Abstract

Les modes de réalisation de la présente invention concernent un procédé et un appareil d'ajustement de valeur seuil pour avance temporelle. Au cours du procédé, un dispositif terminal transmet des premières informations de référence et reçoit d'un dispositif de réseau une première valeur seuil de qualité de signal sans fil qui est déterminée en fonction des premières informations de référence. La présente invention permet l'ajustement d'une valeur seuil de qualité de signal sans fil sur la base d'informations de référence rapportées, ce qui évite le problème de l'asynchronisation d'horloges entre le dispositif terminal et un réseau.
