At least one radiation pattern is rotated at a first radio station for the purpose of sampling a predefined angular range. At a first time of rotation, a second radio station is detected with a first angular position within the angular range corresponding to the first time. The second radio station determines a first quality value which can be assigned to the first angular position and reports the first quality value back to the first radio station. The first quality value is available for evaluation at the first radio station at a second time corresponding to a second angular position of the radiation pattern. The first radio station controls the speed of rotation of the at least one radiation pattern for subsequent rotations so that the first angular position corresponds to the second angular position.
