A New Tractable Model to Estimate the Uplink Inter-Cell Interference in LTE

Abstract

This paper presents a tractable model to estimate the uplink Inter-Cell Interference (ICI) in fully loaded LTE networks. Interfering users are considered to be uniformly distributed in an annulus so that evaluation of the interference power is obtained asymptotically for a high number of users. Model validity is proved through Monte Carlo simulations, showing that analytical results are close to simulation results even for a low number of users per cell.
