Abstract

L'invention concerne un appareil et un procédé pour un système de communication sans fil destiné à synchroniser un encodeur (902) et un multiplexeur (910) jusqu'à une trame. Des files d'attente en suspens et actives (905, 912) sont situées entre l'encodeur et le multiplexeur. Des tâches (904) provenant de l'encodeur sont poussées dans la file d'attente en suspens, le multiplexeur détermine quelles tâches dans la file d'attente en suspens doivent être multiplexés dans la même trame. Puis, ces tâches appartenant à la même trame sont poussées dans la file d'attente active et multiplexées.
