Novel Approach for Multicell Mimo-ofdma Network Based on Rank Coordination

A common approach for multicell MIMO-OFDMA network based on rank coordination is to impose sparsity constraints on the cell structure. Such constraints, however may greatly complicate the control design procedure. This paper puts forward an alternative structure, which is well suited for control purposes. The structure appears as the optimal solution to the class of coordination problems arising in multi-agent applications. The proposed method comprises a decentralized parts, complemented by a rank coordination term. The performance is measured in terms of the average cell spectral efficiency and the 5% of cell edge spectral efficiency.
