Example implementations described herein are directed to forming additional sectors in the vertical domain (called vertical sectorization) for a base station (BS). Example implementations may involve various methods of forming and operating vertical sectors. Example implementations may involve a BS configured with a two dimensional active antenna grid such as in a Full Dimensional Multiple Input Multiple Output (FD-MIMO) system. Example implementations may allow a network operator to create vertical sectors, perform initial configuration and optimize the subsequent data rate performance.
