Abstract
A pre-processing method and system for cooperative communication are provided. The method includes: after obtaining channel matrices collected by a Base Station (BS), obtaining Multiple-Input Multiple-Output (MIMO) Cooperation Area (CA) information, in which the MIMO CA information includes cooperation information between BSs, and the cooperation information between the BSs is used to determine an interference relation between MIMO CAs; combining the channel matrices of a User Equipment (UE) according to the interference relation between the MIMO CAs; and performing pre-coding computation of the UE by using the combined channel matrices.
