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.
Claims7
A terminal comprising:
- 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.
A terminal comprising:
- a receiver configured to perform reception processing for a downlink shared channel;
- and
- a processor configured to determine at least one symbol to which a phase tracking reference signal, PTRS, is mapped in the downlink shared channel,
- wherein the processor determines that a reference for mapping the PTRS is a second symbol in the downlink shared channel when a demodulation reference signal, DMRS, is mapped to a first symbol and the second symbol in the downlink shared channel.
A base station comprising:
- a processor configured to map a phase tracking reference signal, PTRS, to at least one symbol used for a downlink shared channel;
- and
- a transmitter configured to perform transmission processing for the downlink shared channel and the PTRS,
- wherein a reference for mapping the PTRS is a second symbol in the downlink shared channel when the processor maps a demodulation reference signal, DMRS, to a first symbol and the second symbol in the downlink shared channel.
