Abstract

Des modes de réalisation de la présente divulgation concernent des dispositifs, des procédés, des appareils et des supports de stockage lisibles par ordinateur de mesure de rejet d'unité de données. Dans le procédé, un dispositif terminal reçoit une configuration en provenance d'un dispositif de réseau. La configuration indique une mesure de mesure associée à une mesure d'un rejet d'unité de données. Le dispositif terminal effectue la mesure du rejet d'unité de données sur la base de la configuration. Le dispositif terminal transmet, en termes de mesure de mesure au dispositif de réseau, la mesure du rejet d'unité de données. De cette manière, le dispositif de réseau peut être informé des données de mesure de l'unité de données rejetées en termes de la mesure. De telles données de mesure peuvent être avantageuses pour que le dispositif de réseau attribue des ressources pour le dispositif terminal.
