Partial feedback multi-user scheduling in multi-antenna systems

In this paper we consider the greedy scheduling algorithm that routes transmission of users' packets based on their reported CSI in the uplink channel to the user with the best instantaneous channel conditions. We propose a scheduling scheme that relies on reporting partial feedback of the CSI. We compare the proposed scheme to the one that uses perfect channel information at the base station, we will see that the proposed scheme has significantly less complexity at the expense of a loss in the system's capacity.
