Abstract	This paper deals with the application of Hybrid Automatic Repeat reQuest (h-arq) techniques to allow reliable data communications in wireless 3G networks. Basically, retransmission of coded data is endowed with soft combining schemes applied, respectively, to packet replicas, or to decoding algorithm outputs. In particular, the proposed coding scheme takes advantage of error correction capabilities of the turbo codes, while the combining algorithm follows the diversity approach. The performance of the proposedh-arq schemes has been derived by means of a suitable analytical approach and numerical simulations in the case of a typical umts environment. The results highlight the good behavior of the proposed scheme in term of error rate, throughput, packet delivery delay and power reduction.Cet article propose l’utilisation d’une technique hybride de correction d’erreur par détection et répétition (h-arq) permettant de fiabiliser les communications de données dans les réseaux radiomobiles de troisième génération. La retransmission des données codées est assurée à l’aide de schémas de combinaisons souples, appliqués d’une part aux répétitions des paquets de données, et d’autre part aux sorties de l’algorithme de décodage. En particulier, le schéma de codage proposé tire parti des capacités de correction des turbocodes et l’algorithme de combinaison est issu des techniques de diversité. Les performances de la techniqueh-arq ont été obtenues par une méthode analytique adaptée et par des simulations numériques d’un environnement umts typique. Les résultats soulignent le bon comportement de la solution proposée en terme de taux d’erreur, de débit utile, de temps de retard des paquets et de réduction de la puissance consommée.
