Abstract:
Methods and apparatuses are provided for determining whether to handover a device to mitigate uplink interference while achieving acceptable uplink service quality in a wireless network. One or more parameters related to a device can be evaluated to determine whether to handover the device, such as a number of transmission power reports received from the device over a period of time, a frame error rate, setpoint, or power control commands related to the uplink of the device, a received pilot signal strength at the device, an uplink throughput or buffer size at the device, etc., from which transmit power information of the device can be inferred for determining whether the device potentially interferes with access points or devices. Based on the one or more parameters, an access point can determine whether handing over the device may mitigate such uplink interference while ensuring uplink service quality, and accordingly handover the device.
