The present invention is related to an error handling in transmission of information units in radio links and in particular it is related to an error handling using automatic repeat request (ARQ) and transmission of information units in mobile communication. To reduce the access delay of packet data services, the present invention uses different code ratings according to type II hybrid ARQ for different erroneous information units selected from a formatted block of information units before retransmission. Therefore erroneous information units of a block of information units, that have been transmitted, are selected and the set of selected erroneous information units is divided into a set of n subsets encoded with n code ratings. Advantageously, the retransmission of portions of the formatted block with different code ratings enhances the reliability of the retransmission.
