Abstract
Methods and systems are provided for reducing interference across coverage cells using base stations interconnected by a packet network. A wireless device monitors the channel signal strength of its serving cell and its neighboring cell. The serving cell collects measurements from the wireless devices within its cell and informs its neighboring cell when one of the wireless device may be causing significant interference to the neighboring cell. The neighboring cell collects this information and executes a multi-user detection and cancellation algorithm on a subset of these interfering wireless devices.
