영문내용 (English Abstract)	In this paper, we propose two successive multi-cell beamforming schemes for downlink multiple-input single-output (MISO) cellular networks. In the proposed multi-cell beamforming schemes, base stations (BSs) successively determine their beamforming vectors to e®ectively reduce the amount of sharing in- formation and computational complexity. Our numerical results show that the proposed schemes provide reasonable BS coordination gains while they e®ectively reduce the amount of information shared between BSs and computational complexity. It is also shown that the optimized order of successive multi-cell beamforming can notably enhance BS coordination gains.
