COMMUNICATION DEVICE, MULTICARRIER COMMUNICATION SYSTEM, AND COMMUNICATION METHOD

摘要

An adaptive modulation and an adaptive scheduling in a communication control device are efficiently performed while suppressing total report amount of reception quality information. A communication terminal device (300) used for a multicarrier communication system in which a signal is received in a channel assigned by a communication partner among a plurality of channels, each of which is composed of at least one subcarrier, reception quality of the received signal is measured, and the reception quality information is reported to the communication partner includes a reception quality measurement unit (308) which measures the reception quality of each subcarrier and a reception quality information generation unit (309) which decides an assignment request degree of each channel to the communication partner, selects information amount for representing the reception quality information for each channel according to the assignment request degree, and generates the reception quality information represented by the selected information amount according to the measured reception quality.
