Abstract
In multicell OFDMA systems, throughput is severely degraded by other cell interference (OCI), especially at cell edge. To satisfy the performance requirement, OCI must be mitigated effectively. Several schemes have been proposed to handle this problem by coordinating the way to allocate spectrum resource to each cell. Since the allocation of spectrum has effects on OCI mitigation and the spectral efficiency, an wise strategy to consider those two factors is required. In this paper, we propose a new scheme named as power division reuse partitioning scheme (PDRPS). PDRPS balances OCI mitigation and spectral efficiency by adopting interference cancelation (IC) scheme. The simulation results show that PDRPS has more throughput and lower outage probability than the conventional schemes.
