Reference signal transmission method and transmission apparatus

A reference signal transmission apparatus, comprising:

• a processor, configured to determine a resource block offset of a frequency domain position of a phase tracking reference signal (PTRS) based on PTRS information, an identifier of the transmission apparatus, and first bandwidth, wherein the PTRS information comprises a frequency domain density or a frequency domain interval of the PTRS, and the first bandwidth is bandwidth scheduled by a network device for the transmission apparatus;
• and
• a transceiver, configured to perform transmission of the PTRS with the network device based on the resource block offset that is of the frequency domain position of the PTRS.

A computer readable storage medium, wherein a computer program is stored in the computer readable storage medium, and when the program is executed, the transmission method is implemented, comprising:

• determining a resource block offset of a frequency domain position of a phase tracking reference signal (PTRS) based on PTRS information, an identifier of a terminal device, and first bandwidth, wherein the PTRS information comprises a frequency domain density or a frequency domain interval of the PTRS, and the first bandwidth is bandwidth scheduled by a network device for the terminal device;
• and
• performing transmission of the PTRS with the network device based on the resource block offset of the frequency domain position of the PTRS.
