In this paper, the authors address the problem of the impact of relays on the performance of a LTE-A based network. In this aim, they propose a new framework, the \"Fluid model for LTE-A networks with relays\". They derive from this model analytical simple formulas for the Signal to Interference plus Noise Ratio (SINR), taking into account inter-cell interference, which allow to study performance of wireless networks constituted by macro base stations and relays. In their analysis, a fraction of radio resources is dedicated to the base-station (eNode-B)/Relay Nodes (RN) communication.
