The disclosure relates to a method performed by a network node, comprising acquiring cell capacity information of a plurality of cells corresponding to a Distributed Unit (DU) of a base station. The method comprises determining cell capacity summations corresponding to the DU based on each cell corresponding to different cell capacities, based on the cell capacity information. The method comprises determining a predicted cell capacity of the plurality of cells based on the cell capacity summations, for the base station allocating a cell capacity with respect to each of the plurality of cells according to the predicted cell capacity.
