Abstract
Systems and methods are described for detecting interference at an access node. A rate at which packets are unsuccessful received at a wireless device may be monitored, wherein the wireless device is in communication with a cell of an access node. The access node may retransmit one or more unsuccessfully received packets to the wireless device. A retransmission metric for retransmission attempts to the wireless device from the access node may be monitored. And it may be determined that communication between the cell of the access node and the wireless device is experiencing interference from a neighboring cell when the monitored rate and monitored retransmission metric meet the interference criteria.
