Abstract  Abstract

The invention claims a communication device and communication system based on multi-carrier transmission mode wherein the communication system uses multi-carrier transmission mode for communication between a plurality of communication devices (10 20) in the communication system the distribution is divided into a plurality of frequency band having a constant bandwidth (e.g. frequency band 1 to the whole frequency band of the communication system 4) a division of the frequency band of the specific frequency band (such as 1) to the transmission frequency band information should be used so as to determine the time when the communication device of the rest frequency bands (frequency band 2 to frequency band 4). Here the specific frequency band as comprising control channel information of said using frequency band information and the data channel information to be transmitted to the main frequency band of the main band add further data channel information of the expanding frequency band. And the main frequency band and expanding frequency band can be changed along with the time corresponding to the use of the frequency band or increasing the number of the frequency band. Optimizing each of the main frequency band and each said expanding frequency band are carried out multiplexing via several of said communication device.

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.
