Framework for Fair Scheduling Schemes in the Next Generation High-Speed Wireless Links

A very significant evolution of mobile telecommunication technologies is the introduction of the high-speed downlink shared channel used by many users to efficiently accommodate packets in networks. In a wireless environment, because of the time-varying channel fluctuations of wireless links, efficient use of the large available bandwidth cannot be achieved without adopting sophisticated channel-stateaware packet scheduling strategies. To cope with this issue, many downlink packet schedulers have been developed and investigated to achieve high throughput and fair share of the link bandwidth. However, handling all situations by simply applying specific schemes is impossible, and, therefore, more than one scheduler may have to be implemented and selectively employed in a base station. Thus, in this paper, we propose a novel framework for downlink packet schedulers to integrate these existing schedulers into a unified form, and evaluate the basic performance by carrying out simulations.
