In one aspect, a user terminal is disclosed including a processor that controls a mapping of a first demodulation reference signal (DMRS), having a fixed location regardless of a symbol duration of an uplink shared channel (PUSCH), controls a mapping of a second DMRS, which is allocated depending on the symbol duration of the PUSCH, and determines a location of the second DMRS if the second DMRS is allocated. The user terminal also includes a transmitter that transmits at least one of the first DMRS and the second DMRS.
