Abstract

La présente demande concerne un procédé et un appareil de détermination de mode d'accès à un canal. Selon le procédé, un premier appareil reçoit une valeur d'évaluation de performance d'un premier mode d'accès à un canal, et détermine, en fonction de la valeur d'évaluation de performance, un mode d'accès à un canal d'une station (STA) à partir du premier mode d'accès à un canal et d'un second mode d'accès à un canal, le premier mode d'accès à un canal se référant à la détermination, au moyen d'un réseau neuronal, que la STA obtient un accès à un canal, le second mode d'accès à un canal se référant à la détermination, au moyen d'un accès multiple à détection de porteuse doté d'un évitement de collision, que la STA obtient un accès au canal, et la valeur d'évaluation de performance comprenant la précision et/ou une valeur de perte du réseau neuronal. Le premier appareil détermine, en fonction de la valeur d'évaluation de performance du premier mode d'accès à un canal, si le mode d'accès à un canal de la STA est le premier mode d'accès à un canal ou le second mode d'accès à un canal, de façon à aider la STA à déterminer d'obtenir un accès au canal dans un mode d'accès à un canal approprié, ce qui aide encore à augmenter le débit du système et à réduire le retard temporel de communication.
