    摘要： Disclosed in the present invention is a coordinated scheduling method which includes that: a base station establishes the correspondences between sub-bands and spatial information, and communicates the correspondences between sub-bands and spatial information with the base station of a cooperative cell (301); said base station implements coordinated scheduling with the base station of said cooperative cell according to the correspondences between sub-bands and spatial information (302). The present invention implements that less scheduling information is transmitted via an X2 interface, and thus promotes the application of the CBF solution in an actual system.

    摘要： Embodiments of the present invention disclose an information transmission method and equipment based on CoMP transmission. In the method, a user equipment determines a main transmission point. The user equipment determines RANK information of the main transmission point as well as channel state information corresponding to the RANK information. The user equipment sends the RANK information of the main transmission point and the channel state information to a network side equipment. In the embodiments of the present invention, the UE reports channel state information of limited RANK of every transmission point, channel state information of unlimited RANK of the main transmission point, and relative phase information between the transmission points, etc., to the network side equipment, thereby helping the network side to better implement flexible selection and dynamic switchover of transmission schemes. Moreover, it does not notably increase feedback expenses for the UE.
