Abstract
This application provides a reference signal transmission method and transmission apparatus. The transmission method includes: obtaining, by a network device, reference information of a terminal device, where the reference information includes at least one of an identifier of the terminal device and scheduling information of the terminal device; determining, by the network device, a transmission parameter of a phase tracking reference signal (PTRS) of the terminal device based on the reference information, where the transmission parameter includes at least one of a sequence of the PTRS and a frequency domain position of the PTRS; and transmitting, by the network device, the PTRS with the terminal device based on the transmission parameter. According to the reference signal transmission method and transmission apparatus provided in embodiments of this application, interference to the PTRS can be randomized.
