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.

Abstract: This application provides a resource management method and apparatus. A terminal determines at least one reference signal resource corresponding to each of at least two frequency domain resources, and selects at least two reference signal resources from a plurality of reference signal resources corresponding to the at least two frequency domain resources, where the at least two selected reference signal resources are reference signal resources corresponding to at least two different frequency domain resources. In other words, some of the at least two reference signal resources are selected from a plurality of reference signal resources corresponding to one frequency domain resource, and other reference signal resources are selected from a plurality of reference signal resources corresponding to another frequency domain resource. In this way, the terminal can simultaneously receive data sent by a network device by using reference signal resources corresponding to different frequency domain resources, thereby improving communication efficiency.
