An efficient shared relay beamforming scheme for multi-cell multi-user LTE-A cooperative networks

The recent resurgence in interest in the small cells is being driven primarily by market demand for higher network capacity to host existing and new data services. Cell coverage continues to be an issue due to limited indoor penetration at higher transmission frequencies. For such cases, small cells are likely to play a vital role in providing indoor coverage and capacity. In this paper, we proposed a shared relay beamforming scheme for multi-user multi-cell (MCMU) cooperative networks. Here, the multi-cell shared a relay cell for cooperation. By doing so, the average throughput is increased. The simulation result shows the effectiveness of the proposed scheme.
