Abstract: This application provides an information transmission method and apparatus. The method includes: determining a time domain density of a phase tracking reference signal PTRS; determining a frequency domain density of the phase tracking reference signal PTRS based on available bandwidth, or determining a frequency domain density of the phase tracking reference signal PTRS based on a scheduled resource block RB or an available resource block RB; mapping the PTRS to one or more orthogonal frequency division multiplexing OFDM symbols based on the time domain density and the frequency domain density; and sending a signal that includes the OFDM symbol to which the PTRS is mapped. The corresponding apparatus is also disclosed. When the technical solution of this application is used, a quantity of PTRSs can be prevented from jumping when a value of scheduled bandwidth is close to a threshold, both accuracy of common phase error estimation and spectral efficiency are taken into consideration, and the PTRSs can be uniformly mapped in the scheduled or available bandwidth, thereby properly configuring the PTRSs.
