Communications apparatus and communications system using multicarrier transmission mode

摘要

A communications system for exchange of information between communications apparatuses by a multicarrier transmission mode using a plurality of subcarriers, the communication system includes a transmission data generator configured to generate frequency band information indicating which frequency band is to be used for transmission of data information between said communication apparatuses and a transmitter configured to transmit the frequency band information by using a specific frequency band which is set from among a plurality of frequency band assigned to the communications system, and to transmit data information by using at least one frequency band set from among said plurality of frequency bands and a receiver configured to receive the frequency band information by using the specific frequency band, whereby one or more of said frequency band is assigned consecutive with said specific frequency band along a frequency axis.

1. A communications system for exchange of information between a base station and a terminal by a multicarrier transmission mode using a plurality of subcarriers, the communication system comprising:
the base station comprising:
a transmission data generator configured to generate dedicated frequency band information indicating which frequency band is to be used for transmission of dedicated data information between the base station and the terminal;a transmitter configured to transmit the dedicated frequency band information by using a specific frequency band which is set from among a plurality of frequency bands assigned to the communications system, and to transmit the dedicated data information by using at least one frequency band set from among said plurality of frequency bands; and the terminal comprising:
a receiver configured to receive the dedicated frequency band information by using the specific frequency band, whereinone or more of said frequency bands of the plurality of frequency bands is assigned consecutive with said specific frequency band along a frequency axis.
