摘要： For allowing a high level of performance quality within a network while reducing computational method complexity a method for operating a wireless network is claimed, wherein at least one MIMO (Multiple Input Multiple Output) group of different stations will be constructed by means of a grouping algorithm based on a grouping metric for providing a MIMO group of different stations which can be addressed simultaneously in space by a base station using MIMO techniques and meeting a definable level of performance quality and wherein the grouping metric is based on an SINR (Signal-to-lnterference and Noise Ratio) experienced by each station within the MIMO group. The method is characterized by the following steps: computing an SNR (Signal-to-Noise Ratio) that a new station would experience without any interference when added to an already existing MIMO group; computing an SINR estimate by correcting the SNR with the sum of the spatial correlations between the new station and each of the stations already present in the existing MIMO group; and using the SINR estimate for deciding whether the new station can be added to the existing MIMO group meeting the level of performance quality. Further an according network and device is claimed, preferably for carrying out the above mentioned method.
