Abstract: A communication method includes receiving, by a terminal device, first information from a network device. The first information indicates a precoding matrix. The communication method also includes determining, by the terminal device, the precoding matrix based on the first information. The precoding matrix is for sending an uplink signal. The precoding matrix is determined based on a first matrix and a second matrix. At least one of the first matrix is determined from a first matrix set based on the first information, wherein the first matrix set is determined based on a horizontal-dimension parameter of an antenna of the terminal device; or the second matrix is determined from a second matrix set based on the first information, wherein the second matrix set is determined based on a vertical-dimension parameter of the antenna.

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: Embodiments of the present invention disclose a data processing method and apparatus, and belong to the field of communications technologies. The method includes: generating a physical layer protocol data unit PPDU, where the PPDU includes a preamble field, a data field, and a middle preamble field, and the preamble in the PPDU includes information used to indicate an insertion frequency of the middle preamble in the data field in the PPDU; and sending the PPDU. The insertion frequency of the middle preamble in the data field is indicated by using a specified field in the preamble. In this way, in different scenarios, the middle preamble may be inserted into the data field at different frequency, thereby reducing overheads of an inserted pilot and improving data transmission performance.
