According to embodiments of the present invention, multiple frames or sub- frames on an uplink channel may be aggregated into one logical unit for demodulation and decoding to allow one data packet to span over multiple frames. Multi-frame aggregation is enabled by modifying the uplink resource allocation messages transmitted to the user terminals. The multi-frame resource allocation message includes a BEGIN FLAG field indicating whether a corresponding frame is the first frame in a multi-frame allocation and a REMAINING RESOURCES field to indicate the number of units (e.g., slots or frames) remaining in the multi-frame allocation.

Selon des modes de réalisation de la présente invention, de multiples trames ou sous-trames sur un canal de liaison montante peuvent être agrégées en une seule unité logique pour une démodulation et un décodage afin de permettre à un paquet de données de s'étaler sur de multiples trames. Une agrégation de trames multiples est rendue possible en modifiant les messages d'allocation de ressources de liaison montante transmis aux terminaux utilisateurs. Le message d'allocation de ressources à trames multiples comprend un champ DRAPEAU DE DÉMARRAGE indiquant si une trame correspondante est la première trame dans une allocation de trames multiples, et un champ RESSOURCES RESTANTES pour indiquer le nombre d'unités (par exemple, intervalles ou trames) restant dans l'allocation de trames multiples.
