Method and Radio Communication System for an Industrial Automation System

A radio communication system for an industrial automation system includes at least one first communication device operated as a radio base station, and several second radio communication devices operated as radio subscriber stations, wherein the first communication device is arranged or movable on a vehicle, where the first communication device and the second communication devices can be assigned to a group of communication devices and can only be connected to one another in a wireless manner within the same group of communication devices, where the first communication device and the second communication devices detect within their assigned communication device group distances between the first communication device and the respective second communication device, on the basis of signal strength measurement values or position data and where, depending on the detected distances, the first communication device allocates radio resources for a radio communication with the respective second communication device.
