    摘要： A relay apparatus includes a first transmission/receiving means and second transmission/receiving means. The first transmission/receiving means exchanges a first relay link signal of a first frequency transmitted/received by a superordinate apparatus, with the superordinate apparatus and exchanges part of the first relay link signal as a second access link signal or a second relay link signal, at the first frequency, with a subordinate apparatus. The second transmission/receiving means exchanges the other part of the first relay link signal, which the first transmission/receiving means exchanges with the superordinate apparatus, as a third access link signal or a third relay link signal, at a second frequency that is different from the first frequency, with a subordinate apparatus.

    摘要： A radio communication system with adaptive interleaving selects between chip interleaving and bit interleaving depending upon the number of active code signals. A transmitted RF signal includes a coded information signal part and a control signal part that indicates a number of active code signals that have been combined to form the coded information signal part. The system is especially suited for MC-CDMA systems.
