Throughput of cooperative MIMO communications with FFR

Cooperative MIMO is a key technology for next generation mobile communications. This technique is used to improve cell edge throughput performance. In this paper, we propose a cooperative MIMO scheme with FFR, and evaluate downlink performance of the scheme. We use 3 sector structures per cell. The sector cell is divided into two regions, inner cell and outer cell. The frequency reuse factor (FRF) is 1 in the inner cell and 3 in the outer cell. The cooperative MIMO scheme is employed in the outer cell while a single base station serves in the inner cell. We compare two types of model and give those performances. The system performances are measured by the user throughput and the sector throughput. Simulation results show that the cooperative MIMO scheme could provide higher user throughput in the cell edge.
