Abstract: This application provides a wireless sensing method and an apparatus. The method includes: A first communication apparatus receives a first signal and a second signal based on a first transmission parameter set and a second transmission parameter set respectively, and performs sensing based on the first signal and the second signal, to obtain a sensing result. The first transmission parameter set corresponds to the first signal, at least one parameter in the first transmission parameter set meets a first condition, and the first condition is related to a targeted ranging coverage; and the second transmission parameter set corresponds to the second signal, at least one parameter in the second transmission parameter set meets a second condition, and the second condition is related to targeted sensing precision.

Abstract: A transmit end receives a first ranging parameter from a receive end, where the first ranging parameter is received in an Nth time of ranging, and the first ranging parameter includes first ranging precision of a ranging signal and/or a first signal-to-noise ratio of the ranging signal (S310). The transmit end determines a first ranging waveform based on the first ranging parameter (S320). The transmit end sends the first ranging waveform to the receive end (S330). The transmit end receives a second ranging parameter from the receive end, where the second ranging parameter is determined based on the first ranging waveform, the second ranging parameter includes second ranging precision of the ranging signal and/or a second signal-to-noise ratio of the ranging signal, and the second ranging precision is less than the first ranging precision (S340).

Abstract: A first communication apparatus determines a first frequency domain resource, where the first frequency domain resource is determined from a frequency domain resource pool based on a sensing requirement parameter. The first communication apparatus sends a sensing signal on the first frequency domain resource.

Abstract: A sensing method includes determining, by a first communication apparatus, first information. The first information indicates a pulse repetition interval (PRI). The sensing method also includes sending, by the first communication apparatus, the first information to a second communication apparatus. The first information is used by the second communication apparatus to send a reference signal, and a periodicity of the reference signal in time domain is less than or equal to the PRI. The sensing method further includes receiving, by the first communication apparatus, the reference signal from the second communication apparatus. The sending method additionally includes sensing, by the first communication apparatus, a to-be-sensed target based on the reference signal.

Abstract: A method for sensing sneezing based on a wireless signal includes obtaining a wireless signal, where the wireless signal propagates in space including a first object. Doppler estimation is performed on the wireless signal, to obtain Doppler information of the wireless signal. The Doppler information of the wireless signal may be used for indicating impact of the first object on a frequency of the wireless signal. Whether the first object is sneeze droplets is determined based on the Doppler information of the wireless signal.
