Abstract
In this paper, we investigate the ergodic sum rate for multiple-input single-output(MISO) downlink multi-user systems. We assume that each user has perfect channel state information( CSI), while the base station has only statistical CSI of all users. We derive an approximation of the ergodic sum rate. Then, new scheduling and statistical beamforming space division multiple access(SDMA) transmission are derived through maximizing the approximation. The proposed algorithm are shown to perform well.
