A method and device for multiple-cell collaborative communication in a multiple input multiple output (MIMO) system are disclosed by the present invention. In said method, base stations participating in multiple-cell collaborative MIMO communication perform precoding and scheduling one by one. At first, a first base station selects the mobile terminals participating in the collaborative communication and performs transmission setting, including pre-coding setting; then the scheduling and setting results of the first base station are kept invariant, so that a second base station selects the mobile terminals participating in the collaborative communication and performs transmission setting, including pre-coding setting, according to the scheduling and setting results of the first base station. If a third base station participates in the multiple-cell collaborative MIMO communication, the scheduling and setting results of the first and second base stations are kept invariant, so that the third base station selects the mobile terminals participating in the collaborative communication and performs transmission setting, including pre-coding setting, according to the scheduling and setting results of the first and second base stations. Based on the gradual collaborative communication method, fully distributed multiple-cell collaborative MIMO communication can be achieved.
