Abstract: A method and system for determining, at a given instant, an optimal reception configuration and an optimal duration of a time interval is provided. The method comprises a first step of initializing a probability of reception associated with each of the different signals and further comprises the following iterative steps: a second step of determining two sets of signals, a third step of determining associated with each reception configuration, an optimal duration during which to use this configuration, a fourth step of determining, the optimal reception configuration of the values of the reception parameters, and steps of new probabilities of reception of the signals.
