Abstract:
1. A communications system for exchange of information between a base station and a terminal by a multicarrier transmission mode using a plurality of frequency bands, the communication system comprising: a transmission data generator configured to generate frequency band set information indicating which frequency band is to be used for transmission of dedicated user data information between said base station and terminal, wherein a specific frequency band and the frequency band set including at least one frequency band without the specific frequency band are set from among a plurality of frequency bands assigned to the communications system and are made variable so that the two will not overlap; a transmitter configured to transmit the frequency band set information by using the specific frequency band to transmit dedicated user data information by using at least one frequency band and the specific frequency band at a time; and a receiver configured to receive the frequency band set information by using the specific frequency band.
