Abstract

Multiuser diversity is an effective technique to increase the capacity of wireless networks. However, the poor fairness among the mobile stations (MSs) and the heavy feedback load as the number of MSs increases are the main problems in implementing multiuser diversity. We propose a new scheduling scheme with opportunistic feedback. Specifically, the schedule for multiple users is based on two different criteria such as the absolute SNR and the normalized SNR. Simulation result shows that the tradeoff between capacity and fairness can be fine-tuned through the proposed scheduling scheme. © 2009 IEEE.
