M. Tech. Electrical Engineering / It is widely believed that the implementation of multi-user multiple-input multiple- output (MU-MIMO) technology at the radio access portion of current and future wireless networks would positively impact on the performance of such networks. This however demands the design of efficient multi-user scheduling algorithms at the data link layer. One algorithm that is known to be throughput optimal is the opportunistic scheduler. This work takes a cross-layer approach in designing a scheduler that takes into account both the channel and queue states of users. We propose a scheduling algorithm referred to as the Maximum Throughput Scheduler (MTS). The MTS explicitly expresses network throughput as the utility function. Through simulations, we show that the MTS outperforms other schedulers in terms of network throughput.
