Abstract
A method of controlling the data rate of a data transmission between an emitter and a receiver, wherein data rate adaptation control commands may be sent using a return path from the receiver to the emitter, which comprises monitoring at least one receiving condition at the receiver; determining at least one threshold on said receiving conditions to trigger data rate adaptation control commands; estimating the transmission time of the data rate adaptation control commands from the receiver to the emitter and adjusting the threshold on these receiving conditions to trigger data rate adaptation control commands based on said estimation of the transmission time from the receiver to the emitter. Accordingly, by continuously adjusting at least one said triggering threshold according to the variation of the transmission time of said data rate adaption commands, a more efficient data rate adaptation method is obtained minimizing the adaptation needs.
