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.
