Multiple Input Multiple Output (MIMO) antenna systems are being used to increase the spectral efficiency for the next generation of wireless networks (LTE, WiMAX). In this paper the authors focus on beamforming techniques for the downlink channel. In particular, the authors consider the problem of downlink user selection to maximize the downlink resources while satisfying the QoS requirements of all users. They do this by assigning suitable utility functions to user flows that are designed to maintain the specified QoS constraints.
