SOFT SPATIAL-FREQUENCY REUSE BASED ON MINIMUM INTERFERENCE LEAKAGE

摘要：

Coordinated Scheduling/Beamforming is proposed as an attractive technology to enhance the cell edge performance. However, the performance gain comes at the cost of explicit exchange of Channel State Information (CSI) and scheduling/ precoding information over the backhaul links. In this paper, a decentralized scheme named as soft spatial-frequency reuse scheme is proposed. Different from centralized schemes, which mitigate interference from other cells, SSFR minimizes the interference leakage to adjacent cells. Compared with the traditional interference coordination scheme, the SSFR could improve the cell-edge throughput by 30％, and total cell throughput by 2~10％.
