To eliminate interference from picoevolved Node Bused in closed subscriber group control, a dynamicload-aware-based enhanced inter-cell interference coordination (eICIC) scheme was proposed. First, the scheme is used to estimate changes in network load by forecasting the Markov chain. As a result, the incorrect configuration of almost-blank subframes (ABS) caused by time latency in the, LTE system can be avoided. Such incorrect configuration reduces system capacity. Second, the scheme is used to dynamically reconfigure ABS based on the forecasted Markov chain. An optimized system model based on dynamic reconfiguration of ABS was proposed to maximize system throughput. Simulation demonstrates that the proposed scheme did increase overall system throughput significantly compared with traditional eICIC schemes.
