アブストラクト
  Channel-state-aware scheduling strategies on wireless links play an essential role for enhancing throughput performance of elastic data traffic by exploiting channel fluctuations. Especially in HSDPA (High-Speed Downlink Packet Access), while various channel-state-aware schedulers have been proposed, each of them has pros and cons, and thus, none of them can be the best solution for all situations and policies in the base station management. To respond to the variety of the base station management, in our previous paper, a unified scheduler that can flexibly vary its characteristics by adjusting its parameters was proposed, but only the basic packet-level performance was evaluated. In this paper, therefore, the detailed performance characteristics of the proposed unified scheduler are investigated. First, it is shown that the unified scheduler meets a general fairness criterion (¥mathbf{p},¥alpha)-proportional fairness in terms of the asymptotic behavior of the long-term averaged throughput. Second, the TCP-level throughput performance of the unified scheduler with some link-layer technologies actually employed in HSDPA is evaluated by network simulation. Lastly, two scenarios to set the parameters of the scheduler the semi-proportional fair scheduling and the semi-greedy scheduling are examined, which demonstrate the flexibility and effectiveness of the unified scheduler.
