Resource allocation and Scheduling in multiuser networks

Abstract

In this article, we address the problem of adapting power among users and their packet retransmissions in a downlink OFDMA context for optimizing a weighted sum throughput. Retransmission protocols are modeled using information-theoretic considerations. We propose a Constrained Markov Decision Process approach to optimize the weighted sum throughput subject to an average power constraint. Finally, we introduce structured policies to reduce the complexity of solving the CMDP.
