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 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 data transmission method and apparatus, and relates to the communication field. In the method, after obtaining a path parameter of each of at least one communication path between a first device and a second device, the first device may demodulate first data based on a pilot and the path parameter of each communication path. In other words, when demodulating the first data, the first device may refer to not only the pilot but also the path parameter of each communication path. The path parameter of each communication path can assist in demodulating the first data. When the path parameter of each communication path assists in demodulating the first data, there may be no need for too many pilots. Therefore, a resource occupied by the pilot can be reduced.

Abstract: Example communication methods and apparatus are described. In one example method, a terminal device obtains and sends first information, where the first information indicates non-differential information of at least one first target point at a first moment. The terminal device obtains second information and sends the second information, where the second information indicates differential information of at least one second target point, and each of the at least one second target point corresponds to a first target point in the at least one first target point. Differential information of each of the at least one second target point is determined based on non-differential information of the second target point at a second moment and non-differential information of a corresponding first target point at the first moment, and each of the at least one second target point is a target point sensed by the terminal device at the second moment.
