1. A method for transmitting an uplink signal by a communication apparatus in a wireless communication system, the method comprising:
receiving data within a subframe set, on a secondary cell of a first time division duplex uplink-downlink (TDD UL-DL) configuration, wherein the subframe set includes a subframe #n-k of the secondary cell; and transmitting acknowledgement information for the data in a subframe #n on a primary cell of a second TDD UL-DL configuration, wherein the second TDD UL-DL configuration is different from the first TDD UL-DL configuration, wherein k is an element of K: {k0, k1, . . . kM−1} of a specific TDD UL-DL configuration within a TDD UL-DL configuration set, wherein K: {k0, k1, . . . kM−1} is a parameter set defined by table 1, and the TDD UL-DL configuration set includes TDD UL-DL configurations defined by table 2, wherein, if the secondary cell is configured to be scheduled by the same cell, the specific TDD UL-DL configuration is a TDD UL-DL configuration having a smallest number of DL subframes among one or more TDD UL-DL configurations in which subframes configured as DL in the primary cell or the secondary cell are all configured as DL, and wherein, if the secondary cell is configured to be scheduled by another cell, the specific TDD UL-DL configuration is the second TDD UL-DL configuration of the primary cell,TABLE 1TDD UL-DLSubframe nConfiguration01230——6—1——7, 642——8, 7, 4, 6—3——7, 6, 116, 54——12, 8, 7, 116, 5, 4, 75——13, 12, 9, 8, 7, 5, 4, 11, 6—6——77TDD UL-DLSubframe nConfiguration45678904——6—41———7, 64—2———8, 7, 4, 6——35, 4—————4——————5——————65——77—,TABLE 2Uplink-downlinkSubframe numberconfiguration01234567890DSUUUDSUUU1DSUUDDSUUD2DSUDDDSUDD3DSUUUDDDDD4DSUUDDDDDD5DSUDDDDDDD6DSUUUDSUUD where D denotes a DL subframe, S denotes a special subframe, and U denotes a UL subframe. |
