Abstract: This application provides a signal processing method and device. The method includes: A first device receives a first complex signal formed after an electromagnetic signal is reflected by an ambient environment. A dimension of the first complex signal is related to configuration information of the first device. The first device sends a transformed signal to a second device. The transformed signal includes a transformed bitstream, and the transformed bitstream is obtained by the first device by transforming the first complex signal based on the configuration information of the first device, so that the second device de-transforms the transformed signal based on the configuration information of the first device to obtain a second complex signal.

Abstract: A wireless local area network sensing method. The method includes: in a process in which a second network device performs high frequency MIMO channel access, a first network device sends indication information to a plurality of second network devices, where the indication information indicates the plurality of second network devices to send uplink sensing signals; and the first network device receives the uplink sensing signals from the second network devices and performs uplink sensing based on the uplink sensing signals.
