Abstract
In a packet data transmission via a radio interface of a communication system, a packet number as identification information is transmitted for every data packet between data stations communicating with one another. To improve transmission security for the identification information, the identification information is multiplied and distributed separately to at least two data packets or transmitted separately in a separate information data packet.
