Abstract
A method for data transmission between a transmitter and a receiver in a digital mobile communication system comprising at least one mobile station and at least one air interface, in which method the data to be transmitted is assembled into frames comprising at least a header and a data portion; and frames are transmitted only when there is need for data transmission; an extra information field is added to the data portion of a frame and the transmitter and the receiver negotiate between themselves an algorithm and/or a parameter on the basis of which the contents of the extra information field are formed.
