Title
(EN) HANDOVER CRITERIA FOR WIRELESS NETWORKS
(FR) CRITÈRES DE TRANSFERT INTERCELLULAIRE DE RÉSEAUX SANS FIL
Abstract
(EN)
Handover criteria for wireless networks are provided. A base station (BS) transmits, to a user equipment (UE), a configuration for at least one measurement event to be used for a handover of the UE from a source cell to one of a set of neighbor cells, wherein the configuration includes at least a configured rank criterion for triggering a measurement report in response to the measurement event. The BS receives, from the UE, the measurement report based on the configuration, the measurement report at least including a measured rank value for one or more reported cells in the set. The BS selects a target cell from the reported cells for the handover based at least on the received measured rank values, and transmits a handover command to the UE for the handover to the selected target

L'invention concerne des critères de transfert intercellulaire de réseaux sans fil. Une station de base (BS) transmet à un équipement utilisateur (UE) une configuration d'au moins un événement de mesure à utiliser pour un transfert intercellulaire de l'UE depuis une cellule source vers une cellule d'un ensemble de cellules voisines, la configuration comprenant au moins un critère de rang configuré permettant de déclencher un rapport de mesure en réponse à l'événement de mesure. La BS reçoit en provenance de l'UE le rapport de mesure en fonction de la configuration, le rapport de mesure comprenant au moins une valeur de rang mesurée pour une ou plusieurs cellules rapportées dans l'ensemble. La BS sélectionne une cellule cible parmi les cellules rapportées pour le transfert intercellulaire au moins en fonction des valeurs de rang mesurées reçues, et transmet une commande de transfert intercellulaire à l'UE pour le transfert intercellulaire vers la cible sélectionnée.
