More Information
Summary:A data transceiving device in a communication system and a method thereof are provided to prevent performance from being deteriorated even though the number of precoding matrices is increased, and to reduce feedback quantities of channel quality information. A base station checks whether transmission data to be transmitted to each terminal exists(711). If so, the base station carries out a precoding process for the transmission data by using precoding matrices in predetermined order(713). The base station transmits the precoded data to each terminal(715).
