A method for coordinated scheduling comprising: establishing, by a base station, correspondences between sub-bands and spatial information, and communicating, by the base station, the correspondences between sub-bands and spatial information with a base station of a cooperative cell ; wherein establishing, by the base station, the correspondences between sub-bands and spatial information, comprising: grouping, by the base station, user equipments in serving cell , user equipments in same group being corresponding to same spatial information, wherein spatial information is precoding matrix indicator, PMI, worst precoding matrix indicator, WPI, best precoding matrix indicator, BPI, or direction information; establishing, by the base station, the correspondences between sub-bands and groups of user equipments, thereby establishing the correspondences between sub-bands and spatial information ; obtaining, by the base station, scheduling sub-band which suffers strong interference from said cooperative cell, according to the correspondences between sub-bands and spatial information; scheduling, by the base station, the user equipments in the same group corresponding to each sub-band ; and preventing, by the base station, implementing scheduling on said scheduling sub-band which suffers strong interference from said cooperative cell, to implement that less scheduling information is transmitted via an X2 interface; wherein the user equipments in the same group have same PMI, WPI, BPI or direction information. establishing, by a base station, correspondences between sub-bands and spatial information, and communicating, by the base station, the correspondences between sub-bands and spatial information with a base station of a cooperative cell ; wherein establishing, by the base station, the correspondences between sub-bands and spatial information, comprising: grouping, by the base station, user equipments in serving cell , user equipments in same group being corresponding to same spatial information, wherein spatial information is precoding matrix indicator, PMI, worst precoding matrix indicator, WPI, best precoding matrix indicator, BPI, or direction information; establishing, by the base station, the correspondences between sub-bands and groups of user equipments, thereby establishing the correspondences between sub-bands and spatial information ; grouping, by the base station, user equipments in serving cell , user equipments in same group being corresponding to same spatial information, wherein spatial information is precoding matrix indicator, PMI, worst precoding matrix indicator, WPI, best precoding matrix indicator, BPI, or direction information; establishing, by the base station, the correspondences between sub-bands and groups of user equipments, thereby establishing the correspondences between sub-bands and spatial information ; obtaining, by the base station, scheduling sub-band which suffers strong interference from said cooperative cell, according to the correspondences between sub-bands and spatial information; scheduling, by the base station, the user equipments in the same group corresponding to each sub-band ; and preventing, by the base station, implementing scheduling on said scheduling sub-band which suffers strong interference from said cooperative cell, to implement that less scheduling information is transmitted via an X2 interface; wherein the user equipments in the same group have same PMI, WPI, BPI or direction information. <EOS>
