A User Scheduling Scheme for MU-MIMO System with Coordinated Beamforming

摘要：

In this paper, we propose a new joint user scheduling and beamforming scheme based on coordinated beamforming (CBF), as called orthogonal linear coordinated beamforming (OLCBF) for multiuser multiple-input multiple-output (MU-MIMO) systems. With the assumption that a single information stream is transmitted to each user, the base station (BS) may select a subset of users from a large number of users by utilizing the feedback of the matched channel matrix. Unlike the conventional user scheduling schemes in which transmit beamforming is merely considered, the proposed scheme optimizes transmit beamforming and receive combining jointly. Simulation results show that the proposed OLCBF scheme achieves a higher sum rate compared to the conventional orthogonal linear beamforming (OLBF) scheme with maximal ratio combining (MRC) at receivers when the number of receive antennas is more than one.
