N2 - This work proposes a smart sectoring scheme for the mm Wave broadcast systems to enhance the throughput by overcoming the inefficient power consumption due to transmit-ting power to undesired user directions in traditional sectoring systems. We optimize the beam pattern of the proposed scheme so that multiple users can be simultaneously served by only one RF chain. As a result, the hardware complexity can be greatly reduced. Simulation results show that the proposed sectoring scheme significantly outperforms the traditional ones under the same numbers of RF chains and antennas. In addition, the advantage of the proposed scheme is also revealed in the complexity. That is, even with only one RF chain, the proposed system can still achieve the close performance of the traditional systems with multiple RF chains (benchmark).
