1. A method of wideband communication between a base station and a plurality of remote terminals within each cell of a multi-cell network, comprising:

  • 1) at each base station, processing a base input data signal for broadcast to remote terminals in the same cell by;

    demultiplexing the base input data signal into a plurality of base channels;

    modulating a portion of the base input data signal in each base channel;

    time division multiplexing each modulated base channel within one or more data time periods to form a base output data signal;

    spreading the base output data signal with a pseudo-random noise signal to form a broadcast signal;

    broadcasting the broadcast signal to be received by the plurality of remote terminals within the same cell; and

    , 2) at each remote terminal, processing a terminal data signal for transmission to the base station in the same cell by;

    demultiplexing the terminal data signal into one or more terminal channels;

    modulating a portion of the terminal input data signal in each terminal channel;

    spreading each modulated terminal channel with an orthogonal code to form an orthogonal signal;

    summing a predetermined number of the orthogonal signals to form a terminal signal; and

    scheduling the terminal signal for transmission by the remote terminal to be received by the base station in the same cell synchronously with terminal signals from other remote terminals in the same cell.
