1. A method for transmitting an uplink signal by a communication apparatus in a wireless communication system, the method comprising:
configuring a primary cell of a first time division duplex uplink-downlink (TDD UL-DL) configuration and a secondary cell of a second TDD UL-DL configuration wherein the second TDD UL-DL configuration is different from the first TDD UL-DL configuration; and as for a downlink signal requiring hybrid ARQ acknowledgement (HARQ-ACK) feedback within subframe #n−k of the secondary cell, transmitting acknowledgement information for the downlink signal in a subframe #n, 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, if the secondary cell is scheduled by the same cell, the specific TDD UL-DL configuration is a TDD UL-DL configuration having a smallest number of DL and special subframes among one or more TDD UL-DL configurations in which subframes configured as DL and S in the primary and secondary cells are all configured as DL and S, and if the secondary cell is scheduled by another cell, the specific TDD UL-DL configuration is the first TDD UL-DL configuration of the primary cell,TABLE 1TDD UL-DLSubframe nConfiguration01234567890——6—4——6—41——7, 64———7, 64—2——8, 7, 4, 6————8, 7, 4, 6——3——7, 6, 116, 55, 4—————4——12, 8, 7, 116, 5, 4, 7——————5——13, 12, 9, 8,———————7, 5, 4, 11, 66——775——77 —,TABLE 2Uplink-downlinkSubframe numberconfiguration01234567890DSUUUDSUUU1DSUUDDSUUD2DSUDDDSUDD3DSUUUDDDDD4DSUUDDDDDD5DSUDDDDDDD6DSUUUDSUUD where D denotes a DL subframe, S denotes a special subframe, and U denotes a UL subframe. |
