Abstract

In this paper, we consider the effect of multiplexing users in a frame (more specifically, coherent time) on providing quality of service (QoS) in multiuser wireless networks. For this purpose, we propose simple and efficient scheduling schemes that can yield substantial capacity gain. Our approach involves maximizing the throughput subject to a given delay QoS constraint by choosing the appropriate number of users to be served in a frame. We call this number the degree of multiplexing. We investigate the effect of the degree of multiplexing on QoS performance in wireless multiuser scheduling by analyzing the effective capacity and then develop an approach to finding the optimal degree of multiplexing by asymptotic approximation.
