Abstract
The present disclosure relates to a method for transmitting an urgent message from a transmitting vehicle to at least one receiving vehicle via a radio network, while a normal message has already been outputted in a radio channel of the radio network by a subscriber of the radio network different from the transmitting vehicle. A transmitting circuit of the transmitting vehicle transmits the urgent message in the radio channel with a transmission level which is lower than a transmission level of the normal message. An associated receiving circuit of the at least one receiving vehicle receives a superimposition signal containing the normal message and the urgent message from the radio channel, extracts the normal message from the superimposition signal, determines a residual signal describing a difference between the superimposition signal and the extracted normal message, and reconstructs the urgent message on the basis of the residual signal.
