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.

Description

technical field [0001] The present invention relates to a transmitting device for transmitting data to at least one of a plurality of receiving devices through a channel shared by a plurality of receiving devices using a wireless signal, and more particularly relates to a transmitting device which A receiving device is selected, transmission data to be transmitted to the selected receiving device is assigned to a channel, and the data is transmitted to the selected receiving device to improve throughput. Furthermore, the present invention also relates to a base station apparatus using this technique. Furthermore, the present invention also relates to an allocation method for allocating transmission data to be transmitted to a receiving device selected from a plurality of receiving devices to a wireless signal channel shared by the plurality of receiving devices, and more specifically, to An allocation method that improves throughput. Background technique [0002] As a tran...
