抄録(英) | Multiuser diversity is a fundamental characteristic of multiuser fading channels, and can be exploited to improve the system performance by opportunistically scheduling users on favorable resources. However, focusing only on the possible diversity gain can lead to unfair treatment of individual users. The main important characteristic of an adaptive and efficient scheduling scheme is to maximize throughput while providing fair services to the user, especially under strict quality of service requirements for all users. To achieve this goal, we consider the problem of multiuser scheduling under a given fairness constraint. A novel Adaptive Fairness and Throughput Control (AFTC) approach is proposed to maximize the network throughput while attaining a given fairness degree. Simulation results reveal that the long-term average fairness achieved by applying the proposed AFTC approach, is equal to the desired fairness and is stable in different operating conditions. The trade-off between fairness and throughput is accurately controlled by adjusting the scheduler's parameters. |
