Abstract

La présente invention se rapporte au domaine des communications. La présente invention concerne un procédé et un appareil pour sélectionner un intervalle. Le procédé est utilisé dans un équipement utilisateur (UE) et consiste : à recevoir des informations de configuration envoyées par une station de base, les informations de configuration étant utilisées pour indiquer une heure à laquelle un intervalle de mesure apparaît ; à déterminer si l'intervalle de mesure est ou non en conflit avec un intervalle de SL selon l'heure à laquelle l'intervalle de mesure apparaît et l'heure à laquelle l'intervalle de SL apparaît, l'heure à laquelle l'intervalle de SL apparaît étant configurée selon une politique préétablie ; lorsque l'intervalle de mesure est en conflit avec l'intervalle de SL, à sélectionner l'un de l'intervalle de mesure et de l'intervalle de SL ; lorsque l'intervalle de mesure est sélectionné, à réaliser une mesure de cellule voisine dans l'intervalle de mesure ; ou lorsque l'intervalle de SL est sélectionné, à transmettre un paquet de données dans l'intervalle de SL. La présente invention résout le problème d'importante difficulté de configuration d'intervalle et de faible efficacité de configuration lorsqu'une station de base configure, pour chaque UE, un intervalle de mesure et un intervalle de SL qui sont complètement décalés, permettant ainsi d'obtenir l'effet d'amélioration de l'efficacité de configuration d'intervalle.
