This　paper　addresses　the　problem　cooperative　downlink　transmission　in　multicell　multiantenna　cellular　networks.　We　have　presented　scheme　for　base　station　coordination　and　cooperation　in　MIMO　with　zero　forcing　beamformig　system.　Firstly,　a　projected　channel　matrices　is　given　and　it　make　the　beams　steer　into　the　preferred　user　direction.　Secondly,　partial　collaboration　transmission　and　distributed　scheduling　method　have　been　proposed.　These　approaches　can　reduce　the　complexity　of　user　selection　and　achieve　reasonable　performance.
