Abstract

L'invention concerne des procédés et des systèmes de commande d'accès à un support sans fil. Selon certains aspects, un point d'accès peut ne pas autoriser des stations à désactiver des transmissions de liaison montante multi-utilisateurs. Le point d'accès peut en outre commander l'accès au support en désactivant l'accès par le biais d'un accès à un canal distribué amélioré (EDCA). Avec cette approche, un point d'accès peut améliorer la commande de l'accès à un canal par l'intermédiaire, par exemple, de transmissions en liaison montante déclenchées et non par l'intermédiaire d'un accès en mode contention par des stations.
