Abstract: A communication device that is used in a multi-point communication includes: a receiver, a processor and a transmitter. The receiver receives, from a target communication device included among one or more destination communication devices of the communication device, information that indicates a reception bandwidth allocated to a data transmission conducted from the communication device to the target communication device. The processor calculates a transmission bandwidth to be allocated to the data transmission conducted from the communication device to the target communication device according to information relating to the one or more destination communication devices. The transmitter transmits data to the target communication device at a rate that does not exceed an upper limit transmission rate. The upper limit transmission rate is determined according to a smaller one of values of the reception bandwidth and the transmission bandwidth.
