Abstract

La présente invention concerne le domaine technique de la communication sans fil, en particulier un procédé, un système et un équipement pour le comptage d'une minuterie DRX et vise à obtenir le comptage de la minuterie DRX dans une scène dynamique TDD (duplex par répartition dans le temps). Le procédé de la présente invention : un équipement côté réseau détermine des informations pour le comptage de la minuterie DRX sur lequel l'équipement utilisateur doit être notifié, conformément au changement de configuration en duplex par répartition dans le temps (TDD) ; notifier l'équipement utilisateur des informations pour le comptage de la minuterie DRX afin de lui permettre de compter sur la minuterie DRX conformément aux informations pour le comptage de la minuterie DRX. Dans le mode de réalisation de la présente invention, l'équipement côté réseau notifie l'équipement utilisateur des informations pour le comptage de la minuterie DRX, afin de permettre à l'équipement utilisateur de réaliser le comptage sur la minuterie DRX, conformément aux informations sur le comptage de la minuterie DRX, ainsi, le comptage de la minuterie DRX est réalisé dans la scène dynamique TDD et les performances du réseau sont améliorées.
