1. A control method of band multiplexing communications from a plurality of devices in the communication system, a rotation being established, by each device, between or among a plurality of frequency bands for transmission, the method comprising the steps of:

  • a) transmitting a symbol set from each of the plurality of devices in the communication system in each of the established transmission frequency bands;

    b) detecting, by at least one device of the plurality of devices, respective starting times of symbol sets for the other devices transmitting in the communication system for one of the plurality of frequency bands;

    c) selecting, by the at least one device, a starting time of a symbol set based on the detected starting times of symbol sets for the other devices, selected start times limiting interference between symbol sets transmitted by the at least one device and the symbol sets transmitted by the other devices to less than a threshold level; and

    d) adjusting, by the at least one device, the starting time in subsequent transmissions of respective symbols for each of the established transmission frequency bands based on the selected starting time in step (c).
