Abstract—In this paper, an Inter-Cell Interference Coordination (ICIC) scheme is proposed for the uplink transmission in Long Term Evolution (LTE) systems. Firstly, an efficient ICIC scheme which combined a semi-static resource allocation plan is presented. Secondly, applied by High Interference Indicator (HII), a Physical Resource Block (PRB) reuse avoidance algorithm is proposed to reduce multi-cell co-channel interference. Thirdly, a power control method is applied based on the Overload Indicator (OI), by setting transmit power of cell-center users. Simulation results show that the proposed algorithm improves the cell-edge throughput and increases total throughout performance effectively.
Index Terms—inter-cell interference coordination, soft frequency reuse, semi-static
