
