A hybrid ARQ method for packet data transmission in a mobile communication system wherein previously transmitted packets are combined with retransmitted packets, said packets being segmented into a plurality of protocol data units PDUs, each being assigned a sequence number for identification purposes. According to the invention the sequence number is transmitted on a control channel which is separate from the data channel for transmitting the PDUs.

Il s'agit d'une méthode ARQ hybride pour la transmission de données par paquets dans un système de communication mobile où les paquets transmis précédemment sont combinés aux paquets retransmis. Lesdits paquets sont segmentés en de multiples unités de données de protocole (PDU), à chacune étant affecté un numéro de séquence aux fins d'identification. Selon cette invention, le numéro de séquence est transmis sur un canal de commande distinct du canal de données qui sert à transmettre les PDU.
