Abstract

The present disclosure relates to a link adaptation scheme. In one embodiment there provides a method for performing link adaptation in an uplink subframe for a first cell the method comprising: obtaining interference to the uplink subframe of the first cell from at least one neighboring cell s downlink subframe occupying a time interval same as the uplink subframe; determining whether the obtained interference exceeds a predetermined threshold; and applying to the uplink subframe a first link adaptation loop when the obtained interference exceeds the predetermined threshold.
