摘要：

Using femtocell in LTE with small coverage area is considered have more effective performance than Macro BTS ( eNB). However, using femtocells ( HeNB) in LTE will make interference problem among femtocell ( HeNB) to the Macro BTS ( eNB). Femtocell is a source of interference for users who cannot access it. Therefore it is necessary for interference coordination methods among the HeNB and eNB. The methods are ICIC ( Intercell Interference Coordination) and eICIC ( enhanched Intercell Interference Coordination). ICIC method is using frequency resource allocation that allocating every user in different subcarrier. eICIC method is allocating almost blank subframe ( ABS) in time domain resource for macro user that got interference from femtocell ( HeNB). Simulation result in frequency resource allocation using ICIC method can increase SINR 43.04 % and throughput 23.09 %. However using eICIC method in time domain resource can increase performance of SINR 54.32 % and throughput 74.78 % that is better than frequency resource allocation.
