Abstract
A terminal is disclosed including a processor configured to map a phase tracking reference signal, PTRS, to at least one symbol used for an uplink shared channel; and a transmitter configured to perform transmission processing for the uplink shared channel and the PTRS, wherein the processor sets a reference for mapping the PTRS to a second symbol when the transmitter transmits a demodulation reference signal, DMRS, using a first symbol and the second symbol in the uplink shared channel. In other aspects, another terminal and a base station are also disclosed.
