Abstract

L'invention concerne un procédé et un système de mise en oeuvre d'une demande de répétition automatique (ARQ) fondée sur une demande de répétition automatique hybride (H-ARQ) dans un système de communication sans fil. Lorsqu'une erreur de passage d'un accusé de réception négatif d'une H-ARQ (NACK) à un accusé de réception positif d'une H-ARQ (ACK) survient, le récepteur H-ARQ envoie un indicateur d'erreur NACK-à-ACK de la H-ARQ à l'émetteur H-ARQ à moins qu'une limite de retransmission maximale n'ait été atteinte, qu'un délai maximal d'acheminement n'ait expiré ou qu'une durée de vie du paquet dont la transmission a échoué ne soit arrivé à son terme. L'émetteur H-ARQ envoie un NACK local à l'émetteur ARQ de façon à récupérer à un niveau de l'ARQ le paquet dont la transmission a échoué. Le récepteur H-ARQ envoie un NACK local au récepteur ARQ si le récepteur H-ARQ ne reçoit pas le paquet dont la transmission a échoué avant l'avènement de certaines conditions. Le récepteur ARQ peut envoyer un raport d'état à l'émetteur ARQ en vue de récupérer le paquet dont la transmission a échoué.
