The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting an uplink signal in a wireless communication system supporting a carrier merge, and comprises the steps of: setting a first cell having a first TDD UL-DL configuration and a second cell having a second TDD UL-DL configuration; receiving a PHICH signal in a subframe #(n- L ) of the first cell, or receiving a PDCCH signal in a subframe #(n-K) of the first cell; and transmitting a PUSCH signal in a subframe #n of the second cell, corresponding to the PHICH signal or the PDCCH signal, wherein the relationship between the subframes #(n- L ), #(n-K), and #n is determined in consideration of a parameter value set in a specific TDD UL-DL configuration inside a TDD UL-DL configuration set, and the specific TDD UL-DL configuration is the TDD UL-DL configuration having the least number of UL subframes from one or more TDD UL-DL configurations, in which subframes set as UL in the first cell or the second cell are all set as ULs. |
