Abstract :
In this paper, we propose and evaluate a new interference co-ordination scheme for the uplink of LTE systems. This presented approach mitigates the effects of ICI (Inter-Cell Interference) by finding suboptimal frequency and power assignments to all users in a given cellular network. The spectral efficiency of cell-edge users is enhanced in this scheme and simulation results show that our presented approach outperforms Samsung´s Flexible Fractional Frequency Reuse (FFFR) algorithm which is one of the interference coordination schemes proposed for LTE systems.
