Abstract
A first on-board terminal for radio communication in a radio network. The first on-board terminal is designed to retransmit first data via the radio channel after the expiration of a second time period, which begins after the end of the previous transmission of the first data, if the radio channel is not occupied after the expiration of a first time period.
Claims5
A second on-board terminal for radio communication in a radio network, the second on-board terminal being configured to:
- ascertain an identifier, which identifies a first on-board terminal as a predecessor for a transmission of second data;
- receive first data via a radio channel from the first on-board terminal that includes the identifier;
- ascertain second data;
- await a time period after an end of the reception of the first data;
- and
- transmit the second data via the radio channel if the time period has expired;
- wherein the radio channel is a dedicated radio channel which is reserved exclusively for transmitting, by a number of different terminals, consecutive packets according to a packet train, the packet train including a number of data not immediately succeeding one another, and which originate from the different terminals, and for which only a first of the different terminals has carried out a channel access procedure;
- wherein at least three different terminals including the second on-board terminal, transmit data in the packet train on the dedicated radio channel.
