Femto cell system is promising to provide costeffective
strategy for high data traffic and high spectral efficient services
in future wireless cellular system environment. However, the cochannel
operation with current Macro networks occurs some
severe interference between Macro and Femto cells. Hence, the
interference cancellation or management schemes are imperative
between Macro and Femto cells in order to avoid the decrease of
total cell throughput. First, we briefly investigate the
conventional resource allocation and interference cancellation
scheme between Macro and Femto cells. Then, we propose an
adaptive resource allocation scheme based on the distribution of
Femtocell traffic in order to increase the cell throughput and also
maximize the spectral efficiency over the FFR (Fractional
Frequency Reuse) based conventional resource allocation
schemes. Simulation results show that the proposed scheme
attains a bit similar SINR (Signal to Interference Noise Ratio)
distribution but achieves much higher total cell throughput
