摘要： In a multiuser Multiple Input Multiple Output (MIMO) radio communication system, a transmitter receives channel quality information transmitted from receivers, schedules resource for the receivers within a corresponding scheduling epoch based on the received channel quality information. Thereafter, the transmitter pre-codes signals to be transmitted to the resource-scheduled receivers in a predetermined coding method before transmission, thereby maximizing system transmission efficiency.
