A CDMA transmission apparatus comprising: a control section that recognizes types of data included in a plurality of data items and outputs: the plurality of data items; and control information based on the recognized type of data included in the plurality of data items; an apportion section that apportions the plurality of data items to a plurality of groups; a multiplexing section that code division multiplexes the apportioned data items for each said group; and a transmission section that transmits the code division multiplexed data items for each said group at the same transmission timing_using a transmission antenna corresponding to each said group, wherein said apportion section generates a replica of specific data item among the plurality of data items and apportions said specific data item and the replica of said specific data item to at least two groups among said plurality of groups, and said apportion section apportions other data items than said specific data item among the plurality of data items substantially equally among said plurality of groups without generating a replica of said other data items, and wherein said apportion section apportions the specific data item based on the control information from the control section, said multiplexing section code division multiplexes said apportioned specific data item and replica of said specific data item using spreading codes which differ from one apportioned group to another; and said transmission section is configured to transmit the code division multiplexed data items of said at least two groups using at least two transmission antennas. a control section that recognizes types of data included in a plurality of data items and outputs: the plurality of data items; and control information based on the recognized type of data included in the plurality of data items; an apportion section that apportions the plurality of data items to a plurality of groups; a multiplexing section that code division multiplexes the apportioned data items for each said group; and a transmission section that transmits the code division multiplexed data items for each said group at the same transmission timing_using a transmission antenna corresponding to each said group, wherein said apportion section generates a replica of specific data item among the plurality of data items and apportions said specific data item and the replica of said specific data item to at least two groups among said plurality of groups, and said apportion section apportions other data items than said specific data item among the plurality of data items substantially equally among said plurality of groups without generating a replica of said other data items, and wherein said apportion section apportions the specific data item based on the control information from the control section, said multiplexing section code division multiplexes said apportioned specific data item and replica of said specific data item using spreading codes which differ from one apportioned group to another; and said transmission section is configured to transmit the code division multiplexed data items of said at least two groups using at least two transmission antennas.
