There is provided a radio system, having a receiver for receiving cell
measurement data with respect to an own cell and adjacent cells of each
user terminal of a plurality of cells of the radio system; a calculation
unit for comparing resulting interference values of different user
terminal combinations within the same frequency-time resource group of
the radio system on the basis of the cell measurement data, the
frequency-time resource group including user terminals of more than one
cell; and a processing unit for controlling resource allocation in at
least part of the frequency-time resource groups on the basis of the
comparison.
