ABSTRACT:
The present invention relates to a method for reducing inter-cell interference in a cellular radio system in which said scheduler controls a set of shared radio resources. The method comprises the steps of—assigning cell specific resource priority weights (RPW) to the different radio resources of a cell, said assignment differs from the assignment of the same radio resources in at least one neighboring cell utilizing the resource priority weights for selection of radio resources. The resource priority weights can furthermore be combined with channel quality indication reports (CQI) to form weighted quality indexes (WCQI) for the radio resources that are available to the scheduler. The invention also relates to a scheduler performing said method and a radio network node comprising such scheduler.
