We present a statistical approach for estimating the interference coupling coefficients in an LTE network based on a set of various measurements available at the network and terminal level. The proposed approach combines the measurements with prior information (spatial correlation among interference links) and takes into account measurement uncertainty. The result is a simple closed-form estimator that allows for fast realtime interference estimation.
