Efficient Shared Relay Beamforming Method for Multi-Cell Multi-User LTE-A Cooperative Networks and Communication System using the same

摘要

The recent increase of interest in a small cell is led by a market demand on a high network capacity. A cell coverage makes a problem due to a limited indoor propagation in a high transmission frequency. In this case, the small cell plays an important role for providing the capacity and an indoor coverage. According to the embodiment of the present invention, suggested is a shared relay beamforming method for a multi-user multi-cell (MCMU) cooperative network. Wherein, a multi-cell shares a relay cell for cooperation. Thereby, an average processing quantity is increased.
