A method for transmitting data on a physical shared channel, wherein a terminal uses a first physical shared channel to transmit data to a base station, the data being transmitted on a physical shared channel group comprising a set number of the first physical shared channels, and being transmitted as many times as the number of first physical shared channels. A first demodulation reference signal (DMRS) for the data is mapped, according to mapping information, to the symbols forming the physical shared channel group, and transmitted to the base station, the mapping information being information for mapping a second DMRS, for a second physical shared channel that comprises the same number of symbols as the number of symbols forming the physical shared channel group.
