Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: With very high carrier frequencies (such as millimeter-wave (mmW) bands), a very large number of antennas can be packed at the base station (BS). For this kind of high dimensional channel, it is desirable to exploit signal directions to estimate the channel directions. ,  analyze the performance of the direction of arrival (DoA) estimation based on unitary ESPRIT algorithm assuming time division duplex (TDD) wideband system. The mean-squared error (MSE) of the 2D DoA estimation of a multipath signal impinging on a planar antenna array is derived. Accordingly,  propose a por allocation strategy that counts for the DoA estimation error. The achievable rate characterization suggests that our por allocation strategy outperforms the traditional water-filling solution.
