Low-Complexity User Scheduling with Switched Tilting for 3D Cellular Systems
We propose a low-complexity user scheduling scheme to enhance the sum rate performance for a multicell downlink system, in which the base station (BS) is equipped with a large-scale active antenna array. First, we divide each cell into N regions according to the vertical beamwidth of the BS antennas...
