Abstract

User Equipment (UE) centric coordinated beamforming (CBF) is an enabling technology in multi-cell MU-MIMO systems. It is of great importance to know the suggested cooperating set size for CBF and the corresponding performance. In this paper, a novel joint space-time-frequency proportionally fair scheduler for CBF is proposed to provide a tradeoff between the average system performance and UE fairness. The impact of the cooperating set size on system performance is predicted through the analysis of a simplified system, and then confirmed through numerical results of the whole system using the proposed scheduler.
