Title:
TRANSMISSION DEVICE, RECEPTION DEVICE, AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/021474
Kind Code:
A1
Abstract:
In order to implement transmission and/or reception using a demodulation reference signal suitable for a future wireless communication system, one aspect of a transmission device according to the present invention comprises: a transmission unit that transmits a data channel to which a first time unit and/or a second time unit shorter than the first time unit is applied, and transmits reference signals for use in demodulation of the data channel; and a control unit that controls allocation of a first reference signal for use in demodulation of a data channel to which the first time unit is applied and controls allocation of a second reference signal for use in demodulation of a data channel to which the second time unit is applied. The control unit applies the same configuration to the first reference signal and the second reference signal.
