Abstract

L'invention concerne des procédés et des systèmes permettant de traiter des trames de données dans un système de radiocommunications assurant la transmission de données par paquets. Des trames de données (A1, B1-B2) assorties de délais d'attente spécifiés sont soumises à une seconde couche de protocole (PL2) et segmentées en blocs de radiocommunication (Rb) pour la transmission aux utilisateurs (A,B) via une liaison hertzienne (L). Les blocs (Rb) qui ne sont pas reçus correctement sont à nouveau transmis. On enregistre le nombre de retransmissions pour déterminer le taux d'erreurs sur les blocs. Par ailleurs, un temps de transmission est estimé pour chaque trame de données (A1, B1-B2) dans la seconde couche de protocole. On vide les trames de données (A1, B1-B2) dont les temps de transmission excèdent un reliquat sur les délais d'attente correspondants. Les trames de données restantes sont ensuite programmées de manière à réduire au minimum le nombre de délais d'attente avant la transmission. Les trames de données vidées sont à nouveau soumises depuis une première couche de protocole (PL1) vers la seconde couche de protocole (PL2).
