摘要
A method and an apparatus for use in a multiuser radio communication system for transmitting and receiving a signal in a Multiple Input and Multiple Output (MIMO) broadcast channel with an imperfect Channel State Information at the Transmitter (CSIT) are provided. The signal transmission/reception method includes receiving CSI from each of a plurality of receivers, determining a transmit power and a transmission rate based on the CSI qualities of the plurality of receivers calculated from the CSI from each of the plurality of receivers, and transmitting the signal using the transmit power and the transmission rate. The present disclosure is capable of maximizing system throughput in wireless communication system.
