10. A user equipment (UE) for transmitting a physical uplink shared channel (PUSCH) based on a shared demodulation reference signal (DM-RS), the UE comprising:
a controller configured to configure a sPUSCH (short physical uplink shared channel) based on a short Transmission Time Interval (sTTI) in one subframe and configure a shared DM-RS in a symbol included in some short TTIs among a plurality of short TTIs included in one subframe; and
a transmitter configured to transmit the sPUSCH to the base station,
wherein, the UE receives configuration information related to a position of the short TTI including the shared DM-RS and a position of the shared DM-RS in the short TTI from the base station, and the UE dynamically configures the position of the short TTI including the shared DM-RS and the position of the shared DM-RS in the short TTI according to the received configuration information.
