This application provides a positioning measurement method and an apparatus, and relates to the field of communication technologies. The method includes: A target device receives first indication information from a location management function (LMF), where the first indication information indicates a measurement time window, a positioning reference signal (PRS) resource within the measurement time window belongs to at least one frequency, and the at least one frequency includes a target frequency; and the target device performs first positioning measurement on a PRS resource on the target frequency within the measurement time window based on the first indication information. According to the foregoing solution, the LMF indicates, by using the first indication information, the target device to perform the first positioning measurement on the PRS resource on the target frequency within the measurement time window.
