There are many capacity enhancement techniques in wireless networks. Multiple-input-multiple-output (MIMO) antenna systems, channel-state based packet data scheduling algorithms and adaptive modulation and coding are examples of such techniques. In this paper, we provide the simulation results for various transmission schemes (including MIMO) in conjunction with a channel-state-based scheduling algorithm and an adaptive modulation and coding scheme Consequently, we demonstrate the cellular system capacity gain resulting from interaction between these three techniques. Specifically, system-level simulations are presented for the wideband CDMA (WCDMA) downlink shared channel.
