Title
(EN) SYSTEMS AND METHODS FOR CONFIGURATION OF OFFSET FACTORS AND MAINTENANCE OF CONSTANT RESELECTION RANGE IN A WIRELESS COMMUNICATION ENVIRONMENT
(FR) SYSTÈMES ET PROCÉDÉS PERMETTANT UNE CONFIGURATION DE FACTEURS DE DÉCALAGE ET LE MAINTIEN D'UNE PLAGE DE RESÉLECTION CONSTANTE DANS UN ENVIRONNEMENT DE COMMUNICATION SANS FIL
Abstract
(EN)
A method for self-configuration of offset factors between two base stations in a wireless communications system is described. A first offset factor is sent to a first user equipment (UE) by a first base station. An offset factor is an indication of the reselection area around a home evolved nodeB (HeNB). A second offset factor is received from a second UE. The first offset factor is modified using the second offset factor. The modified first offset factor is sent to the first UE.

La présente invention porte sur un procédé permettant une configuration automatique des facteurs de décalage entre deux stations de base dans un système de communication sans fil. Un premier facteur de décalage est envoyé à un premier équipement utilisateur (UE) par une première station de base. Un facteur de décalage est une indication de la zone de resélection autour d'un nœud domestique évolué (HeNB). Un second facteur de décalage est reçu d'un second UE. Le premier facteur de décalage est modifié à l'aide du second facteur de décalage. Le premier facteur de décalage modifié est envoyé au premier UE.
