Abstract: Embodiments of this application provide a sensing signal sending method, a sensing signal receiving method, and an apparatus. The method includes: A first communication device determines first time domain resource configuration information based on a speed resolution and a maximum unambiguous speed that are related to a target object, and sends a sensing signal to a second communication device at a plurality of sending moments that are on a time domain resource and that are indicated by the first time domain resource configuration information, so that the second communication device calculates a speed of the target object based on the sensing signal.

Abstract: An environmental imaging method includes: A first device sends first indication information to a second device, where the first indication information indicates a first spatial location at which the second device is to send a measurement signal, and the first spatial location is evenly distributed in an azimuth direction and/or at an azimuth angle; the first device receives an echo signal, where the echo signal is a signal formed by reflecting, by a target, the measurement signal sent by the second device after the measurement signal arrives at the target; and the first device performs imaging on the target based on the echo signal. The method may be implemented in a system or an apparatus.

Abstract: This application provides a signal transmission method and apparatus. The method includes: obtaining, by a transmitter side, a first signal with N points; performing signal separation on the first signal with N points, to obtain two groups of signals (for example, a second signal with N points and a third signal with N points); determining four signals with N/2 points based on the two groups of signals obtained through separation, and combining the four signals with N/2 points, to obtain a to-be-sent signal with 3N/2 points; and sending the signal with 3N/2 points to a receiver side, to enable the receiver to restore the first signal with N points from the received signal with 3N/2 points.
