Patent ID: 7551589

Claim:
A frame of an uplink control information transport channel in a multi-input/multi-output (MIMO) communication system using multiple transmission antennas and multiple reception antennas, constructed such that the uplink control information transport channel for transmitting control information with respect to each of the multiple transmission antennas includes the frame, the frame comprising: 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 of the multiple transmission antennas, wherein the uplink control information transport channel is divided into as many sections as number of the multiple transmission antennas, and each section comprises three fields allocated to each of the multiple transmission antennas, wherein the CQI includes at least one of a transmission block size, information on a modulation method, information on the number of a High Speed Downlink Shared Channel (HS-DSCH) and power offset information with respect to a Dedicated Physical Data Channel (DPDCH) for transmitting the HS-DSCH.
