Abstract[English]
According to an aspect, there is provided an apparatus for performing the following The apparatus receives, from an access node, a radio link failure, RLF, prediction mode of a machine-learning, ML, algorithm for predicting future RLFs in uplink, UL, and downlink, DL, directions based at least on values of one or more radio link quality metrics. The RLF prediction mode is one of: an UL-DL mode for RLF prediction in both UL and DL directions, an UL mode for RLF prediction in a UL direction or a DL mode for RLF prediction in a DL direction. The apparatus performs RLF prediction using the received RLF prediction mode of the ML algorithm. The apparatus transmits, to the access node, a prediction report comprising at least some of results of the RLF prediction.[French]
Selon un aspect, l'invention concerne un dispositif permettant de mettre en œuvre les opérations suivantes. Le dispositif reçoit, à partir d'un nœud d'accès, un mode de prédiction de défaillance de liaison radio (RLF) d'un algorithme d'apprentissage automatique (ML) permettant de prédire les futures défaillances de liaison radio dans les directions montante (UL) et descendante (DL) sur la base au moins d'une ou plusieurs mesures de qualité de liaison radio. Le mode de prédiction RLF est l'un des suivants : un mode UL-DL pour la prédiction RLF dans les directions UL et DL, un mode UL pour la prédiction RLF dans une direction UL ou un mode DL pour la prédiction RLF dans une direction DL. L'appareil met en œuvre une prédiction RLF à l'aide du mode de prédiction RLF reçu de l'algorithme ML. L'appareil transmet au nœud d'accès un rapport de prédiction comprenant au moins un des résultats de la prédiction RLF.
