Method for data communication between at least two participants of a wireless communication system, corresponding control unit and transportation vehicle equipped with a control unit and a computer program

A transportation vehicle equipped with a control unit which performs a method for data communication between at least two participants of a wireless communication system, observing surroundings of a transmitting participant included in the at least two participants;

• determining position and motion of the at least two participants;
• estimating transmission conditions for a later point in time, wherein data ready for data communication stored in a transmit buffer of a participant is classified in different categories, the categories determining susceptibility of the data to transmission errors;
• selecting the category of data for data transmission from the transmit buffer at a given point in time for which the transmission conditions have been estimated based on the estimated transmission conditions so the data to be transmitted is in a category that fits the estimated transmission conditions, wherein in response to no data being found in a category that is susceptible enough against the amount of transmission errors under the estimated transmission conditions, a category of data which fits best to the estimated transmission conditions is selected;
• checking whether the transmission conditions are improved by link adaptation at the transmitting station;
• and
• transmitting the selected data according to the link adaptation.

A computer program comprising program operations which perform a method for data communication between at least two participants of a wireless communication system when the method is run in a computer, observing surroundings of a transmitting participant included in the at least two participants;

• determining position and motion of the at least two participants;
• estimating transmission conditions for a later point in time, wherein data ready for data communication stored in a transmit buffer of a participant is classified in different categories, the categories determining susceptibility of the data to transmission errors;
