Summary:
For next generation cellular mobile communication systems, cooperative multi-point transmission technologies (CoMP), in which multiple base stations (BSs) coordinate their wireless transmission, have recently been receiving considerable attention due to their potential cell-edge throughput improvement. However, there are few studies that provide field evaluation of cooperative multi-point wireless transmission technologies in real radio-propagation environments. To field evaluate CoMP, BSs located at different sites should be synchronized to each other with high accuracy. We develop a prototype of an experimental system by using a GPS (Global Positioning System)-based inter-BS synchronous controller. We conduct field experiments on two CoMP schemes: (i) cooperative MIMO-SDM based on space division multiplexing and (ii) cooperative MIMO-SFBC based on space frequency block coding. We confirm that CoMP improves the cell-edge throughput performance in real radio-propagation environments. This paper describes the developed field experimental system and the results of the field experiments. It also shows the effectiveness of cooperative multi-point wireless transmission at the cell-edge.
