A method of operating a communications system which comprises a communication station (UEl) and a further station (BS), the stations having means (26, 10) whereby they can communicate with each other, and the communication station having buffer memory means (BUFl to BUFn) for storing data units in at least one queue. One of the stations (UEl, BS) has means (36) for estimating the transmission delay of at least one of the data units in the at least one queue, and means (30) responsive to the estimated transmission delay exceeding a threshold value for requesting permission from the further station (BS) to enable the communication station (UEl) to transmit at least one data unit to the further station (BS). The further station (i.e. the base station) will either "grant" the permission (in the form of an acceptance of using a certain rate, to transmit to a certain power level, or to transmit for a certain period of time).
L'invention concerne un procédé d'exploitation d'un système de communication comprenant une station de communication (UE1) et une autre station (BS), ces stations étant dotées de moyens (26, 10) leur permettant de communiquer entre elles, et la station de communication comprenant des moyens mémoire tampon (BUF1 à BUFn) destinés à stocker des unités de données dans au moins une file d'attente. Une des stations (UE1, BS) comprend un moyen (36) d'estimation du retard de transmission d'au moins une des unités de données dans la file d'attente au moins, et un moyen (30) sensible à un retard de transmission estimé dépassant une valeur seuil, servant à demander une permission à l'autre station (BS) pour permettre à la station de communication (UE1) de transmettre au moins une unité de données à l'autre station (BS). Cette autre station (à savoir, la station de base) "accorde" la permission (sous la forme d'une acceptation d'une certaine vitesse) de transmettre à un certain niveau de puissance, ou de transmettre pendant une certaine durée.
