1. A method for transmitting an acknowledgement/not-acknowledgement (ACK/NACK) of User Equipment (UE) for which a plurality of serving cells have been configured, the method comprising:
receiving data in at least one of a subframe n of a second cell and a subframe n of a third cell; and
transmitting an ACK/NACK signal for the data in a subframe n+k of a first cell,
wherein the first cell uses a Frequency Division Duplex (FDD) radio frame,
wherein each of the second cell and the third cell uses a Time Division Duplex (TDD) radio frame,
wherein the k is a predetermined value,
wherein uplink (UL)-downlink (DL) configuration information about the TDD radio frame used in each of the second cell and in the third cell is received in the UE, and
wherein the UL-DL configuration information indicates any one of UL-DL configurations shown in a table below
