摘要：
A method and a radio base station are provided for selecting a first User Equipment (UE) and at least a second UE from a plurality of UEs, for sharing a transmission resource in the time-frequency dimension in a multiple input multiple output (MIMO) transmission. A first and second imperfection of Channel State Information (CSI) made available for the first UE and second UE, respectively is estimated (410, 420). Spatial correlation between the first UE and the at least second UE is estimated (450), and the first and at least second UE are selected (470) to share a transmission resource in the time-frequency dimension, if both of the first and second imperfections are determined above (430, 440) a first threshold and the spatial correlation is determined below (460) a second threshold.
