Abstract: This application provides a sidelink quality measurement method and a communications apparatus. The method includes: A first terminal device sends a reference signal to a second terminal device, where the reference signal is used to determine channel state information of a first sidelink, and the first sidelink is a direct link from the first terminal device to the second terminal device. The first terminal device receives, from the second terminal device, the channel state information of the first sidelink.

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.

Abstract: A method for obtaining traffic information may be applied to an on-board unit. The method may include: receiving vehicle-to-everything (V2X) information, where the V2X information indicates a first group of lane identifiers and traffic information corresponding to each lane identifier in the first group of lane identifiers, and the first group of lane identifiers includes a first lane identifier; obtaining map information, where the map information indicates that a second lane identifier on a map and the first lane identifier correspond to a same lane; determining that a vehicle is on the lane corresponding to the second lane identifier; determining, based on the map information, that the vehicle is on the lane corresponding to the first lane identifier; and extracting traffic information corresponding to the first lane identifier from the V2X information.
