High speed data transmission in mobile communication networks

Abstract

The invention relates to high speed data transmission in digital mobile communication systems. In multichannel data transmission, a single data connection is allocated a plurality of parallel traffic channels (Ch1, Ch2, Ch3) via which the data units (1, 2, . . . , n) are transferred. At the transmitter (Tx), the data units are provided with a numbering by means of which the receiver (Rx) is able to restore the transmission sequence of the data units received via the different traffic channels. If the length of the data units varies to a great extent or is small in relation to the transmission delay tolerance of the traffic channels, the number space of the data units must be large for the receiver to be able to restore the data unit sequence. An increase in the number of numbering bits signifies a lower efficiency for the transfer. In at least embodiment of the invention, short data units are concatenated in data blocks (I and II) each of which is transmitted as an entity via the traffic channel. In each data block, advantageously only one data unit is numbered.
