Providing for virtual management of wireless re-sources in a mobile communication environment is described herein. By way of example, access terminals in the communica-tion environment can maintain connections with nearby net-work transmitters and report factors pertinent to wireless scheduling to a central entity, such as a macro base station. The macro base station can employ those factors in improving wire-less communications for other serving cells within or near to a macro coverage area served by the macro base station. By main-taining information pertinent to prevailing wireless conditions, quality of service requirements, pilot signal reports, mobility management considerations, and so on, of transmissions within the cell, significant interference reduction can be implemented for the macro coverage area, or nearby coverage areas.

La présente invention concerne la gestion virtuelle de ressources réseau dans un environnement de communication mobile. Par exemple, des terminaux d'accès présents dans l'environnement de communication peuvent actualiser des connexions avec des émetteurs réseau proches et envoyer des rapports concernant des facteurs pertinents pour l'ordonnancement sans fil à une entité centrale, telle qu'une macro station de base. La macro station de base peut utiliser ces facteurs pour améliorer les communications sans fil pour d'autres cellules de desserte qui se trouvent dans une macro zone de desserte desservie par la macro station de base ou à proximité d'une telle zone. L'actualisation des informations pertinentes aux conditions sans fil dominantes, aux exigences de qualité de service, aux rapports de signal pilote, aux considérations de gestion de la mobilité, et autres, des transmissions s'effectuant dans la cellule, permet de réduire sensiblement les interférences pour la macro zone de desserte ou les zones de desserte proches.
