Abstract
Embodiments of this application disclose a wireless communication method and an apparatus. The method includes: determining a target MCS if a current MCS exceeds a predetermined threshold, where the target MCS is an MCS less than or equal to the predetermined threshold; mapping a PTRS to one or more symbols based on the target MCS; and sending, to a terminal device, the symbol to which the PTRS is mapped. through implementation of the embodiments of this application, when the current MCS exceeds the predetermined threshold, the target MCS that is less than or equal to the predetermined threshold may be determined, so that a density of a PTRS on a time-frequency resource can be flexibly determined based on the target MCS and an association relationship between an MCS threshold and a time domain density of a PTRS, thereby helping reduce resource overheads of the PTRS.
