Abstract
A terminal apparatus for communicating with a base station apparatus, the terminal apparatus including: a multiplexing unit configured to map a PTRS signal generated based on a pseudo-random code to a resource element; and a transmitter configured to transmit a PUSCH, wherein the multiplexing unit maps the PTRS signal to a subcarrier based on at least an offset of a frequency position, a C-RNTI, the number of resource blocks to be scheduled, and a frequency density of the PTRS, and the transmitter transmits the PUSCH to which the PTRS is mapped.
Claims4
A terminal apparatus for communicating with a base station apparatus, the terminal apparatus comprising:
- multiplexing circuitry configured to map a phase tracking reference signal (PTRS) and a demodulation reference signal (DMRS) on resource elements;
- and
- transmission circuitry configured to transmit a physical uplink shared channel (PUSCH), wherein
- the multiplexing circuitry is configured to map the PTRS on a subcarrier position of a resource element based on at least a cell-radio network temporary identifier (C-RNTI) and a frequency density of the PTRS,
- the multiplexing circuitry is configured to map the DMRS on a resource element which is different from the resource element on which the PTRS is mapped, and
- the transmission circuitry is configured to transmit the PUSCH on which the PTRS is mapped.
A base station apparatus for communicating with a terminal apparatus, the base station apparatus comprising:
- reception circuitry configured to receive a physical uplink shared channel (PUSCH);
- and
- demultiplexing circuitry configured to demultiplex a phase tracking reference signal (PTRS) and a demodulation reference signal (DMRS) from the PUSCH, the PTRS and the DMRS being mapped on resource elements, wherein
- the PTRS is mapped on a subcarrier position of a resource element based on at least a cell-radio network temporary identifier (C-RNTI) and a frequency density of the PTRS, and the DMRS is mapped on a resource element which is different from the resource element on which the PTRS is mapped, and
- the reception circuitry is configured to receive the PUSCH on which the PTRS is mapped.
A communication method for a terminal apparatus for communicating with a base station apparatus, the communication method comprising the steps of:
- mapping a phase tracking reference signal (PTRS) and a demodulation reference signal (DMRS) on resource elements;
- and
- transmitting a physical uplink shared channel (PUSCH) on which the PTRS is mapped, wherein
- the PTRS is mapped on a subcarrier position of a resource element based on at least a cell-radio network temporary identifier (C-RNTI) and a frequency density of the PTRS, and the DMRS is mapped on a resource element which is different from the resource element on which the PTRS is mapped, and
- the PUSCH on which the PTRS is mapped is transmitted.
