Understanding Static Intercell Interference Coordination Mechanisms in LTE

Ashley Mills, David Lister, Marina De Vos

Abstract


This work identifies the factors which determine the behaviour of static interference avoidance schemes: SINR distribution shift, MCS mapping, and proportional MCS usage. The work goes on to challenge the common assumption that it is ``best'' to give resources with a high reuse factor to those at the cell-edge, by showing for a fixed rate service class, that it is best to be greedy and give these resources to those at the cell-centre. The work is performed using monte-carlo simulations, only in the downlink direction, on a London scenario with realistic path loss and network data. All work is statistically quantified using appropriate tests.
