Abstract
LTE networks’ main challenge is to efficiently use the available spectrum and to provide satisfying quality of service for mobile users However using the same bandwidth among adjacent cells leads to occurrence of Intercell Interference especially at the celledge Basic interference mitigation approaches consider bandwidth partitioning techniques between adjacent cells such as frequency reuse of factor m schemes to minimize celledge interference Although SINR values are improved such techniques lead to significant reduction in the maximum achievable data rate Several improvements have been proposed to enhance the performance of frequency reuse schemes where restrictions are made on resource blocks usage power allocation or both Nevertheless bandwidth partitioning methods still affect the maximum achievable throughput In this proposal we intend to perform a comprehensive survey on InterCell Interference Coordination ICIC techniques and we study their performance while putting into consideration various design parameters This study is implemented throughout intensive system level simulations under several parameters such as different network loads radio conditions and user distributions Simulation results show the advantages and the limitations of each technique compared to frequency reuse1 model Thus we are able to identify the most suitable ICIC technique for each network scenario
