Uplink Interference Co-ordination/Avoidance in LTE Systems
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.
