Abstract

In this paper, a simple and practical multiuser scheduling based on switched diversity with adaptive modulation is presented. This switch-based multiuser scheduling scheme results in an average feedback load that is lower than using the optimal opportunistic multiuser scheduling scheme while offering the optimum overall system spectral efficiency when used with the highest threshold in the adaptive modulation. Numerical results show we can obtain a trade-off between spectral efficiency and the feedback load by choosing the user switching threshold appropriately. In addition, system operation can be adaptively altered based on the optimization goal and the given resource budget by a user switching threshold change.
