1. A highly bandwidth-efficient communications method, comprising the steps of:

  • receiving at a base station a spread signal comprising an incoming data traffic signal spread over a plurality of discrete traffic frequencies and an incoming message segment signal spread over a plurality of link control frequencies;

    adaptively despreading the signals received at the base station by using despreading weights;

    detecting a priority interrupt flag value in said message segment signal;

    resetting a message segment buffer in said base station and storing a message segment therein, if said priority interrupt flag has a first value;

    concatenating said message segment with a previously received message segment, if said priority interrupt flag has a second value.
