Abstract

Selon la présente invention, un mode de réalisation de la présente invention concerne un procédé de réponse de message, comprenant les étapes suivantes : un premier dispositif de réseau sans fil reçoit des premières informations et des secondes informations envoyées par un second dispositif de réseau sans fil ; le premier dispositif de réseau sans fil détermine une première ressource occupée par un premier message de réponse correspondant aux premières informations et une seconde ressource occupée par un deuxième message de réponse correspondant aux secondes informations ; et lorsque la première ressource et la seconde ressource sont identiques, le premier dispositif de réseau sans fil envoie un troisième message de réponse au second dispositif de réseau sans fil selon une règle de réponse prédéfinie, le troisième message de réponse étant utilisé pour indiquer le premier message de réponse et/ou le deuxième message de réponse. De ce fait, un mode de réalisation de la présente invention concerne en outre un dispositif de réseau sans fil. Au moyen des modes de réalisation de la présente invention, un message de réponse est renvoyé lorsqu'une collision HARQ-ACK se produit, garantissant ainsi une transmission normale d'informations.
