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