Document Type and Number:
WIPO Patent Application WO/2018/123058
Kind Code:
A1
Abstract:
Provided is a wireless communication device that includes a reception unit, a selection unit, a modulation unit, and a transmission unit. The selection unit selects an ACK as a response signal when it is determined that demodulation of reception data has succeeded, and selects any one of a plurality of NACKs as a response signal when it is determined that the demodulation of the reception data has failed. When an ACK is selected by the selection unit, the modulation unit modulates the response signal so that the symbol of the ACK is arranged in one region across one of I axis and Q axis on an IQ plane. When any one of the plurality of NACKs is selected by the selection unit, the modulation unit modulates the response signal so that the symbol of the NACK selected by the selection unit is arranged along a straight line (40) parallel to the one axis in the other region across the one axis on the IQ plane. The transmission unit transmits the response signal modulated by the modulation unit to another device.
