How Much Multiuser Diversity is Required for Energy Limited Multiuser Systems?

We answer the fundamental question of how much multiuser diversity is required for energy limited multiuser multiple-input multiple-output systems. This research is the first to apply power balance between multiuser scheduling and data transmission. Results prove that achievable multiuser diversity gain can be improved by activating only a subset of users. This yields a greener multiuser scenario showing potential for balancing resources between multiuser scheduling and data transmission in energy-limited systems. These results contributed to a subsequent (2008) Canadian Natural Science and Engineering Research Council project, "Intelligent Signal Processing for Ubiquitous, High-Capacity, Heterogeneous, Scalable Wireless Networks".
