摘要： A method (310) of power control for multi-user multi-input multi-output (MU-MIMO) transmissions between a pair of mobile terminals and a radio base station is provided. The method comprises determining (312) signal-to-interference-noise ratios (SINRs) for the radio channels between the mobile terminals and the radio base station, determining (312) a channel orthogonality between the radio channels, and jointly determining (315), based on the SINRs and the channel orthogonality, power adjustment values for the mobile terminals. The present invention makes use of an understanding that the system gain resulting from MU-MIMO transmissions may be improved by optimizing the transmission power of the co-scheduled mobile terminals. For instance, the power adjustment values may be determined so as to attain certain SINR targets. Alternatively, the power adjustment values may be determined so as to maximize the throughput while maintaining a power budget constraint. Further, a radio base station for MU-MIMO transmissions is provided.
