1. A method in a wireless transceiver for transmitting data to a remote node via each of two or more transmitted carrier signals, wherein a distinct outbound packet data traffic channel is mapped to each transmitted carrier signal, the method comprising:

  • forming aggregated control channel data by combining first control channel data corresponding to a first received carrier signal with second control channel data corresponding to a second received carrier signal, wherein a distinct inbound packet data traffic channel is mapped to each of the first and second received carrier signals;

    time-multiplexing the outbound packet data traffic channel for a second one of the transmitted carrier signals with third control channel data to form an outbound combined physical channel; and

    spreading the outbound combined physical channel with a spreading code to form an outbound spread spectrum signal;

    simultaneously transmitting traffic channel data to the remote node on each of the two or more outbound packet data traffic channels further comprising transmitting the outbound spread spectrum signal via the second one of the transmitted carrier signals; and

    transmitting the aggregated control channel data using one or more physical control channels mapped to a first one of the transmitted carrier signals;

    wherein the first and second control channel data comprise one or more control channel data types selected from the group consisting of;

    power control commands corresponding to each of the first and second received carrier signals;

    acknowledgement data, negative acknowledgement data, or both, corresponding to packet data received on the inbound packet data traffic channels for each of the first and second received carrier signals; and

    channel quality data corresponding to each of the first and second received carrier signals.
