Abstract  Abstract

A communication system in which communication devices (10 20) communicate with each other by multicarrier transmission method. The whole frequency band assigned to the communication system is divided into frequency bands (for example band 1 to band 4) with a constant band width. Using a specific band (for example band 1) of the divided bands use frequency band information is transmitted and thereby assignment of the other bands (band 2 to band 4) to be used by the communication devices is determined. The specific band is used as the main band for transmitting not only control channel information including the use frequency band information but also data channel information. To the main band an expansion band for transmitting additional data channel information can be added. For the main and expansion bands the above frequency bands to be used can be varied with time and the number of frequency bands can be changed. Both the main band expansion bands are preferably multiplexedly used by some communication devices.
