1. A device, comprising:
an input unit configured in such a way that a piece of state information, which characterizes a simulated state of a spatial arrangement of components of surroundings of a wireless communication network, is ascertained or provided;
a model-based ascertainment unit configured in such a way that the state information is provided as an input parameter to an input section of a machine-trained model, the state information is propagated by the machine-trained model, and at least one prediction of a piece of channel state information based on the machine-trained model, which characterizes a state of at least one radio channel between two communication modules of the wireless communication network, is provided in an output section of the machine-trained model;
a raytracer configured in such a way that at least one prediction of the at least one piece of channel state information based on the raytracer is ascertained as a function of the ascertained state information; and
a coordination unit configured in such a way that operation of the model-based ascertainment unit and of the raytracer is coordinated;
wherein the model-based ascertainment unit is configured in such a way that a confidence level for the at least one prediction based on the machine-trained model is ascertained using the machine-trained model, and wherein the device further comprises:
a post-processing unit of the coordination unit, the post-processing unit being configured in such a way that the raytracer is activated for ascertaining the prediction based on the raytracer, or the prediction based on the machine-trained model is provided as a function of the ascertained confidence level.
