Title:
BASE-STATION DEVICE, WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION DEVICE, METHOD FOR ALLOCATING FREQUENCY BAND, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2013/084908
Kind Code:
A1
Abstract:
The present invention enables suppression of the decline in use efficiency of frequency bands, even if the number of points when performing an orthogonal transform is constrained. The invention is a base-station device characterized in being provided with: an allocation determination unit for allocating a subcarrier-frequency band to each of a plurality of communication devices for orthogonally transforming a transmission signal and transmitting the signal by placing the signal on a subcarrier; a communication-device selection unit for selecting, from the plurality of communication devices, a communication device for which the number of subcarriers included in the frequency band allocated by the allocation determination unit is not a predetermined number; and a frequency-band adjustment unit for changing, from the frequency band allocated by the allocation determination unit, the frequency band allocated to each of the selected communication devices; the frequency-band adjustment unit performing the change so that the number of subcarriers included in each of the frequency bands resulting from the change matches the predetermined number.
