Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  consider a system where a licensed radio spectrum is shared by two networks, namely the primary network and the secondary network. The spectrum is licensed to the primary network, hover the secondary network makes opportunistic access of the unused and/or underutilized portions of it by using cognitive radio technology. For such a system,  study the problem of joint por control and beamforming in the downlink of the cognitive radio network and formulate two iterative algorithms considering two different scenarios of spectrum sharing. In the first case, the primary network cooperates with the secondary network to jointly optimize the transmit beamforming ights and total transmitted por by both networks subject to signal to interference plus noise ratio (SINR) constraints of both primary and secondary users. In the second case, the secondary network jointly optimizes the transmit beamforming ights and its total transmitted por satisfying the SINR constraint of the secondary users and maximum tolerable interference constraint to the primary user. Simulation results are provided to show convergence behavior of the iterative algortihms.
