Nowadays cellular systems operate with frequency reuse one, where adjacent cells use the same frequency band. Use Equipments (UEs) located at cell edge are mostly affected by the resulting co-channel interference. In addition, cell edge UEs suffer from their weak carrier signal strength. This paper proposes a new method to increase the performance of cell edge UEs by means of information exchange between Base Stations (BSs). A BS serving a cell edge UE requests support from a co-channel BS. The supporting BS transfers demodulated or decoded bits received from the cell edge UE back to the serving BS. The serving BS then combines the information.
