Abstract: A first device sends a first message to a second device, where the first message indicates to the second device to hop to different channels at different times to send radio signals. The frequency bandwidth ranges of any two channels do not completely overlap, and the frequency bandwidth range of each channel is within a total frequency bandwidth range supported by the first device. The first device separately receives the radio signals that are sent by the second device on different channels at different times. The radio signals reach the first device after being reflected by an intermediate object. The first device measures the state information of the intermediate object based on the physical characteristics of the different radio signals that are separately received.

Abstract: This application provides a method and an apparatus for sensing measurement. In a technical solution of this application, a transmit end of data may send an indication frame to a receive end of the data, where the indication frame may indicate a spatial mapping matrix used by the transmit end of the data to send the data to the receive end of the data. In this way, the receive end of the data can eliminate impact of spatial mapping on channel state information based on the spatial mapping matrix, to obtain actual channel state information, thereby completing sensing, positioning, and the like on an ambient environment or a passive target by using the obtained actual channel state information.
