Energy-performance trade-offs in multiuser scheduling: large system analysis

This work addresses the problem of data scheduling over fading channels in a deadline (strict delay) constrained multiuser system where a certain amount of data loss can be tolerated. We propose a scheme which schedules the users based on their instantaneous channel conditions and backlog of the packets stored in the buffer. The scheme is analyzed in large user limit. Numerical results demonstrate the energy-performance trade-offs and quantify the gain in energy efficiency for the proposed scheme
