A communication apparatus comprises a means that performs error detections of N packet data units received in N transmission processes; a means that transmits an affirmative-response representative signal or a first retransmission request signal in accordance with a result of that error detection; a storing means that stores the packets, which are subjects of the affirmative response, in preparation for transfer to an upper-order layer; a means that, when the order of the packets that are the subjects of the affirmative response is intermittent, further confirms the necessity of retransmissions for the missing packets and then transmits a second retransmission request signal; and a means that corrects the order of the packet data units and transfers the packets from the storing means to the upper-order layer.
L~invention concerne un appareil de communication comprenant un moyen réalisant des détections d~erreur de N unités de données en paquet reçues dans N processus de transmission ; un moyen qui transmet un signal représentatif de la réponse affirmative ou un premier signal de demande de retransmission selon un résultat de cette détection d~erreur ; un moyen de stockage qui stocke les paquets, qui font l~objet de la réponse affirmative, en vue du transfert vers une couche de rang supérieur ; un moyen qui, lorsque l~ordre des paquets faisant l~objet de la réponse affirmative est intermittent, confirme encore la nécessité de retransmission pour les paquets manquants puis transmet un second signal de demande de retransmission ; et un moyen corrigeant l'ordre des unités de données en paquet et transfère les paquets du moyen de stockage à la couche de rang supérieur.
