Abstract
A frame structure of an uplink control information transport channel in the MIMO communication system using multiple transmission antennas and multiple reception antennas, constructed such that an uplink control information transport channel for transmitting control information with respect to each of the multiple transmission antennas includes three fields: a field for acknowledgement (ACK)/negative acknowledgement (NACK) for HARQ (Hybrid Automatic Retransmission Request), a field for CQI (Channel Quality Information) and a field for weight value information with respect to each transmission antenna. Because the control information for controlling each transmission antenna is effectively transmitted, signals transmitted at each transmission antenna of the MIMO system can be controlled in real time.
