The invention relates to packet transfer over a radio path in accordance with the ARQ protocol. It is based on the idea that instead of repeating in the retransmission the same bursts, i.e. the same information contained in the bursts in the same order, the order of the information is changed. This is done in such a way that the retransmission is not sent from one retransmission to another similarly interleaved, but the interleaving is changed. As a result, the content of the part that was incorrectly received in the previous transmission has been transferred to a new location. Hence, when the soft values of the channel corrector are combined, the probability of correct reception of this part in the retransmission greatly increases. Thereby the probability for error-free detection of the entire data packet notwithstanding the interference in the radio path is high.
