| Abstract(in English) | This paper presents uplink spatial scheduling with adaptive transmit beamforming, where terminals perform system-based transmit beamforming in multiuser multi-input multi-output (MIMO) systems. In the presented spatial scheduling, the base station (BS) selects appropriate combination of terminals and their transmit beamforming among possible terminals. In the selection process, a terminal and its transmit beamforming for a signal are successively determined, considering the effect of the other predetermined signals, under all possible transmit beamforming. In performance evaluation, we show that the spatial scheduling achieves much larger system throughput than the system that terminals send a fixed number of signals. We also present basic system configuration that the BS reports the target transmit beamforming to the selected terminal on downlink. |
