Title:

METHOD AND DEVICE FOR TRANSFERRING DATA ACCORDING TO AN ARQ-METHOD

Document Type and Number:

WIPO Patent Application WO2003001730

Kind Code:

A9

Abstract:

The invention relates to the use of an ARQ method, especially a hybrid-ARQ-method, in order to carry out a reliable packet orientated data transfer, preferably, using a mobile radio system. When requesting a transmission data packet for the bits of the retransmission data packet, a different rate adaptation model is used in comparison with the bits of corresponding originally sent data packets. A particular advantage of said method is that the bit-rate adaptation is carried out by dividing the bits which are to be transferred into a plurality of partial bit flows (A-C) with respectively separate bit rate adaptation (21-23).
