Title:

TRANSMISSION DEVICE, RECEIVING DEVICE, AND RADIO COMMUNICATION METHOD

Document Type and Number:

WIPO Patent Application WO/2019/012669

Kind Code:

A1

Abstract:

In order to achieve a DMRS arrangement pattern suitable to future radio communication systems, this transmission device is provided with a transmission unit which transmits a data channel, and a control unit which controls arrangement of a reference signal used in demodulation of the data channel. The control unit determines an arrangement pattern of the reference signal in the frequency direction and/or the time direction on the basis of the number of symbols transmitted on the data channel.
