Abstract

Les modes de réalisation de la présente divulgation concernent un procédé de transmission sans fil. Le procédé est exécuté par une station de base, et le procédé consiste à : selon des informations d'état de terminal d'un terminal, utiliser le niveau de qualité de service (QoS) d'un premier service correspondant aux informations d'état de terminal. De cette manière, le niveau de QoS peut s'adapter à l'état de terminal, ce qui permet d'obtenir un équilibre entre QoE et l'état de terminal du terminal par rapport à un mode dans lequel le niveau de QoS n'est pas mis à jour sur la base de l'état de terminal, ce qui permet d'améliorer l'expérience de l'utilisateur.
