Abstract:
1. A wireless communications device for wirelessly communicating with a communication partner by allocating a plurality of frequency subbands to the communication partner, the allocated frequency subbands being divided based on either a frequency domain or a frequency and a time domain, the wireless communications device comprising: a receiving unit for receiving, from the communication partner, communication quality information regarding each of one or more first frequency subbands, the one or more first frequency subbands being part of the allocated frequency subbands; an estimation unit for estimating communication quality information of a second frequency subband based on the communication quality information of each of the one or more first frequency subbands received by the receiving unit, the second frequency subband being part of the allocated frequency subbands and being different from the first frequency subbands; and a scheduling unit for allocating, to the communication partner, at least a part of the plurality of frequency subbands based on the communication quality information of each of the one or more first frequency subbands received by the receiving unit and the communication quality information of the second frequency subband estimated by the estimation unit, wherein the communication quality information of each of the one or more first frequency subbands is expressed by a value indicating communication quality, and wherein the estimation unit obtains the estimated communication quality information of the second frequency subband by subtracting an offset value from the communication quality information of one of the first frequency subbands.
