Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: ,  investigate an application of two different beamforming techniques and propose a novel downlink por minimization scheme for a two-tier heterogeneous network (HetNet) model. In this context,  employ the time reversal (TR) technique to a femtocell base station, whereby  assume that a macrocell base station uses a zero-forcing-based algorithm, and the communication channels are subject to frequency selective fading. Additionally, the HetNet backhaul connection is unable to support a sufficient throughput for signaling an information exchange beten two tiers. Given the considered HetNet model, a downlink por minimization scheme is proposed, and closed-form expressions concerning the optimal solution are provided by taking this constraint into account. Furthermore, considering imperfect channel estimation at TR-employed femtocell, a worst-case robust por minimization problem is formulated. By devising TR worst-case analysis, this robust problem is transformed into an equivalent formulation that is tractable to solve. The results presented in our paper, show that the TR technique outperforms the zero-forcing one from the perspective of beamforming methods for femtocell working environments. Finally,  validate the proposed por loading strategy for both cases of perfect and imperfect channel estimations.
