      Abstract
      Gelecek nesil kablosuz iletişim sistemlerinde öngörülen veri hızlarına ulaşabilmek için bu sistemlerde frekans yeniden kullanım oranının 1 olmasına ihtiyaç¸ vardır, bu ise özellikle hücre sınırlarındaki kullanıcıların önemli ölçüde hücreler arası girişime maruz kalmalarına neden olur. Telsiz erişim terminalleri arasında işbirliği hücreler arası girişimin azaltılmasında önemli bir rol oynamaktadır. Bu bildiride çok hücreli, çok girdili çok çıktılı, dikgen frekans bölmeli çoklu erişim sistemlerinde telsiz erişim terminallerinden kullanıcılara işbirlikli veri iletimi problemini ele alıyoruz. Telsiz erişim terminallerinin aralarında kısıtlı ileti paylaşımı ile çizelgeleme ve veri iletimi yaptıkları etkin bir işbirlikli algoritma öneriyoruz.
       
      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.
