Abstract: A method for applying control to a vehicle. The method includes: receiving, by way of a second control unit of a second vehicle to which control is to be applied, a signal encompassing a message encrypted using a valid symmetrical key of a first control unit of a first vehicle; ascertaining, by way of the second control unit, a decryptability of the encrypted message using a valid symmetrical key of the second control unit or a symmetrical reserve key of the second control unit ascertained by way of the second control unit; ecrypting the encrypted message, depending on the ascertained decryptability, by way of the second control unit using the valid symmetrical key of the second control unit or the symmetrical reserve key of the second control unit; and applying control, based on the decrypted message, to the second vehicle to which control is to be applied.

Abstract: A computer-implemented method. The method includes: receiving, by a first terminal device, first information characterizing a resource configuration provided by a network device for a data exchange between a) the network device and at least one terminal device and/or b) at least two terminal devices, providing second information based on the first information via at least one sidelink transmission to at least one further terminal device.

Abstract: A method for authenticating a user terminal as a transmitter of a message transmitted in a wireless communication network having a plurality of spatially distributed user terminals, The message is transmitted from a first user terminal to at least one second and/or one third user terminal with the aid of a wireless communications connection. The message includes useful data, first user-terminal-specific and second user-terminal-specific authentication data. The first user terminal is authenticated as the transmitter of the message based on the first user-terminal-specific authentication data with the aid of the second user terminal, and/or based on the second user-terminal-specific authentication data with the aid of the third user terminal.

Abstract: A vehicle control system for controlling the movement of a group of vehicles that includes at least a first vehicle, a second vehicle following the first vehicle, and a third vehicle which in turn follows the second vehicle, via vehicle data, present at least within the group of vehicles, for controlling the mutually dependent movement of the vehicles. The vehicle control system includes a control level with multiple control devices that utilize the vehicle data for influencing a state of movement of the vehicles in a first network topology, and a communication level with multiple communication devices that transmit the vehicle data between the vehicles in a second network topology. At least one of the network topologies is set as a function of the other network topologies and/or of a performance of and/or a requirement for the control level and/or communication level, during operation of the vehicles.

Abstract: A method for operating an automated vehicle convoy includes periodically wirelessly transmitting messages from preceding participants of the automated vehicle convoy to respective following participants of the automated vehicle convoy, proceeding from the leading participant of the automated vehicle convoy. The messages include at least one piece of, in particular temporal, information from which a minimum distance between each following participant and the respective preceding participant is ascertained. The following participants of the automated vehicle convoy are guided corresponding to the ascertained minimum distance.

Abstract: Method for determining a first parameter characterizing a packet error rate of a wireless packet-based data transmission in a radiocommunication system, comprising the following steps: determining a second parameter characterizing a bit error rate, BER, based on at least one operating parameter of the radiocommunication system, determining the first parameter based on the second parameter and a third parameter which characterizes a number of bits per data packet.
