Abstract
This paper considers a joint beamforming design problem in the multicell multicast system with multiple groups that provide different multicast services. Inspired by previous works in the literature, we apply semidefinite relaxation (SDR) to perform joint beamforming design among the cooperating base stations. Per-cell power constraints are considered which make solving the problem challenging. We propose two algorithms to accommodate the per-cell power constraints while performing joint beamforming. Simulation results show that the proposed algorithms provide better performance compared to the existing multicast methods in the multicell environment.
