Abstract: A user equipment (UE) is provided in a long term evolution (LTE) frequency division duplex (FDD) system. The UE receives a downlink control information (DCI) including a UL grant for transmitting the UL signal in an N-th subframe, and transmits the UL signal using the UL grant, in at least one of an (N+4)-th subframe and an (M+4)-th subframe. An M-th subframe is a subframe in which both of a physical downlink control channel (PDCCH) and an enhanced PDCCH (EPDCCH) are not transmitted. N and M are integers, and M is greater than N.
