Achieving the targeted data rates for next generation wireless communication systems requires using frequency reuse ratio 1 in these systems, but this in turn results in significant intercell interference observed especially by the users near cell edges. Cooperation between the base stations plays an important role in reducing the intercell interference. In this paper, we consider the problem of cooperative data transmission from the base stations to the users in multicellular multiple input multiple output (MIMO) orthogonal frequency division multiple access (OFDMA) systems. We propose an efficient cooperative scheduling and data transmission scheme, requiring limited information exchange between the base stations. ©2009 IEEE.
