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.

Abstract: A communications method and device, to reduce service interruption time and signaling overheads that are generated when an access point that provides a communication service for a station changes because the station moves or changes a direction. First frames sent by different access points in an access point set to a station include a same sending address. In this way, when the station moves or changes a direction, the access point that provides the communication service for the station changes from one access point in the access point set to another access point. Because first frames sent by access points in the access point set include a same sending address, the station may consider the access point set as one access point.
