Comparison of frequency reuseschemes for LTE micro-macro cells

LTE networks offer high capacity and high performance. Frequency Reuse schemes used in LTE network planning are optimized using inter-cell interference. Macro cells were install for large coverage area, but channel capacity is limited. Micro/macro technique used for increase capacity in the need high traffic area. The limiting factor the influences LTE performance is the interference from neighboring cells. This paper proposes FFR (Fraction Frequency Reuse) for micro/macro cells with sectoring. Micro/macro cells coordinated model is investigated. Simulation results to compare the capacity of micro/macro cell model cause of different number of carriers.
