Title (EN) METHODS AND APPARATUS FOR INTERFERENCE MANAGEMENT
(FR) PROCÉDÉS ET APPAREIL DE GESTION D'INTERFÉRENCES
Abstract:
(EN) Systems and techniques for managing interference between pico cells in a pico cluster. Pico eNodeBs are configured in groups for each of a plurality of UEs, based on factors such as signal to noise ratio and geographic location. All signals from UEs may be measured by all eNodeBs in the cluster, but a pico group decodes packets only of UEs associated with the pico group. Decoded packets are exchanged between pico groups, and when a pico group is unable to decode packets of an associated UE, is uses the decoded packets received in exchanges to reconstruct an interference signal. The interference signal is subtracted from the received signal and the resulting received signal is used to decode the packets of the UE.
(FR) L'invention concerne des systèmes et des techniques pour gérer des interférences entre des pico-cellules dans un pico-amas. Des pico eNodeB sont configurés en groupes pour chacun de plusieurs EU en fonction de facteurs comme le rapport signal-bruit et l'emplacement géographique. Tous les signaux des EU peuvent être mesurés par tous les eNodeB de l'amas, mais un pico-groupe décode des paquets uniquement pour les EU associés au pico-groupe. Les paquets décodés sont échangés entre les pico-groupes, et lorsqu'un pico-groupe est incapable de décoder des paquets d'un EU associé, il utilise les paquets décodés reçus lors des échanges afin de reconstruire un signal d'interférence. Le signal d'interférence est soustrait du signal reçu, et le signal reçu résultant est utilisé pour décoder les paquets de l'EU.
