PURPOSE: A frame structure of an uplink control information transmission channel in a multi-input/output communication system is provided to control signals transmitted from each transmission antenna on a real time basis. CONSTITUTION: A frame(510) is a radio frame. The frame(510) includes three fields, that is, an ACK/NACK(512) for HARQ(Hybrid Automatic Retransmission Request), a CQI(Channel Quality Information)(514) and weight information(516) for each transmission antenna. Each field(512,514,516) has the size of 1 slot. Information allocated to the three fields(512,514,516) are control information individually applied to each transmission antenna.
