Abstract

La présente invention concerne un procédé de configuration pour transmission dynamique de liaison montante sans accord et un dispositif de communication. Le procédé comprend : un appareil de réseau générant des DCI pour activer ou désactiver une configuration d'accord configurée, les DCI comprenant un premier champ d'indication et un ou plusieurs premiers champs de type, le premier champ d'indication indiquant un indice d'une configuration d'accord configurée à activer ou désactiver, le nombre de bits dans les premiers champs de type étant associé à la configuration d'accord configurée à activer ou désactiver, et le premier champ d'indication étant situé avant tous les premiers champs de type ou dans une position d'extrémité des DCI ; et l'appareil de réseau envoyant les DCI à un appareil terminal, de telle sorte que l'appareil terminal active ou désactive la configuration d'accord configurée correspondant à l'indice selon les DCI. L'invention place le premier champ d'indication avant les premiers champs de type ou dans la position d'extrémité des DCI, de telle sorte que le premier champ d'indication a une position fixe dans les DCI. L'appareil terminal peut effectuer une analyse pour obtenir le premier champ d'indication sur la base de la position fixe, et déterminer si la configuration d'accord configurée doit être activée ou désactivée.
