Centralized Proportional Fair (PF) Scheduling with Concurrent Transmission Enabled in Wireless Multi-Hop OFDMA Networks

The paper proposes the scheduling method to not only implement the proportional fairness between terminal users but also improve spectral efficiency by enabling concurrent transmission (CT) in wireless multi-hop OFDMA networks. The overhead reduction of channel quality information (CQI) is presented in coupling with the proposed scheduling and hereafter its performance with the reduced CQI is discussed. Simulation results illustrate the proposed scheme outperforms the prior art on both spectral efficiency and fairness.
