Abstract

Des modes de réalisation de la présente demande concernent un procédé et un dispositif de communication sans fil. Le procédé est appliqué à un dispositif terminal, et le dispositif terminal est alimenté par un premier dispositif. Le procédé comprend les étapes suivantes : un dispositif terminal détermine une cause de défaillance pour une liaison cible ; et le dispositif terminal envoie à un second dispositif la cause de défaillance pour la liaison cible et/ou une requête correspondant à la cause de défaillance pour la liaison cible. De cette manière, la transmission de données normale du dispositif terminal peut être assurée.
