Abstract
The present invention relates to a method in a base station () and a base station () for predicting a frequency dependent Channel State Information, CSI for scheduling and link adaptation of resource blocks of an operating bandwidth, based on frequency band CSI information related to at least one UE, the method comprising the steps receiving a wideband CSI related to UE (step), receiving a UE-selected subband CSI for a bandwidth part (step), calculating the difference: the UE-selected subband CSI for the bandwidth part minus a non UE-selected SB CSI the wideband CSI (steps), and updating a non UE-selected SB CSI for at least the bandwidth part, based on the calculated difference (steps). A faster more reliable prediction method based on UE-selected SB CSI values, is hereby achieved.
