On re-use partitioning in LTE-FDD systems

Interference coordination schemes are essential for OFDM based systems such as LTE where the implementation of tighter frequency allocationre-use gives rise to high intercell interference, resulting in reduced coverage and low cell-edge throughputs. Re-use partitioning is one of the most attractive schemes among the plethora of interference co-ordination and avoidance methods. In this paper, we present the network level performance comparison of this scheme with the traditional re-use 1 and 3 schemes for the LTE-FDD systems. The results show that re-use partitioning benefits from the strengths of both re-use 1 around the cell-center and re-use 3 for the cell-edge users, thereby providing excellent coverage and throughput gains.
