A semidefinite relaxation approach for beamforming in cooperative clustered multicell systems with novel limited feedback scheme
In this paper, we consider suboptimal cooperative downlink beamforming strategies to maximize the user sum rate in a clustered multicell system with limited feedback. We decouple the problem into multiple independent subproblems through the uplink-downlink duality theorem. Semidefinite relaxation is...
