Abstract
A reference signal transmission method and transmission apparatus performing the method are described. The transmission method includes determining a resource block offset of a frequency domain position of a phase tracking reference signal (PTRS) of a terminal device based on PTRS information of the terminal device, an identifier of the terminal device, and first bandwidth. The PTRS information includes a frequency domain density or a frequency domain interval of the PTRS, and the first bandwidth is bandwidth scheduled by the network device for the terminal device. The network device transmits the PTRS with the terminal device based on the resource block offset of the frequency domain position of the PTRS. The described reference signal transmission method embodiments are helpful in randomizing PTRS interference.
