ABSTRACT:
A transmitting device for transmitting data by means of wireless signals to at least one of a plurality of receiving devices via a channel shared by the plurality of receiving devices is provided. The transmitting device receives reception quality data from each of the plurality of receiving devices; determines future predicted values relating to the reception quality of the respective receiving devices on the basis of the one or plurality of sets of past reception quality data; and selects receiving devices and assigns transmission data to be transmitted to the selected receiving devices to the channel on the basis of the future predicted values. The rate of generation of reception data errors on the side of the receiving devices and data re-transmission rate due to data errors can be reduced, and the throughput can be improved.
