N2 - In this paper we investigate performance of frequency <br/>domain packet scheduling (FDPS) under fractional load <br/>(FL), based on the UTRAN Long Term Evolution downlink. <br/>FL may be regarded as an inter-cell interference (ICI) mitigation <br/>technique, which can improve the user experienced <br/>SINR. We consider FL based on transmission using a subset <br/>of the time-frequency resources, in an un-coordinated manner <br/>throughout the cellular network. On the basis of detailed system-level <br/>simulations we find that FDPS under FL can provide a <br/>performance trade-off between improvement in coverage and the <br/>loss in cell throughput. For example, at FL of 25% the coverage <br/>is improved by a factor of two, while the average cell throughput <br/>is halved, compared to the full load case. Further, it is shown <br/>that FDPS performance is sensitive to the rate at which state <br/>transition of the time-frequency resources takes place as link <br/>adaptation is not able to track fast variations in the SINR.
