Abstract

The main source of interference in OFDMA system in downlink is inter-cell interference, which can severely limit the throughput of users near the cell edge. The inter-cell interference coordination (ICIC) is one method to improve the performance. In this paper autonomous inter-cell interference avoidance schemes under fractional load (FL) conditions in the downlink for 3rd generation partnership project (3GPP) long term evolution (LTE) are proposed. The proposed schemes do not require any inter-cell signaling for ICIC; rather the decision about the allocation of the spectrum in order to avoid the inter- cell interference is taken based on the information available within the cell itself. We show that the schemes for spectral resource selection is important for FL scenario to avoid high BLER. The proposed schemes further improve the SINR condition therefore higher cell throughput and coverage are realized.
