Abstract: An information sending method, an information receiving method, a device, and an apparatus are disclosed. The information sending method includes: determining, by a first terminal device based on first information, at least one of a quantity or a position of m DMRSs carried on a PSSCH, where m is a positive integer, and the first information includes at least one of a subcarrier spacing, duration of the PSSCH, or a channel coherence time; and sending, by the first terminal device, the m DMRSs to a second terminal device. In addition, when the DMRS on the PSSCH is determined, a reference channel coherence time may be selected. For example, a time interval between two configured adjacent DMRSs may be less than or equal to the channel coherence time.
