Deploying femtocells that have low power level in LTE with small coverage area is an alternative solution for mobile operators to improve indoors network coverage area as well as system capacity. However deploying femtocells (HeNB) that were used co-channel frequency, can be brought about interference problem to the Macro BTS (eNB). Close Subscriber Group (CSG) of HeNB allows only User equipment (UE) to access HeNB. HeNB is the source of interference for UE 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 (enhanced Intercell Interference Coordination). This paper proposed performance analysis of scheduling schemes for Femto to macro interference coordination that allocated resource in the frequency and time domain using LTE-Femtocell suburban and urban deployment scenario. Simulation result using ICIC methods can improve SINR performance 15.77 % in urban and 28.66 % in suburban, throughput performance 10.11 % in urban and 21.05 % in suburban. eICIC methods can improve SINR performance 17.44 % in urban and 31.14 % in suburban, throughput performance 19.83% in urban and 44.39 % in suburban.The result prove using eICIC method in time domain resource have better performance than using ICIC method in frequency resource. However using eICIC method in suburban deployment scenariocan increase the performance of SINR and throughput more effective than using eICIC method in urban deployment scenario.

This paper proposes a distributed and coordinated resource allocation algorithm in multi-cell MIMO-OFDMA systems. Firstly, each cell classifies mobile users into celledge and cell-center users based on a dynamic threshold aiming to avoid throughput loss. Secondly, each cell independently and dynamically allocates physical resource blocks (PRBs) to its cell-center users using a recursive resource allocation algorithm where the effective SINR metric is investigated. After that, each cell aggregates the unused subcarriers by its cell-center users to construct virtual PRBs. These latter are intended to be allocated to cell-edge users. Here, each cell informs its neighboring cells, via messages exchange, about its unused sub-carriers and their corresponding SINRs. If two or more cells share the same unused sub-carrier, a new collision avoidance algorithm is applied to avoid the inter-cell interference. Then, each cell constructs its virtual PRBs based on radio resource exchange between eNodeBs. After virtual PRB allocation, a power allocation procedure is performed and an adaptive modulation and coding algorithm is executed. Simulation results demonstrate that the proposed scheme permits to enhance the system performance in cell-edge and cell-center region compared to well-known algorithms.
