Abstract

La présente demande concerne un procédé et un appareil de récupération de liaison sans fil, et appartient au domaine technique de la communication sans fil. Le procédé de récupération de liaison sans fil d'un mode de réalisation de la présente demande est le suivant : après avoir contrôlé qu'une première couche de fond de liaison de communication avec un premier dispositif réseau est désynchronisée, et avant de déterminer que la première liaison a échoué, un terminal sélectionne un premier support en réponse au contrôle selon lequel un résultat de mesure correspondant au premier dispositif réseau satisfait une condition de rapport ; envoie le résultat de mesure à l'aide du premier support.
