Abstract :
Future wireless communication systems like 3GPP Long Term Evolution are required to support extreme high speed packet data transmission. Due to the limitation of available spectrum resource, high spectrum efficiency technologies are needed to be explored for different OSI layers. Over last decades, many technologies have been investigated to achieve this target. Multiple-input multiple-output (MIMO) system and channel-aware scheduling are two promising schemes proposed for that achievement. In this paper, we investigate the impact of MIMO and scheduling in the increasing of the system throughput of next generation mobile wireless systems when transmitting on different channels for several transmission modes. A cross-layer approach in resource allocation and scheduling schemes is emphasized.
