How to make a better use of MIMO technology to restrain and reduce the interference under the environment of multi-cell is the key. However, the problem of inter-cell interference （ICI） cannot be solved only by single base station. This paper summarizes the advances in studies of muhi-BS joint processing algorithms for inter-cell interference mitigation in MIMO cellular systems, including the summarization of the scheme for reducing the ICI in MIMO system, the muhi-BS joint processing model, the muhi-BS joint processing algorithm and its problems, the research perspective, and so on. It is of significance for the further study of multi-cell transmission technology, the practice implementation of MIMO technology, and the development of new generation mobile communications.
