1. A pre-processing method for cooperative communication, comprising:
obtaining Multiple-Input Multiple-Output (MIMO) Cooperation Area (CA) information, wherein the MIMO CA information comprises a corresponding relation between the Base Stations (BSs) and User Equipments (UEs) served by the BSs in the MIMO CA, where the UEs include at least a first UE and a second UE; obtaining all channel matrices of the first and the second UEs, wherein each BS serving each of the first and the second UEs reports channel matrices between the UE and itself; combining the channel matrices of the first and the second UEs according to the corresponding relation between the BSs and the UE; saving the combined channel matrices of the first UE to a first computation device; saving the combined channel matrices of the second UE to a second computation device; saving the combined channel matrices of the first and the second UEs to a select computation device, wherein the select computation device is one of: the first computation device, the second computation device, or another computation device; scheduling the select computation device to perform a pre-coding computation process using the saved combined channel matrices; scheduling each of the first and the second computation devices to receive a common solution space and to perform a pre-coding computation of its corresponding UE using the common solution space; and scheduling transmission of the computation results to the serving BSs of the first and the second UEs.
