Robust Multicell Cooperation in MIMO-OFDMA Networks

In future communication systems, the constraint of resource allocation is a challenging topic. The cell edge users in wireless systems experience low Signal to Interference and Noise Ratio (SINR) due to the high Inter-Cell Interference (ICI) and cannot fully benefit from Multiple-Input Multiple-Output (MIMO) multi-stream transmission capability. In this paper, a practical approach to the multi-cell co-operation using joint user scheduling and rank coordination is proposed. In this, the cells coordinate among themselves using the transmission ranks (the number of transmitted streams) to maximize a network utility function, i.e., the throughput.
