Abstract
A wireless communication method includes: sending first indication information to a network device, wherein the first indication information is used to indicate at least one of a modulation and coding scheme threshold that corresponds to a pattern of a phase tracking reference signal and recommended by a terminal device, a scheduled resource block quantity threshold that corresponds to the pattern of the phase tracking reference signal and recommended by the terminal device, and a factor of impact of phase noise of the terminal device on a signal received by the terminal device; and receiving the phase tracking reference signal sent by the network device.
