This paper considers designing hybrid beamformer (HBF) to enhance communication performance and reduce inter-cell interference for massive MIMO system. The goal is minimizing the transmission power under individual signal-to-interference-plus-noise ratio (SINR) and sidelobe level (SLL) constraints, which is a non-convex optimization problem. To tackle the SLL over continuous intervals, we convert it into a finite number of constraints. Then we give the optimal solution of the problem for different RF chain to user number ratio. Simulation results show proposed algorithm not only effectively reduce inter-cell interference but also exhibits high numerical stability in multiuser massive MIMO system.
