摘要： A method for V2X communication. The method includes transmitting, via at least one V2X radio channel, at least one first V2X message object; receiving, via the at least one V2X radio channel, at least one feedback associated with a reception status of the at least one first V2X message object; deciding, based on the at least one feedback, whether to transmit at least one second V2X message object; and transmitting, via the at least one V2X radio channel, the at least one second V2X message object, if the decision indicates that the at least one second V2X message object is to be transmitted.

摘要： A method is described for the locationally selective transmission of a signal by radio. Both a transmitter and a receiver are synchronized to the same time reference. The receiver receiving and demodulating, at a time that is one of the specified times of the time reference, a signal transmitted by the transmitter, if the receiver has received the signal at a time that is one of the specified times. The method includes the transmitter determining a receive location within a receive zone to which it wishes to transmit the signal in selective fashion, a position in the receive zone being a function of a position of the transmitter and a signal runtime. The method also includes the transmitter transmitting the signal; and the receiver, which is situated inside the receive zone, receives and demodulates the signal.

摘要： 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.

摘要： A first terminal of a radio communications network. The first terminal includes at least one processor, at least one memory with computer program code, and at least one communication module and at least one antenna. The computer program code is configured in such a way that, using the processor, the communication module, and the antenna, it causes the first terminal to send first messages on a first radio resource to a group of further terminals, to receive at least one response, after sending the particular first message, from at least one of the further terminals of the group, to ascertain a resource change decision as a function of the at least one response, and to send second messages as a function of the resource change decision on a second radio resource to the group of further terminals, the second radio resource being different from the first radio resource.
