1. A method for efficient utilization of radio channel resources in a communication system, wherein a sequence of time slots is provided on each of the radio channel resources for packetized communications, the method comprising the steps of:

  • a) preempting, on at least one of the radio channel resources, packetized information contained within at least one time slot of said sequence of time slots every N time slots to produce at least one preempted time slot;

    b) utilizing the at least one preempted time slot for transmitting or receiving signaling information, the signaling information being superimposed on the at least one preempted time slot; and

    c) indicating a location of the preempted time slot using an independent broadcast channel, the independent broadcast channel allowing the communication system to distinguish the signaling information from the packetized information.
