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.

Abstract: This application provides a method and an apparatus for determining a phase tracking reference signal (PTRS) pattern. The method includes: A terminal device receives first scheduled bandwidth threshold information from a network device, where a first scheduled bandwidth threshold indicated by the first scheduled bandwidth threshold information meets a first condition, and the first condition is that a ratio of a total quantity of modulation symbols in a PTRS pattern determined based on the first scheduled bandwidth threshold to a quantity of subcarriers in scheduled bandwidth is less than or equal to a first threshold; and determines a PTRS pattern on one orthogonal frequency division multiplexing (OFDM) symbol in an OFDM signal based on the scheduled bandwidth threshold. In this application, the network device configures, for the terminal device, the scheduled bandwidth threshold that meets the first condition, to ensure demodulation performance of the device.
