Abstract

Recently, vertical sectorization (VS) has been proposed for multiple-input multiple-output (MIMO) transmission in long term evolution advanced (LTE-A) downlink systems. In this paper, we will investigate MIMO transmission with VS for LTE-A systems. We first divide each cell into two sectors in vertical direction so that more users can be co-scheduled and more refined beams can be formed in each sector. We then address how to jointly optimize two tilt angles, user scheduling, and resource block allocation for a practical LTE-A system, and provide an efficient VS-based MIMO scheduling algorithm with low-complexity. The performance improvement of the proposed algorithm is demonstrated by system level simulation.
