METHOD FOR TRANSMITTING AND RECEIVING SIGNALS USING COLLABORATIVE MIMO SCHEME

摘要

A method for transceiving a signal in a cooperative MIMO(Multi-Input Multi-Output) mode is provided to perform precoding by sharing precoding matrix information received from a terminal in a closed-loop mode when a data signal for one terminal is transmitted in a plurality of base stations in the multi-cell environment. A channel signal, which is received from cooperative base stations including a serving base station and more than one neighboring base station, which performs a cooperative MIMO mode with the serving base station, is measured. A precoding matrix index for each cooperative base station is determined and reported to the serving base station. The same or independent signal is received from the cooperative base stations.
