Abstract：In order to achieve efficient coordination multiple point downlink transmission, a single iteration of distributed collaborative beamforming algorithm is proposed based on the merit of maximizing the minimum SINR, and the global convergence of the proposed algorithm is proven. Furthermore, a distributed coordinated user scheduling algorithm is developed by using characteristics of optimum beam in the proposed algorithm. Simulation results show that the proposed distributed coordinated beamforming and user scheduling algorithm is superior to existing algorithms in term of the minimum user SINR performance, and only a small amount of information exchange between base stations.
