The Reduced Power Subframes (RPS) are encouraged to be applied in the LTE-Advanced Heterogeneous Networks (HetNets), to reduce the capacity loss caused by the Almost Blank Subframes (ABS). However, the RPS are supposed to be used in the macrocells only. In fact, the RPS can also be used in femtocells to mitigate the interference that the macrocell edge users suffers, but its performance is not investigated yet. In this paper, we introduce the RPS both in the macrocells and the femtocells. The results of the Signal to Interference Ratio (SIR) coverage probability under the stochastic geometry framework are derived in a closed-form which is verified through Monte Carlo simulation. Based on these results, the macrocell edge users' SIR coverage and the average rate coverage of the network (the average fraction of users achieving a target rate) are analysed numerically. Our proposed scheme enhanced both the SIR of the macro edge users and the average rate coverage probabilities.
