Abstract: Example signal transmission methods, apparatuses, systems, and computer storage media are disclosed. One example method includes obtaining, by a first detection apparatus, a first moment, where the first moment is a start moment of a first time unit, and the first time unit is used for the first detection apparatus to send a first signal. The first signal is sent by the first detection apparatus based on a first periodicity, where the first signal is used to indicate sending resource information of a detection signal, and the first time unit is further used for a second detection apparatus to receive the first signal.

Abstract: A target detection method includes a radar apparatus that performs at least one interference sensing on a plurality of first time domain resources and determines a second time-frequency resource used for target detection in a first time-frequency resource based on a result of the at least one interference sensing. The first time domain resources are a subset of time domain resources corresponding to a time-frequency resource of a first detection apparatus, and the first time-frequency resource is the time-frequency resource of the first detection apparatus.

Abstract: A radar signal sending method and a device provides for the sending of the radar signal to cooperative radars. A first time domain range in L time domain ranges is determined. A first radar signal is sent in the first time domain range. Any one of the L time domain ranges partially overlaps at least one of the other (L−1) time domain ranges, and an absolute value of a difference between time domain start locations of any two of the L time domain ranges is greater than or equal to a first threshold and less than or equal to a second threshold.

Abstract: A method for detecting a target object implemented by a detection apparatus, where the detection apparatus transmits a radio signal on a frequency band on which mutual interference can be avoided to avoid or reduce interference caused by a transmit signal or a related signal of any detection apparatus when another detection apparatus determines a target. The detection apparatus divides a frequency band or a frequency domain raster based on a determined threshold to allow partial overlapping between frequency bands or rasters.

Abstract: This application relates to the field of wireless communications and self-driving/intelligent driving/autonomous driving vehicles, and in particular, to the field of collaborative radars. A first apparatus receives first information from a second apparatus. The first apparatus determines, based on the first information, the priorities of a plurality of time-frequency resources included in a first time-domain range. The first apparatus further selects a first time-frequency resource among the plurality of time-frequency resources. The priority of the first time-frequency resource is the highest among the priorities of the plurality of time-frequency resources. A time-frequency resource with a comparatively high priority is selected to send a radar signal, to reduce a probability of a resource collision, and reduce and/or avoid interference between radars, especially collaborative radars.

Abstract: A frequency band state determining method and a related device are provided. The method includes: A detection apparatus determines an intermediate frequency signal based on a detected interfering signal in an environment and an oscillation signal that belongs to a first frequency band. The detection apparatus performs first processing on the intermediate frequency signal, to obtain a first detection result, and when the first detection result indicates that the first frequency band is busy, the detection apparatus performs second processing on the intermediate frequency signal, to obtain a second detection result. The detection apparatus determines a state of the first frequency band based on the second detection result. The detection apparatus may be a radar, and the radar may work in a use scenario of a cooperative radar.
