摘要
Embodiments of this application provide a time-frequency resource allocation method and apparatus. The method includes: determining, by a network device, N terminal device types based on a current movement speed of a terminal device within a coverage area, where the N terminal device types are in a one-to-one correspondence with N demodulation reference signals (DMRSs) with different time domain densities; classifying, by the network device, available time-frequency resources into N time-frequency resource groups based on the N terminal device types, where a first DMRS in the N DMRSs is configured for a first time-frequency resource group in the N time-frequency resource groups; and sending, by the network device, resource indication information to the terminal device based on the N time-frequency resource groups.
