This is the first technical contribution in the IEEE 802.16m WiMAX standard group to investigate how many base stations (BS) should be coordinated for multi-BS joint MIMO processing. It provides convincing quantitative numerical results to demonstrate that the proposed 3-cell collaborative MIMO processing is feasible and easy to implement. The IEEE 802.16m WiMAX group has adopted the key concept of this contribution and specified in the standard.
