COMMUNICATION CONTROL DEVICE, COMMUNICATION TERMINAL DEVICE, RADIO COMMUNICATION SYSTEM, AND COMMUNICATION METHOD

摘要

The amount of information reported by a communication terminal apparatus to a communication control apparatus is reduced based on the congestion status of communication. Communication control 100 apparatus communicates with a communication terminal apparatus using frequency channels composed of two or more sub-channels defined by a predetermined frequency band includes: receiver 113 for receiving information data destined to the terminal apparatus; scheduler 113 for generating assignment information indicating the status of assignment of the received information data to each sub-channel; congestion information generator 103 for generating congestion information indicating the congestion degree of each sub-channel based on the generated assignment information; control information generator 104 for generating control information including the generated congestion information; and transmitter 111 for transmitting the generated control information to the terminal apparatus.
