WIRELESS TRANSMISSION DEVICE, WIRELESS RECEPTION DEVICE, AND WIRELESS COMMUNICATION SYSTEM

WIPO Patent Application WO/2020/090029

A1

This wireless transmission device is provided with a transmission unit and a control unit. The transmission unit transmits a data signal by using a first wireless resource and a second wireless resource. The control unit generates a first reference signal and a second reference signal so that the second reference signal transmitted, together with the data signal, by using the second wireless resource has a prescribed shift amount with respect to a parameter associated with the first reference signal transmitted, together with the data signal, by using the first wireless resource.
