Distributed Downlink Multi-Cell Processing Requiring Reduced-Rate Back-Haul Data Exchange

Different-complexity Multi-Cell Processing (MCP) schemes employing Distributed Signal-to-Interference-Leakage-plus-Noise-Ratio (SILNR) pre-coding techniques are proposed, which require reduced back-haul data exchange in comparison to the conventional-MCP structure. The authors' results demonstrate that the proposed structures are capable of increasing the achievable cell-edge throughput and offering different geographic rate profile distributions as well as meeting different delay requirements. Multiple Input Multiple Output (MIMO) system based Multi-Cell Processing (MCP), constitutes a promising enabler for improving the throughput of cell-edge Mobile Stations (MSs) by jointly pre-processing the data of all the cooperating Base Stations (BSs) involved.
