Abstract
By reducing the packet size for C2X data transmission, it is possible to increase the transmission range and the number of transmitted data packets per unit time. By way of example, only component information items are transmitted, which can be converted into a full information item by the receiver using supplementary information items that come from a different source. In order to obtain the full information items, it is possible to utilize firstly transmission properties of the radio medium and secondly common information bases as determined by the system.
