Abstract

La présente invention concerne un procédé de communication sans fil, un dispositif terminal et un dispositif de réseau. Le procédé comprend les étapes suivantes : un dispositif terminal reçoit un élément de commande (CE) de commande d'accès au support (MAC) envoyé par un dispositif de réseau, le CE MAC comprenant une première représentation binaire et des informations d'indication d'état d'une première indication de configuration de transmission (TCI) ; chaque bit dans la première représentation binaire correspond à une valeur TCI dans des informations de commande de liaison descendante (DCI), et ce dernier sert à indiquer le nombre d'ID d'état TCI indiqués par une valeur TCI correspondante ; et les informations d'indication d'état TCI étant utilisées pour déterminer au moins un ID d'état TCI correspondant à la valeur TCI correspondant à chacun des bits.
