Techniques for managing interference in a wireless network are described. A base station may receive enhanced pilot measurement reports from user equipments (UEs) and may make an interference management decision based on the received reports. The base station may select a serving base station for a UE based on an enhanced pilot measurement report received from the UE. The base station may determine resources with a low target interference level at a neighbor base station and may avoid scheduling a UE for uplink transmission on the resources. The base station may also determine whether to reserve resources for a neighbor base station based on data performance of the neighbor base station, whether the neighbor base station observes high interference from UEs served by the base station, or whether UEs served by the neighbor base station observe high interference from the base station, which may be determined based on the enhanced pilot measurement reports.

L'invention concerne des techniques de gestion dinterférence dans un réseau sans fil. Une station de base peut recevoir des rapports de mesure pilotes améliorés déquipements dutilisateur (UE) et peut prendre une décision de gestion dinterférence en fonction des rapports reçus. La station de base peut choisir une station de base de desserte pour une UE en fonction dun rapport de mesure pilote amélioré reçu de lUE. La station de base peut déterminer des ressources avec un faible niveau dinterférence cible sur une station de base voisine et peut éviter la planification dune UE pour une transmission sol-air sur les ressources. La station de base peut également déterminer sil faut mettre en réserve des ressources pour une station de base voisine en fonction de la performance des données de la station de base voisine, si la station de base voisine observe une interférence importante à partir des UE desservies par la station de base station, ou si les UE desservies par la station de base voisine observent une interférence importante à partir de la station de base, ce qui peut être déterminé en fonction des rapports de mesure pilotes améliorés.
