Title (EN) METHOD AND APPARATUS FOR INTERFERENCE MITIGATION USING MOBILE STATION SIGNALING
(FR) PROCÉDÉ ET APPAREIL PERMETTANT UNE RÉDUCTION DES INTERFÉRENCES À L'AIDE D'UNE SIGNALISATION DE STATION MOBILE
Abstract:
(EN) A Mobile Station (MS) and a Closed Subscriber Group (CSG) Femtocell Base Station (FBS) for Interference Mitigation (IM) in a wireless communication system, and methods for their operation, are provided. A method for operating the MS includes determining if the MS cannot access a first CSG FBS due to interference from a second CSG FBS, the first CSG FBS being a CSG FBS that the MS is authorized to receive service from and the second CSG FBS being a CSG FBS that the MS is not authorized to receive service from, and if it is determined that the MS cannot access the first CSG FBS due to interference received from the second CSG FBS, transmitting an IM-Signal to the second CSG FBS requesting that the second CSG FBS mitigate the interference to the MS.
(FR) La présente invention porte sur une station mobile (MS) et sur une station de base pour femtocellules (FBS) de groupes d'abonnés fermés (CSG) permettant une réduction des interférences (IM) dans un système de communication sans fil et sur leurs procédés de fonctionnement. Un procédé de fonctionnement de la MS consiste à déterminer si la MS ne peut avoir accès à une première station FBS de groupes CSG à cause d'une interférence provenant d'une seconde station FBS de groupes CSG, la première station FBS de groupes CSG étant une station FBS de groupes CSG de laquelle la MS peut recevoir un service et la seconde station FBS de groupes CSG étant une station FBS de groupes CSG de laquelle la MS ne peut pas recevoir de service et, s'il est déterminé que la MS ne peut pas avoir accès à la première station FBS de groupes CSG à cause d'une interférence reçue de la seconde station FBS de groupes CSG, transmettre un signal IM à la seconde station FBS de groupes CSG demandant que la seconde station FBS de groupes CSG réduise l'interférence au niveau de la MS.
