Transmit antenna selection scheme is developed for multiple-input multiple-output (MIMO) systems in a multicell environment. We first formulate an optimal transmit antenna selection criterion to maximize the total achievable rate. The optimal scheme, however, works in the centralized manner, requiring global channel state information and signaling overhead between cells. As a practical solution, we derive a decentralized transmit antenna selection criterion which consider not only the desired channel but also interference channel to adjacent cells. The proposed scheme works in the decentralized manner and thus eliminates the need for feedback and signaling overhead between cells. The simulation results show that the proposed scheme outperforms the conventional scheme and provides a close performance to the centralized optimal scheme in terms of the achievable rate.
