A communication apparatus and method of a mobile communication system using Orthogonal Frequency-Division Multiple Access (OFDMA). A method of transmitting an uplink acknowledge channel (ACKCH) for a downlink data channel in a mobile communication system using OFDMA includes: determining channel resources for each Control Channel Element (CCE), when a downlink control channel including at least two CCEs is received; generating uplink acknowledgement information by analyzing a received downlink data channel; assigning the at least two CCEs to at least two transmission antennas, respectively; and transmitting the uplink ACKCH including the uplink acknowledgement information through the transmission antennas.
