Transmission scheduling for efficient wireless resource utilization with minimum-performance guarantees

Xin Liu, Edwin K. P. Chong, Ness B. Shroff

Abstract: We present an "opportunistic" transmission scheduling scheme that exploits time-varying channel conditions and maximizes the average system performance under minimum-performance guarantees. We establish the optimality of the scheduling scheme, and show that the proposed opportunistic scheduling scheme can provide a "no-loss" guarantee compared to non-opportunistic scheduling policies. Furthermore, we show that the feasibility region of users' requirements is convex, and discuss the associated admission control issues. Last, through simulation results, we show that the scheme results in significant performance improvement.
