[0081] When the resource configuration information is configured by the second device, the second device may determine the resource configuration information for the signal based on the distance resolution or distance accuracy and the comb configuration parameters of the integrated communication and perception signal. Specifically, if the perception target is not recognized, the second device may determine the allocated perception resources based on the distance accuracy, maximum detection range, and the comb configuration parameters to ensure the accuracy of parameter estimation during the target object recognition process.

Specifically, if a sensing target is not identified, the first device may determine the allocated sensing resources based on the distance accuracy, maximum detection range, and the comb configuration parameters to ensure the accuracy of parameter estimation during target object identification.

[0090] When a perception target is identified, the first device determines the allocated perception resources based on the range resolution, maximum detection range, and the comb configuration parameters. Range resolution is the ability to distinguish between two or more targets at the same location but at different distances, and can affect the recognition probability and distance estimation accuracy in multi-target scenarios. Therefore, when a perception target is identified, allocating perception resources based on range resolution can ensure multi-target recognition probability and target recognition distance accuracy.

Range resolution is the ability to distinguish between two or more targets at the same location but at different distances, and can affect the recognition probability and distance estimation accuracy for multiple targets. Therefore, allocating sensing resources based on range resolution can ensure multi-target recognition probability and target recognition distance accuracy.
