Multi-Cell Cooperation with Fairness Constraint in the Downlink OFDMA Cellular Networks
Hongxing Li, Hanwen Luo, Wen Chen, Jia Guo · IEICE Transactions on Communications · 2010
In this letter, we study cell cooperation in the downlink OFDMA cellular networks. The proposed cooperation scheme is based on fractional frequency reuse (FFR), where a cooperation group consists of three sector antennas from three adjacent cells and the subchannels of each cooperation group are allocated coordinately to users. Simulation results demonstrate the effectiveness of the proposed schemes in terms of throughput and fairness.
